NEC V20 and V30 (and possibly other NEC V-series CPUs) always use base 10, and ignore the argument, causing a number of incompatibilities Later Intel's documentation has the generic form too. Original 8086/8088 instructions Original 8086/8088 instruction setĨ086/8088 datasheet documents only base 10 version of the AAD instruction ( opcode 0xD5 0x0A), but any other base will work. The updated instruction set is also grouped according to architecture ( i386, i486, i686) and more generally is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64). Most if not all of these instructions are available in 32-bit mode they just operate on 32-bit registers ( eax, ebx, etc.) and values instead of their 16-bit ( ax, bx, etc.) counterparts. #Opcode sheet for 8086 pdf full#3.6.1.2 SSE4.1 SIMD integer instructionsīelow is the full 8086/8088 instruction set of Intel (81 instructions total).3.6.1.1 SSE4.1 SIMD floating-point instructions.3.4.1 SSE3 SIMD floating-point instructions.3.3.2.2 SSE2 integer instructions for SSE registers only.3.3.2.1 SSE2 MMX-like instructions extended to SSE registers.3.3.1.5 SSE2 shuffle and unpack instructions.3.3.1.2 SSE2 packed arithmetic instructions.3.3.1.1 SSE2 data movement instructions.3.3.1 SSE2 SIMD floating-point instructions.3.1.2.3 MMX instructions added with SSSE3.3.1.2.2 MMX instructions added with SSE2.3.1.2.1 MMX instructions added with MMX+ and SSE.3.1.2 MMX instructions added in specific processors.1.4 Added as instruction set extensions.1.3 Added in specific non-Intel processors. ![]()
