VEX Prefix
The VEX prefix (from "vector extensions") and VEX coding scheme are an extension to the x86 and x86-64 instruction set architecture for microprocessors from Intel, AMD and others. Features The VEX coding scheme allows the definition of new instructions and the extension or modification of previously existing instruction codes. This serves the following purposes: * The opcode map is extended to make space for future instructions. * It allows instruction codes to have up to four operands (plus immediate), where the original scheme allows only two operands (plus immediate). * It allows the size of SIMD vector registers to be extended from the 128-bits XMM registers to 256-bits registers named YMM. There is room for further extensions of the register size. * It allows existing two-operand instructions to be modified into non-destructive three-operand forms where the destination register is different from both source registers. For example, instead of (where register ''a'' is change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
