2.8.2

Instructions and Pipeline Processing

The operands in the table below indicate the following meaning.

#IMM: Immediate

Rs, Rs2, Rd, Rd2, Ri, Rb: General-purpose register, CR: Control register

2.8.2.1

Instructions Converted into Single Micro-Operation and Pipeline Processing

The table below lists the instructions that are converted into a single micro-operation. The number of cycles in the table

indicates the number of cycles during no-wait memory access.

Note 1. The number of cycles for the dividing instruction varies according to the divisor and dividend.

Note 2. For the number of cycles for throughput and latency, see section 2.8.3, Calculation of the Instruction Processing Time.
