Execution Units
®
The AMD-K6-IIIE+ processor contains ten parallel execution
units—store, load, integer X ALU, integer Y ALU, MMX ALU
(X), MMX ALU (Y), MMX/3DNow! multiplier, 3DNow! ALU,
floating-point, and branch condition. Each unit is independent
and capable of handling the RISC86 operations issued to it.
Table 1 on page 23 details the execution units, functions
performed within these units, operation latency, and operation
throughput.
Note that the integer, MMX, and 3DNow! execution units share
the register X and Y issue pipelines. See “Register X and Y
Pipelines” on page 24.
The store and load execution units are two-stage pipelined
designs.
