Features of the SH7032 and SH7034 Microcomputers
Description
Original Renesas architecture
32-bit internal data paths
General-register machine:
Sixteen 32-bit general registers
Three 32-bit control registers
Four 32-bit system registers
RISC-type instruction set:
Instruction length: 16-bit fixed length for improved code efficiency
Load-store architecture (basic arithmetic and logic operations are
Delayed unconditional branch instructions reduce pipeline disruption
