It is a bit p. It provides 14, 16 -bit registers. Word size is 16 bits and double word size is 4 bytes. It can prefetches up to 6 instruction bytes from memory and queues them in order to speed up instruction execution. A 40 pin dual in line package. The BIU performs all bus operations such as instruction fetching, reading and writing operands for memory and calculating the addresses of the memory operands. The instruction bytes are transferred to the instruction queue.

Mar 29,  · String Manipulation Instructions Instruction Set 82 Microprocessor String: Sequence of bytes or words instruction set includes instruction for string movement, comparison, scan, load and store. REP instruction prefix: used to repeat execution of string instructions String instructions end with S or SB or SW. INSTRUCTION SET DATA TRANSFER INSTRUCTIONS MOV – MOV Destination, Source The MOV instruction copies a word or byte of data from a specified source to a specified destination. The destination can be a register or a memory location. The source can be a register, a memory location or an immediate nikeairmaxoutlet.us Size: KB.

Real time means the task required by the application must be completed before any other input to the program that will alter its operation can occur For example the device service routine which controls the operation of the floppy disk drive is a good example that is usually written in assembly language. Mnemonic Meaning Format Operation Flags affected. DX AX 2. The highest bit position is filled with a zero. First Instruction Call subroutine A Next instruction.

Return Call subroutine A Next instruction. Information required to return back to the main program such as IP and CS are saved on the stack. This is the return RET instruction. If operands is present, it is added to the contents of SP. CX must be preloaded with a count that represents the number of times the loop is to be repeat. LOOP instruction does not affect any flags. It is achieved segment to another. Conditional Jump instructions in are just 2 bytes long. Jumps based on Jumps based on a single flag more than one flag.

Otherwise the next instruction is executed. Flags affected : None. Requirement Then do this! Above and Below used for comparing Unsigned nos. Greater than and less than used with signed numbers. All Intel microprocessors use this convention. Direct Jump Indirect Jump common uncommon. Backward jump: Assembler knows the quantum of jump. Assembler reserves 3 bytes for the forward jump instruction. CSH : forward jump. Near Indirect Jump is uncommon. Instruction length: 2 or more bytes Range: complete segment.

It is a 5 byte instruction 1 byte opcode EAH 2 byte offset value 2 byte segment value. Instruction length depends on the way jump location is specified It can be a minimum of 2 bytes. Instruction length is a minimum of 2 bytes. It depends on the way jump location is specified. The will enter a halt state. NOP instruction this instruction simply takes up three clock cycles and does no processing. After this, it will execute the next instruction.

This instruction is normally used to provide delays in between instructions. ESC instruction whenever this instruction executes, the microprocessor does NOP or access a data from memory for coprocessor. This instruction passes the information to math processor. Six bits of ESC instruction provide the opcode to coprocessor. The co-processor will treat normal instructions as NOP. Floating point instructions are executed by and during this will be in WAIT.

This prefix makes sure that during execution of the instruction, control of system bus is not taken by other microprocessor. This is to share the common resources. Each processor will take control of this bus only when it needs to use common resource.

This signal will be made active during this instruction and it is used by the bus control logic to prevent others from taking the bus. WAIT instruction this instruction takes to an idle condition. The CPU will not do any processing during this.

On valid interrupt, ISR is executed and processor enters the idle state again. Learn more about Scribd Membership Home. Read free for days Sign In. Much more than documents.
