8.3
The SH-2A/SH2A-FPU is a 2-ILP (2-Instruction-Level-Parallelism) super-scalar pipelining
microprocessor. When two instructions are in the ID stage, two instructions can be executed
simultaneously (see figure 8.6).
However, parallel execution is not possible in the following cases:
• When resource contention occurs (described in 8.3.1)
• When waiting for the result of a previously issued instruction (described in 8.3.2)
• When register contention or flag contention occurs (described in 8.3.3)
• When a multi-cycle instruction is executed as a preceding instruction (described in 8.3.4)
• When a 32-bit instruction is executed as a preceding instruction (described in 8.3.5)
• In the case of an instruction that uses FPSCR, an FPU instruction, or an FPU-related CPU
• Delayed unconditional branch instruction at which a branch occurs, and delay slot (described
When IF stages are completed for two instructions without the occurrence of such contention, the
SH-2A/SH2A-FPU can perform parallel execution of the two instructions.
The above cases are described in the following subsections. Terms used in the descriptions are as
follows:
• Preceding instruction: Earlier instruction in the same slot
• Succeeding instruction: Later instruction in the same slot
• Previously issued instruction: Generic term for an instruction that has already been issued
