Completion unit
— As many as 14 instructions allowed in 14-entry completion queue (CQ)
— In-order retirement of as many as two instructions per cycle
— Completion and refetch serialization control
— Synchronization for all instruction flow changes—interrupts, mispredicted branches, and
Issue queues
— Two-entry branch instruction issue queue (BIQ)
— Four-entry general instruction issue queue (GIQ)
Branch unit—The branch unit (BU) is an execution unit and is distinct from the BPU. It executes
(resolves) all branch and CR logical instructions.
Two simple units (SU1 and SU2)
— Add and subtract
— Shift and rotate
— Logical operations
— Support for 64-bit SPE instructions in SU1
Multiple-cycle unit (MU)—The MU is shown in
The MU has the following features:
— Four-cycle latency for all multiplication, including SPE integer and fractional multiply
— Variable-latency divide: 4, 11, 19, and 35 cycles for all integer divide instructions. If rA or rB
context-synchronizing instructions
instructions and embedded scalar and vector floating-point multiply instructions
is zero, floating-point divide instructions take 4 cycles; all others take 29. Note that although
most divide instructions take more than 4 cycles to execute, the MU allows subsequent
multiply instructions to execute through all four MU stages in parallel with the divide.
