MMWORD

  • Artikkeli

Used for 64-bit multimedia operands with MMX and SSE (XMM) instructions.

Syntax

MMWORD

Remarks

MMWORD is a type. Prior to MMWORD being added to MASM, equivalent functionality could have been achieved with:

    mov mm0, qword ptr [ebx]

While both instructions work on 64-bit operands, QWORD is the type for 64-bit unsigned integers and MMWORD is the type for a 64-bit multimedia value.

MMWORD is intended to represent the same type as __m64.

Example

    movq     mm0, mmword ptr [ebx]
