Processor Data Sheet
Preliminary Information
Short and long decodes are processed completely within the
decoders. Vector decodes are started by the decoders and then
completed by fetched sequences from an on-chip ROM. After
decoding, the RISC86 operations are delivered to the scheduler
for dispatching to the execution units.
Scheduler/Instruction Control Unit.
The centralized scheduler or
buffer is managed by the Instruction Control Unit (ICU). The
ICU buffers and manages up to 24 RISC86 operations at a time.
This equals from 6 to 12 x86 instructions. This buffer size (24) is
perfectly matched to the processor’s six-stage RISC86 pipeline
and seven parallel execution units. The scheduler accepts as
many as four RISC86 operations at a time from the decoders.
The ICU is capable of simultaneously issuing up to six RISC86
operations at a time to the execution units. This consists of the
following types of operations:
I
Memory load operation
Memory store operation
Complex integer or MMX register operation
Simple integer register operation
Floating-point register operation
Branch condition evaluation

Registers.
The scheduler uses 48 physical registers that are
contained within the RISC86 microarchitecture when managing
the 24 RISC86 operations. The 48 physical registers are located
in a general register file and are grouped as 24 general
registers, plus 24 renaming registers. The 24 general registers
consist of 16 scratch registers and eight registers that
correspond to the x86 general purpose registers—EAX, EBX,
ECX, EDX, EBP, ESP, ESI and EDI.
Branch Logic.
The mobile AMD-K6 processor is designed with
highly sophisticated dynamic branch logic consisting of the
following:
I
Branch history/Prediction table
Branch target cache
Return address stack
I
I
The mobile AMD-K6 processor implements a two-level branch
prediction scheme based on an 8192-entry branch history table.
The branch history table stores prediction information that is
