Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
Using a CP/M-80 manual as reference, [5] Paterson modeled 86-DOS after its architecture and interfaces, but adapted to meet the requirements of Intel's 8086 16-bit processor, for easy (and partially automated) source-level translatability of the many existing 8-bit CP/M programs; [4] porting them to either DOS or CP/M-86 was about equally ...
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.
x86 (also known as 80x86 [3] or the 8086 family [4]) is a family of complex instruction set computer (CISC) instruction set architectures [a] initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
The VIA/Zhaoxin PadLock instructions are instructions designed to apply cryptographic primitives in bulk, similar to the 8086 repeated string instructions. As such, unless otherwise specified, they take, as applicable, pointers to source data in ES:rSI and destination data in ES:rDI, and a data-size or count in rCX.
Intel designed the 8086 to have its assembly language be similar enough to the 8080, with most instructions mapping directly onto each other, that transpiled 8080 assembly code could be executed on the 8086. [7] The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4, 5, 7, 10, or 11 clock cycles.
A small number of additional instructions. The 80188 was a version with an 8-bit bus. 286 first x86 processor with protected mode including segmentation based virtual memory management. Performance improved by a factor of 3 to 4 over 8086. Included instructions relating to protected mode. The 80286 had a 24-bit address bus.
Version 4.0 of OMF for the 8086 family was released in 1981 under the name Relocatable Object Module Format, [6] [3] [4] and is perhaps best known to DOS users as an .OBJ file. Versions for the 80286 ( OMF-286 ) [ 7 ] [ 8 ] and the 32-bit 80386 processors ( OMF-386 ) [ 9 ] [ 10 ] [ 3 ] were introduced in 1981 and 1985, respectively.
