PPC440 CPU Core Organization
PPC440 CPU
The PPC440 CPU operates on instructions in a dual issue, seven stage pipeline, capable of dispatching
two instructions per clock to multiple execution units and to optional Auxiliary Processor Units (APUs).
The PPC440 core is shown in Figure 2.
Figure 2 - PPC440 Core Block Diagram
The pipeline contains the following stages, as shown in Figure 3:
1.
IFTH – Fetch instructions from instruction cache
2.
PDCD – Pre-decode; partial instruction decode
3.
DISS – Decode/Issue; final decode and issue to units
4.
RACC – Register Access; read from multi-ported General Purpose Register (GPR) file
5.
EXE1/AGEN – Execute stage 1; complete simple arithmetics, generate load/store address
6.
EXE2/CRD – Execute stage 2; multiplex in results from units in preparation for writing into GPR
file, Data Cache access
7.
WB – Writeback; write results into GPR file from integer operation or load operation
