WebApr 16, 2024 · x86 Assembly/SSE. SSE stands for Streaming SIMD Extensions. It is essentially the floating-point equivalent of the MMX instructions. The SSE registers are 128 bits, and can be used to perform operations on a variety of data sizes and types. Unlike MMX, the SSE registers do not overlap with the floating point stack. WebASK AN EXPERT. Engineering Computer Engineering CMPS The CMPS instruction compares two strings. This instruction compares two data items of one byte, word or doubleword, pointed to by the DS:SI and ES:DI registers and sets the flags accordingly. You can also use the conditional jump instructions along with this instruction.
