From Wikipedia, the free encyclopedia.
The SuperH computer processor family is a CPU architecture. The SuperH core is RISC based and found in a large number of embedded systems.
The SuperH family was first developed by Hitachi as the successor to the H8 Family and was outsourced to the newly-formed SuperH Inc., owned by Hitachi and ST Microelectronics. SuperH Inc now sells the designs of the CPU cores.
Later designs added a SIMD Instuction Set called SHmedia and a more compact instruction set called SHcompact, similar to the Thumb Instruction Set of ARM.
The older designs are now supported and sold by Renesas.
The family includes:
- SH-1 - 32Bit with maximum of 20 MHz
- SH-2 - 32Bit with up to 28.7MHz (Used e.g. in the Sega Saturn))
- SH-3 - 32Bit with up to 200 MHz. This spring introduced a MMU to the SH Family (Used in a lot of Windows CE devices)
- SH-4 - 32Bit Core with a 128Bit Vector FPU (Used e.g. in the Dreamcast)
- SH-5 - 64Bit Core
