2.1
Superpipeline
The Superpipeline is composed of Integer, Multiply-Accumulate (MAC), and memory pipes.
The Integer pipe has seven stages:
Branch Target Buffer (BTB)/Fetch 1
Fetch 2
Decode
Register File/Shift
ALU Execute
State Execute
Integer Writeback
The Memory pipe has eight stages:
the first five stages of the Integer pipe (BTB/Fetch 1 through ALU Execute)
. . . then finish with Memory stages:
Data Cache 1
Data Cache 2
Data Cache Writeback
The MAC pipe has six to nine stages:
the first four stages of the Integer pipe (BTB/Fetch 1 through Register File/ Shift)
. . . then finish with MAC stages:
MAC1
MAC2
MAC3
MAC4
Register Writeback
The MAC pipe supports a data-dependent early terminate where stages MAC2, MAC3, and/or
MAC4 are by-passed.
Deep pipes promote high instruction execution rates only when a means exists to successfully
predict the outcome of branch instructions. The Branch Target Buffer provides such a means.
