Appendix 2.1 32170 Instruction Processing Time
For the M32R, the number of instruction execution cycles in E stage normally represents its
instruction processing time. However, depending on pipeline operation, other stages may affect the
instruction processing time. Especially when a branch instruction is executed, the processing time
in IF (instruction fetch) and D (decode) stages, not just E (execution) stage, must also be taken into
account.
The table below shows the instruction processing time in each pipelined stage of the M32R.
