Instructions Supported by the AMD-K6® Processor

This section documents all of the x86 instructions supported by

the AMD-K6 processo r. Th e fo ll ow in g tab les show the

instruction mnemonic, opcode, modR/M byte, decode type, and

RISC86 operation(s) for each instruction. Tables 10 through 12

define the integer, floating-point, and MMX instructions,

respectively.

The first column in these tables indicates the instruction

mnemonic and operand types with the following notations:

reg8—byte integer register defined by instruction byte(s) or

bits 5, 4, and 3 of the modR/M byte

mreg8—byte integer register defined by bits 2, 1, and 0 of

the modR/M byte

reg16/32—word and doubleword integer register defined by

instruction byte(s) or bits 5, 4, and 3 of the modR/M byte

mreg16/32—word and doubleword integer register defined

by bits 2, 1, and 0 of the modR/M byte

mem8—byte integer value in memory

mem16/32—word or doubleword integer value in memory

mem32/48—doubleword or 48-bit integer value in memory

mem48—48-bit integer value in memory

mem64—64-bit value in memory

imm8—8-bit immediate value

imm16/32—16-bit or 32-bit immediate value

disp8—8-bit displacement value

disp16/32—16-bit or 32-bit displacement value

disp32/48—doubleword or 48-bit displacement value

eXX—register width depending on the operand size

mem32real—32-bit floating-point value in memory

mem64real—64-bit floating-point value in memory

mem80real—80-bit floating-point value in memory

mmreg—MMX register

mmreg1—MMX register defined by bits 5, 4, and 3 of the

modR/M byte

mmreg2—MMX register defined by bits 2, 1, and 0 of the

modR/M byte
