Section 7 Pipeline Operation
MAC
instruction types:
The pipeline has four stages: IF, ID, EX, and MA (figure 7.91). MA is a stage for accessing the
memory and multiplier. MA contends with IF. This makes it the same as ordinary store
instructions. Since the multiplier does contend with the MA, however, the items noted for the
multiplication, Multiply/Accumulate, double-length multiplication, and double-length
multiply/accumulate instructions apply.
RTE Instruction (Common): RTE
The pipeline has five stages: IF, ID, EX, MA, and MA (figure 7.92). The MAs do not contend
with IF. RTE is a delayed branch instruction. The ID of the delay slot instruction is stalled 3 slots.
The IF of the branch destination instruction starts from the slot following the MA of the RTE.
