Renesas Technology original architecture
32-bit internal data bus
General-register files:
⎯ Sixteen 32-bit general registers (eight 32-bit shadow registers)
⎯ Seven 32-bit control registers
⎯ Four 32-bit system registers
RISC-type instruction set (upward compatibility for the SH-1, SH-2, SH-3
and SH-4 processors)
⎯ Instruction length: 16-bit fixed length for improved code efficiency
⎯ Load/store architecture
⎯ Delayed branch instructions
⎯ Conditional instruction execution
⎯ Instruction-set design based on the C language
Super-scalar architecture covering both the FPU and CPU provides for
the simultaneous execution of any two instructions
Instruction-execution time: Two instructions per cycle (max.)
Virtual address space: 4 Gbytes
Address-space identifiers (ASID): 8 bits, for 256 virtual address spaces
Internal multiplier
Eight-stage pipeline
