Features of SH7136 and SH7137

Items

Specification

CPU

• Central processing unit with an internal 32-bit RISC (Reduced

Instruction Set Computer) architecture

• Instruction length: 16-bit fixed length for improved code efficiency

• Load-store architecture (basic operations are executed between

registers)

• Sixteen 32-bit general registers

• Five-stage pipeline

• On-chip multiplier: Multiplication operations (32 bits × 32 bits → 64 bits)

executed in two to five cycles

• C language-oriented 62 basic instructions

Note:

Some specifications on slot illegal instruction exception handling

in this LSI differ from those of the conventional SH-2. For details,

see section 5.8.4, Notes on Slot Illegal Instruction Exception

Handling.
