SuperH

The SuperH (SH) is a microprocessor/controller architecture. It is basically a 32-bit load/store RISC core design, with a 16-bit instruction set, but 32-bit register length and data paths. This gives high code density; in the 1990s, memory was very expensive. It was first developed by Hitachi in the early 1990s. They were developing a full set of instruction set upward compatible cores. The first, SH-1 and SH-2 were used in the Sega Saturn and 32X game consoles, and then later in many other microcontrollers used in many other embedded systems. Many processors and controllers are based on this core family. It is used in many embedded systems.
