| − | The '''SuperH''' (or '''SH''') is a microprocessor 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.

| − | The SH-5 design added a SIMD Instuction Set called SHmedia and also supports the SHcompact instruction set, equivalent to the user-mode parts of the SH-4 instruction set. This is similar to the Thumb Instruction Set of ARM architecture.

| − | The older designs are now supported and sold by [http://www.renesas.com/ Renesas].

| − | The family includes:
| |
| − | | |
| − | * SH-1 - 32-bit with maximum of 20MHz (As used on [[Sega Saturn]] to control the CD-drive and to check the Copy Protection on the game's CD)
| |
| − | * SH-2 - 32-bit with up to 28.7MHz (As used in the [[Sega Saturn]])
| |
| − | * SH-3 - 32-bit with up to 200MHz. This spring introduced a Memory_management_unit to the SH Family (As used in many [[Windows CE]] devices)
| |
| − | * SH-4 - 32-bit dual-issue core with a 128-bit vector FPU (As used in the [[Dreamcast]] and on some Sega Arcade Machines such as the Naomi and Naomi 2)
| |
| − | * SH-5 - 64-bit core with a 128-bit vector FPU (64 32-bit registers) and an integer unit which includes the SIMD support and 63 64-bit registers. (The 64th register is hard-wired to zero.)
