SuperH (or SH) is a 32-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Hitachi. It is implemented by microcontrollers and microprocessors for embedded systems. The SH-3 and SH-4 architectures support both big-endian and little-endian byte ordering (they are bi-endian).
