What is Microprocessor? Give the power supply & clock frequency of 8085<br />A microprocessor is a multipurpose, programmable logic device that reads<br />binary instructions from a storage device called memory accepts binary data as<br />input and processes data according to those instructions and provides result as<br />output. The power supply of 8085 is +5V and clock frequency in 3MHz.<br />2. List few applications of microprocessor-based system.<br />It is used:<br />i. For measurements, display and control of current, voltage,<br />temperature, pressure, etc.<br />ii. For traffic control and industrial tool control.<br />iii. For speed control of machines.<br />3. What are the functions of an accumulator?<br />The accumulator is the register associated with the ALU operations and<br />sometimes I/O operations. It is an integral part of ALU. It holds one of data to be<br />processed by ALU. It also temporarily stores the result of the operation performed<br />by the ALU.<br />4. List the 16 – bit registers of 8085 microprocessor.<br />Stack pointer (SP) and Program counter (PC).<br />5. List the allowed register pairs of 8085.<br />• B-C register pair<br />• D-E register pair<br />• H-L register pair<br />6. Mention the purpose of SID and SOD lines<br />SID (Serial input data line):<br />It is an input line through which the microprocessor accepts serial<br />data.<br />SOD (Serial output data line):<br />It is an output line through which the microprocessor sends output<br />serial data.<br />7. What is an Opcode?<br />The part of the instruction that specifies the operation to be performed is<br />called the operation code or opcode.<br />8. What is the function of IO/M signal in the 8085?<br />It is a status signal. It is used to differentiate between memory locations<br />and I/O operations. When this signal is low (IO/M = 0) it denotes the<br />memory related operations. When this signal is high (IO/M = 1) it denotes<br />an I/O operation.<br />9. What is an Operand?<br />The data on which the operation is to be performed is called as an<br />Operand.<br />10. How many operations are there in the instruction set of 8085<br />microprocessor?<br />There are 74 operations in the 8085 microprocessor.<br />11. List out the five categories of the 8085 instructions. Give examples of the<br />instructions for each group.<br />• Data transfer group – MOV, MVI, LXI.<br />• Arithmetic group – ADD, SUB, INR.<br />• Logical group –ANA, XRA, CMP.<br />• Branch group – JMP, JNZ, CALL.<br />• Stack I/O and Machine control group – PUSH, POP, IN, HLT.<br />12. Explain the difference between a JMP instruction and CALL instruction.<br />A JMP instruction permanently changes the program counter. A CALL<br />instruction leaves information on the stack so that the original program execution<br />sequence can be resumed.<br />13. Explain the purpose of the I/O instructions IN and OUT.<br />The IN instruction is used to move data from an I/O port into the<br />accumulator.<br />The OUT instruction is used to move data from the accumulator to an I/O<br />port.<br />The IN & OUT instructions are used only on microprocessor, which use a<br />separate address space for interfacing.<br />14. What is the difference between the shift and rotate instructions?<br />A rotate instruction is a closed loop instruction. That is, the data moved<br />out at one end is put back in at the other end. The shift instruction loses the data<br />that is moved out of the last bit locations.<br />15. How many address lines in a 4096 x 8 EPROM CHIP?<br />12 address lines.<br />16. Control signals used for DMA operation are ____________<br />HOLD & HLDA.<br />17. What is meant by Wait State?<br />This state is used by slow peripheral devices. The peripheral devices can<br />transfer the data to or from the microprocessor by using READY input line. The<br />microprocessor remains in wait state as long as READY line is low. During the<br />wait state, the contents of the address, address/data and control buses are held<br />constant.<br />18. List the four instructions which control the interrupt structure of the 8085<br />microprocessor.<br />• DI ( Disable Interrupts )<br />• EI ( Enable Interrupts )<br />• RIM ( Read Interrupt Masks )<br />• SIM ( Set Interrupt Masks )<br />19. What is meant by polling?<br />Polling or device polling is a process which identifies the device that has<br />interrupted the microprocessor.<br />20. What is meant by interrupt?<br />Interrupt is an external signal that causes a microprocessor to jump to a<br />specific subroutine.<br />21. Explain priority interrupts of 8085.<br />The 8085 microprocessor has five interrupt inputs. They are TRAP, RST<br />7.5, RST 6.5, RST 5.5, and INTR. These interrupts have a fixed priority of<br />interrupt service.<br />If two or more interrupts go high at the same time, the 8085 will service<br />them on priority basis. The TRAP has the highest priority followed bye RST 7.5,<br />RST 6.5, RST 5.5. The priority of interrupts in 8085 is shown in the table.<br />Interrupts Priority<br />TRAP<br />RST 7.5<br />RST 6.5<br />RST 5.5<br />INTR<br />1<br />2<br />3<br />4<br />5<br />22. What is a microcomputer?<br />A computer that is designed using a microprocessor as its CPU is called<br />microcomputer.<br />23. What is the signal classification of 8085<br />All the signals of 8085 can be classified into 6 groups<br />• Address bus<br />• Data bus<br />• Control and status signals<br />• Power supply and frequency signals<br />• Externally initiated signals<br />• Serial I/O ports<br />24. What are operations performed on data in 8085<br />The various operations performed are<br />• Store 8-bit data<br />• Perform arithmetic and logical operations<br />• Test for conditions<br />• Sequence the execution of instructions<br />• Store data temporarily during execution in the defined R/W<br />memory locations called the stack<br />25. Steps involved to fetch a byte in 8085<br />i. The PC places the 16-bit memory address on the address bus<br />ii. The control unit sends the control signal RD to enable the memory<br />chip<br />iii. The byte from the memory location is placed on the data bus<br />iv. The byte is placed in the instruction decoder of the microprocessor and<br />the task is carried out according to the instruction<br />26. How many interrupts does 8085 have, mention them<br />The 8085 has 5 interrupt signals; they are INTR, RST7.5, RST6.5, RST5.5<br />and TRAP<br />27. Basic concepts in memory interfacing<br />The primary function of memory interfacing is that the microprocessor<br />should be able to read from and write into a given register of a memory chip. To<br />perform these operations the microprocessor should<br />• Be able to select the chip<br />• Identify the register<br />• Enable the appropriate buffer<br />28. Define instruction cycle, machine cycle and T-state<br />Instruction cycle is defined, as the time required completing the execution<br />of an instruction. Machine cycle is defined as the time required completing one<br />operation of accessing memory, I/O or acknowledging an external request. Tcycle<br />is defined as one subdivision of the operation performed in one clock period<br />29. What is an instruction?<br />An instruction is a binary pattern entered through an input device to<br />command the microprocessor to perform that specific function<br />30. What is the use of ALE<br />The ALE is used to latch the lower order address so that it can be available<br />in T2 and T3 and used for identifying the memory address. During T1 the ALE<br />goes high, the latch is transparent ie, the output changes according to the input<br />data, so the output of the latch is the lower order address. When ALE goes low the<br />lower order address is latched until the next ALE.<br />31. How many machine cycles does 8085 have, mention them<br />The 8085 have seven machine cycles. They are<br />• Opcode fetch<br />• Memory read<br />• Memory write<br />• I/O read<br />• I/O write<br />• Interrupt acknowledge<br />• Bus idle<br />32. Explain the signals HOLD, READY and SID<br />HOLD indicates that a peripheral such as DMA controller is requesting<br />the use of address bus, data bus and control bus. READY is used to delay the<br />microprocessor read or write cycles until a slow responding peripheral is ready to<br />send or accept data. SID is used to accept serial data bit by bit<br />33. Mention the categories of instruction and give two examples for each<br />category<br />The instructions of 8085 can be categorized into the following five<br />• Data transfer MOV Rd,Rs STA 16-bit<br />• Arithmetic ADD R DCR M<br />• Logical XRI 8-bit RAR<br />• Branching JNZ CALL 16-bit<br />• Machine control HLT NOP<br />34. Explain LDA, STA and DAA instructions<br />LDA copies the data byte into accumulator from the memory location<br />specified by the 16-bit address. STA copies the data byte from the accumulator in<br />the memory location specified by 16-bit address. DAA changes the contents of<br />the accumulator from binary to 4-bit BCD digits.<br />35. Explain the different instruction formats with examples<br />The instruction set is grouped into the following formats<br />• One byte instruction MOV C,A<br />• Two byte instruction MVI A,39H<br />• Three byte instruction JMP 2345H<br />36. What is the use of addressing modes, mention the different types<br />The various formats of specifying the operands are called addressing modes, it is used to<br />access the operands or data. The different types are as follows<br />• Immediate addressing<br />• Register addressing<br />• Direct addressing<br />• Indirect addressing<br />• Implicit addressing<br />37. What is the use of bi-directional buffers?<br />It is used to increase the driving capacity of the data bus. The data bus of a<br />microcomputer system is bi-directional, so it requires a buffer that allows the data<br />to flow in both directions.<br />38. Give the register organization of 8085<br />39. Define stack and explain stack related instructions<br />The stack is a group of memory locations in the R/W memory that is used<br />for the temporary storage of binary information during the execution of the<br />program. The stack related instructions are PUSH & POP<br />40. Why do we use XRA A instruction<br />The XRA A instruction is used to clear the contents of the Accumulator<br />and store the value 00H.<br />41. Compare CALL and PUSH instructions<br />CALL PUSH<br />When CALL is executed the<br />microprocessor automatically stores the<br />16-bit address of the instruction next to<br />CALL on the stack<br />The programmer uses the instruction<br />PUSH to save the contents of the register<br />pair on the stack<br />When CALL is executed the stack pointer<br />is decremented by two<br />When PUSH is executed the stack<br />pointer register is decremented by two<br />W(8)<br />Temp. Reg<br />Z(8)<br />Temp. Reg<br />B(8)<br />Register<br />C(8)<br />Register<br />D(8)<br />Register<br />E(8)<br />Register<br />H(8)<br />Register<br />L(8)<br />Register<br />Stack Pointer(16)<br />Program Counter(16)<br />42. What is Microcontroller and Microcomputer<br />Microcontroller is a device that includes microprocessor; memory and I/O<br />signal lines on a single chip, fabricated using VLSI technology. Microcomputer is<br />a computer that is designed using microprocessor as its CPU. It includes<br />microprocessor, memory and I/O.<br />43. Define Flags<br />The flags are used to reflect the data conditions in the accumulator. The 8085<br />flags are S-Sign flag, Z-Zero flag, AC-Auxiliary carry flag, P-Parity flag, CYCarry<br />flag<br />D7 D6 D5 D4 D3 D2 D1 D0<br />S Z AC P CY<br />44. How does the microprocessor differentiate between data and instruction<br />When the first m/c code of an instruction is fetched and decoded in the<br />instruction register, the microprocessor recognizes the number of bytes required<br />to fetch the entire instruction. For example MVI A, Data, the second byte is<br />always considered as data. If the data byte is omitted by mistake whatever is in<br />that memory location will be considered as data & the byte after the “data” will be<br />treated as the next instruction.<br />45. Compare RET and POP<br />RET POP<br />RET transfers the contents of the top two<br />locations of the stack to the PC<br />POP transfers the contents of the top two<br />locations of the stack to the specified register<br />pair<br />When RET is executed the SP is incremented<br />by two<br />When POP is executed the SP is incremented<br />by two<br />Has 8 conditional RETURN instructions No conditional POP instructions<br />46. What is assembler<br />The assembler translates the assembly language program text which is given as input<br />to the assembler to their binary equivalents known as object code. The time required to<br />translate the assembly code to object code is called access time. The assembler checks for<br />syntax errors & displays them before giving the object code.<br />47. What is loader<br />The loader copies the program into the computer’s main memory at<br />load time and begins the program execution at execution time.<br />48. What is linker<br />A linker is a program used to join together several object files into one large object<br />file. For large programs it is more efficient to divide the large program modules into<br />smaller modules. Each module is individually written, tested & debugged. When all the<br />modules work they are linked together to form a large functioning program.<br />49. Explain ALIGN & ASSUME<br />The ALIGN directive forces the assembler to align the next segment at an address<br />divisible by specified divisor. The format is ALIGN number where number can be 2, 4, 8<br />or 16. Example ALIGN 8.<br />The ASSUME directive assigns a logical segment to a physical segment at any given<br />time. It tells the assembler what address will be in the segment registers at execution<br />time. Example ASSUME CS: code, DS: data, SS: stack<br />50. Explain PTR & GROUP<br />A program may contain several segments of the same type. The GROUP directive<br />collects them under a single name so they can reside in a single segment, usually a data<br />segment. The format is Name GROUP Seg-name,…..Seg-name<br />PTR is used to assign a specific type to a variable or a label. It is also used to<br />override the declared type of a variable.<br />51. Explain about MODEL<br />This directive provides short cuts in defining segments. It initializes memory model<br />before defining any segment. The memory model can be SMALL, MEDIUM,<br />COMPACT or LARGE.<br />Model Code segments Data segments<br />Small One One<br />Medium Multiple One<br />Compact One Multiple<br />Large Multiple Multiple<br />52. Explain PROC & ENDP<br />PROC directive defines the procedures in the program. The procedure name must be<br />unique. After PROC the term NEAR or FAR are used to specify the type of procedure.<br />Example FACT PROC FAR. ENDP is used along with PROC and defines the end of the<br />procedure.<br />53. Explain SEGMENT & ENDS<br />An assembly program in .EXE format consists of one or more segments. The starts of<br />these segments are defined by SEGMENT and the end of the segment is indicated by<br />ENDS directive. Format Name SEGMENT<br />Name ENDS<br />54. Explain TITLE & TYPE<br />The TITLE directive helps to control the format of a listing of an assembled program.<br />It causes a title for the program to print on line 2 of each page of the program listing.<br />Maximum 60 characters are allowed. Format TITLE text.<br />TYPE operator tells the assembler to determine the type of specified variable in<br />bytes. For bytes the assembler gives a value 1, for word 2 & double word 4.<br />55. Define SOP<br />The segment override prefix allows the programmer to deviate from the default<br />segment<br />Eg : MOV CS : [BX] , AL<br />56. Define variable<br />A variable is an identifier that is associated with the first byte of data item. In<br />assembly language statement: COUNT DB 20H, COUNT is the variable.<br />57. What are procedures<br />Procedures are a group of instructions stored as a separate program in memory and it<br />is called from the main program whenever required. The type of procedure depends on<br />where the procedures are stored in memory. If it is in the same code segment as that of<br />the main program then it is a near procedure otherwise it is a far procedure.<br />58. Explain the linking process<br />A linker is a program used to join together several object files into one large object<br />file. The linker produces a link file which contains the binary codes for all the combined<br />modules. It also produces a link map which contains the address information about the<br />link files. The linker does not assign absolute addresses but only relative address starting<br />from zero, so the programs are relocatable & can be put anywhere in memory to be run.<br />59. Explain about passing parameters using registers with example<br />Procedures process some data or address variable from the main program, for<br />processing it is necessary to pass the address variables or data. This is called passing<br />parameters to procedures. In passing parameters using registers the data to be passed is<br />stored in registers & these registers are accessed in the procedure to process the data.<br />CODE SEGMENT<br />MOV AL, DATA<br />CALL PRO1<br />PRO1 PROC NEAR<br />MOV INPUT, AL<br />RET<br />PRO1 ENDP<br />CODE ENDS<br />60. What is recursive procedures<br />A recursive procedure is a procedure, which calls itself. Recursive procedures are<br />used to work with complex data structures called trees. If the procedure is called with<br />N=3, then the N is decremented by 1 after each procedure CALL and the procedure is<br />called until N=0.<br />61. What are libraries<br />Library files are collection of procedures that can be used in other programs. These<br />procedures are assembled and compiled into a library file by the LIB program. The<br />library file is invoked when a program is linked with linker program. when a library file<br />is linked only the required procedures are copied into the program. Use of library files<br />increase s/w reusability & reduce s/w development time.<br />62. What are Macros<br />Macro is a group of instruction. The macro assembler generates the code in the<br />program each time where the macro is called. Macros are defined by MACRO & ENDM<br />directives. Creating macro is similar to creating new opcodes that can be used in the<br />program<br />INIT MACRO<br />MOV AX, data<br />MOV DS<br />MOV ES, AX<br />ENDM<br />63. How do 8086 interrupts occur<br />An 8086 interrupt can come from any of the following three sources<br />• External signals<br />• Special instructions in the program<br />• Condition produced by instruction<br />64. What are the 8086 interrupt types<br />Dedicated interrupts<br />• Type 0: Divide by zero interrupt<br />• Type 1: Single step interrupt<br />• Type 2:Non maskable interrupt<br />• Type 3: Breakpoint<br />• Type 4: Overflow interrupt<br />Software interrupts<br />• Type 0-255<br />65. What is interrupt service routine<br />Interrupt means to break the sequence of operation. While the CPU is executing a<br />program an interrupt breaks the normal sequence of execution of instructions & diverts<br />its execution to some other program. This program to which the control is transferred is<br />called the interrupt service routine.<br />66. Define BIOS<br />The IBM PC has in its ROM a collection of routines, each of which performs some<br />specific function such as reading a character from keyboard, writing character to CRT.<br />This collection of routines is referred to as Basic Input Output System or BIOS.<br />67. Explain PUBLIC<br />For large programs several small modules are linked together. In order that the<br />modules link together correctly any variable name or label referred to in other modules<br />must be declared public in the module where it is defined. The PUBLIC directive is used<br />to tell the assembler that a specified name or label will be accessed from other modules.<br />Format PUBLIC Symbol.<br />68. Explain DUP<br />The DUP directive can be used to initialize several locations & to assign values to<br />these locations. Format Name Data_Type Num DUP (value)<br />Example TABLE DW 10 DUP (0). Reserves an array of 10 words of memory and<br />initializes all 10 words with 0. array name is TABLE.<br />69. Compare Procedure & Macro<br />Procedure Macro<br />Accessed by CALL & RET instruction Accessed during assembly with name given<br />during program execution to macro when defined<br />Machine code for instruction is put only once<br />in the memory<br />Machine code is generated for instruction<br />each time when macro is called<br />With procedures less memory is required With macro more memory is required<br />Parameters can be passed in registers,<br />memory locations or stack<br />Parameters passed as part of statement which<br />calls macro<br />70. What is the purpose of segment registers in 8086?<br />There are 4 segment registers present in 8086. They are<br />1. Code Segment (CS ) register<br />2. Data Segment (DS ) register<br />3. Stack Segment (SS ) register<br />4. Extra Segment (ES ) register<br />The code segment register gives the address of the current code segment. ie.<br />It will points out where the instructions, to be executed, are stored in the memory.<br />The data segment register points out where the operands are stored in the<br />memory.<br />The stack segment registers points out the address of the current stack, which<br />is used to store the temporary results.<br />If the amount of data used is more the Extra segment register points out<br />where the large amount of data is stored in the memory.<br />71. Define pipelining?<br />In 8086, to speedup the execution of program, the instructions fetching and<br />execution of instructions are overlapped each other. This technique is known as<br />pipelining.<br />In pipelining, when the n th instruction is executed, the n+1 th instruction is<br />fetched and thus the processing speed is increased.<br />72. Discuss the function of instruction queue in 8086?<br />In 8086, a 6-byte instruction queue is presented at the Bus Interface Unit<br />(BIU). It is used to prefetch and store at the maximum of 6 bytes of instruction<br />code from the memory. Due to this, overlapping instruction fetch with instruction<br />execution increases the processing speed.<br />73. What is the maximum memory size that can be addressed by 8086?<br />In 8086, an memory location is addressed by 20 bit address and the address<br />bus is 20 bit address and the address bus is 20 bits. So it can address up to one mega<br />byte (2^20) of memory space.<br />74. What is the function of the signal in 8086?<br />BHE signal means Bus High Enable signal. The BHE signal is made low when<br />there is some read or write operation is carried out. ie . When ever the data bus of<br />the system is busy i.e. whenever there is some data transfer then the BHE signal is<br />made low.<br />75.What are the predefined interrupts in 8086?<br />The various predefined interrupts are,<br />DIVISION BY ZERO (type 0) Interrupt.<br />SINGLE STEP (type 1) Interrupt.<br />NONMASKABLE (type2) Interrupt.<br />BREAK POINT (type 3) Interrupt.<br />OVER FLOW (type 4) Interrupt.<br />76. What are the different flag available in status register of 8086?<br />There are 6 one bit flags are present. They are,<br />AF - Auxiliary Carry Flag<br />CF - Carry Flag<br />OF - Overflow Flag<br />SF - Sign Flag<br />PF - Parity Flag<br />ZF - Zero Flag<br />77.

How single stepping can be done in 8086?<br />By setting the Trace Flag (TF) the 8086 goes to single-step mode. In this mode, after<br />the execution of each instruction s 8086 generates an internal interrupt and by writing<br />some interrupt service routine we can display the content of desired registers and<br />memory locations. So it is useful for debugging the program.<br />79. State the significance of LOCK signal in 8086?<br />If 8086 is working at maximum mode, there are multiprocessors are<br />present. If the system bus is given to a processor then the LOCK signal is made<br />low. That means the system bus is busy and it cannot be given of any other<br />processors. After the use of the system bus again the LOCK signal is made high.<br />That means it is ready to give the system bus to any processor.<br />80.

The REPEAT defines the start of the loop & UNTIL the end of<br />the loop. UNTIL has a condition when the condition is true the loop is terminated<br />86. What is multiprogramming?<br />If more than one process is carried out at the same time, then it is know as<br />multiprogramming. Another definition is the interleaving of CPU and I/O<br />operations among several programs is called multiprogramming.<br />To improve the utilization of CPU and I/O devices, we are designing to<br />process a set of independent programs concurrently by a single CPU.<br />This technique is known as multiprogramming<br />87.

For example, a<br />computer may communicate with a terminal in this mode. When the terminal sends data<br />(i.e. terminal is sender). The message is received by the computer (i.e the computer is<br />receiver). However, it is not possible to transmit data from the computer to terminal and<br />from terminal to the computer simultaneously.<br />93.What are the various programmed data transfer methods?<br />ii) Synchronous data transfer<br />iii) Asynchronous data transfer<br />iv) Interrupt driven data transfer<br />94. What is synchronous data transfer?<br />It is a data method which is used when the I/O device and the microprocessor<br />match in speed. To transfer a data to or from the device, the user program issues<br />a suitable instruction addressing the device. The data transfer is completed at the<br />end of the execution of this instruction.<br />95. What is asynchronous data transfer?<br />It is a data transfer method which is used when the speed of an I/O device<br />does not match with the speed of the microprocessor.
