The SH3 Processor

The SH3 processor at netoogram.com The SuperH processor (SH3) core family was first developed by Hitachi in the early 1990s. Hitachi has developed a complete group of upward compatible instruction set CPU cores. The SH-1 and the SH-2 were used in the Sega Saturn and Sega 32X. These cores have 16-bit instructions for better code density than 32-bit instructions, a benefit at the time as memory was very expensive. A few years later the SH-3 core was added to the SH CPU family; new features included another interrupt concept, a memory management unit (MMU) and a modified cache concept. The SH-3 core also got a DSP extension, then called SH-3-DSP. With extended data paths for efficient DSP processing, special accumulators and a dedicated MAC-type DSP engine, this core was unifying the DSP and the RISC processor world. A derivative was also used with the original SH-2 core (from wikipedia.org).
