Datasheet - Commercial and Extended Temperature (80200T)
2.1
Superpipeline
The Superpipeline is composed of Integer, Multiply-Accumulate (MAC), and memory pipes.
The Integer pipe has seven stages:
The Memory pipe has eight stages:
. . . then finish with Memory stages:
The MAC pipe has six to nine stages:
. . . then finish with MAC stages:
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.
