The SuperH (or SH) is a family of microprocessors, originally developed by Hitachi during the 1990s as the successor to the H8 family, and now supported by Renesas. They were notable for their time as being capable, yet relatively cheap units with low power consumption.
The SuperH family was introduced in 1992. It was one of the first CPU processors to support an efficient Thumb-like instruction set (with single-cycle instructions) and hardware support for multiply–accumulate (MAC) operations (two cycles per MAC operation). Between 1994 and 1996, 35.1 million SuperH devices were shipped worldwide, with a 32% share of the microprocessor market in 1996.
Sega has used SuperH chips as the central processing unit for a number of video game consoles and arcade machines:
SH-3 and SH-5 chips also belong to the family, but were never utilised by Sega. Towards the early 2000s, the family had perhaps out-lived its potential in video gaming, however the technology continues to see widespread use in other forms of electronics.
