Section 4 Pipelining
4.3
Instruction execution cycles are summarized in table 4.4. Instruction Group in the table 4.4
corresponds to the category in the table 4.2. Penalty cycles due to a pipeline stall are not
considered in the issue rates and execution cycles in this section.
1. Issue Rate
Rev. 2.00 May 22, 2009 Page 94 of 1982
REJ09B0256-0200
2. Execution Cycles
E.g. MAC.W instruction
FPU instruction
E.g. FMUL instruction
E.g. FDIV instruction
Execution cycles indicates the cycle counts an instruction occupied the pipeline based on the next rules.
CPU instruction
E.g. AND.B instruction
Issue rates indicates the issue period between one instruction and next instruction.
E.g. AND.B instruction
E.g. MAC.W instruction
