1. 8086 INSTRUCTION FORMATS Compiled by: L. Krishnananda, Assistant Professor, REVA ITM, Bangalore 1 Byte 3 Byte 4 UNIT 2. Instruction Format: The 8086 instruction sizes vary from one to six bytes. Depending on the type of coding, an instruction may have more than one Hexcode Microprocessor and Microcontroller - 8086 Microprocessor - Important Short Questions and Answers: 8086 Microprocessor. A subroutine is a group of instructions written separately from the main program to perform a function that occurs repeatedly in the main program. However, 8086 registers were more specialized than in most contemporary minicomputers and are also used The 8086 provides dedicated instructions for copying strings of bytes. As instructions vary from one to six bytes, fetch and execution are made concurrent and decoupled into separate 28. How many clock pulses required to load 4-bit SIPO register and transfer the data to a. 38. The 8085 instruction cycle consists of one to five machine cycles.The first machine cycle of each instruction cycle is always 47. 8086 instructions varied from - to - bytes ? However, 8086 registers were more specialized than in most contemporary minicomputers and are also used implicitly by some instructions. As instructions vary from one to six bytes, fetch and execution are made concurrent and decoupled into separate units (as it remains in today's x86 Complete 8086 instruction set. Quick reference Some instructions generate exactly the same machine code, so disassembler may have a problem decoding to your original code. 4-byte address may be entered in this form: 1234h:5678h, first value is a segment second value is an offset (this is a As instructions are explained, simple applications are presented to illustrate the operation of the Chapter 15 shows how to interface small systems to the personal computer through the use of the parallel A complete listing of all 8086-Pentium 4 and Core2 instructions, including many example Arithmetic Instructions are the instructions which perform basic arithmetic operations such as addition, subtraction and a few more. Unlike in 8085 microprocessor, in 8086 microprocessor the destination operand need not be the accumulator. Following is the table showing the list of arithmetic The 8086 instruction sizes vary from one to six bytes. Depending on the type of coding, an instruction may have more than one Hexcode, (not unique as in 8085) The OP code field occupies 6-bits.It defines the operation to be carried out by the instruction. Register Direct bit (D) occupies one bit. In 8086, bytes at even addresses come in on the low half of the data bus (bit 0-7) and bytes at odd address come in on upper half of the The BIU contains the circuit for physical calculations and a pre-coding instruction byte queue and it makes the bus signal available for external interfacing of devices. The 8086 processors were 16 bit but had 20 bit address buses to allow for accessing more memory (up to 1MB or 2^20). How? Each bit is typically either a flag representing a condition of the result of the most recent arithmetic or logical instruction, or else a control flag used to vary the way the The 8086 processors were 16 bit but had 20 bit address buses to allow for accessing more memory (up to 1MB or 2^20). How? Each bit is typically either a flag representing a condition of the result of the most recent arithmetic or logical instruction, or else a control flag used to vary the way the However, 8086 registers were more specialized than in most contemporary minicomputers and are The data block is copied one byte at a time, and the data movement and looping logic utilizes 16-bit As instructions vary from one to six bytes, fetch and execution are made concurrent and decoupled Complete 8086 instruction set. Page 1 of 53. 4-byte address may be entered in this form: 1234h:5678h, first value is a. 8086 instructions. 8086 instructions. Page 42 of 53. shift all bits left, the bit that goes off is set to CF and previous value of CF is inserted to the right-most position. ? 8086 instructions vary from 1 to 6 bytes. ? Therefore fetch and execution are taking place concurrently in order to improve the performance of the microprocessor. ? Most of the processor instructions use 16-bit pointers the processor can effectively address only 64 KB of memory.
