SuperH

SuperH (SH ) is a RISC -like processor architecture. It was originally developed by Hitachi. Later, the development of a joint venture between Hitachi and STMicroelectronics, was SuperH Inc., continued. Since the merger of Hitachi 's semiconductor division with Mitsubishi Electric SuperH continues Renesas Electronics.

The architecture is very common in Japan and is used worldwide in many embedded systems, especially in automotive applications. It consumes very little power and is relatively inexpensive. HP Jornada series is based on SH processors.

Overall, there is still five generations.

SH-1

SH -1 is a conventional 32 -bit CPU having a maximum clock speed of 20 MHz. This version was used as a coprocessor in Sega Saturn game console as well as, inter alia, in the ISDN adapter ELSA TanGo 1000 and in analog modem ELSA MicroLink 56k Internet II. There were no further marketing or licensing.

SH-2

The SH-2 corresponds in large parts of the SH-1, except that the SH-2 CPU was clocked at up to 28.7 MHz. She came as the main processor in the Sega Saturn used. A clocked at 23 MHz version came in Sega 32X hardware extension to use. Again, no further marketing or licensing took place. In addition, the SH-2 was among others in the arcade boards Kaneko Super Nova System and Psikyo SH2 used. A well-known game, for example, Strikers 1945 II by Psikyo, which was implemented among others for the PlayStation 1 and Sega Saturn.

In embedded systems cost controller of the SH -2 series are still used today, especially in the automotive sector for engine control.

A further development of the SH- 2 core, the SH -2A core is clocked fast to 200 MHz and today especially in the automotive sector and mobile communications is used.

SH-3

Like their predecessors, the SH-3, a 32 -bit CPU that has been clocked at up to 200 MHz and a memory management unit (English: Memory Management Unit MMU) contains. A special form of SH -3 is the SH3 DSP as SHmobile known. This form is mainly used in mobile phones. This line is now developed and sold or Renesas Technology. Furthermore, the SH3 - DSP ​​is also used as a digital signal processor in the music industry, for example in the Electribe MX the company KORG.

SH-4

The SH -4 is a 32 -bit microprocessor (64- bit when using double-precision micro-instructions ) with a built-in 128 -bit FPU (Floating Point Unit ), which is a vector unit ( VPU ) supplements. The benefit amounts to about 360 MIPS (millions of instructions per second), the floating point unit delivers to the 1.4 billion floating point operations per second ( Giga - FLOPS, short or GFLOPs ). The clocked at around 200 MHz RISC processor served as the CPU in the video game console Sega Dreamcast, the successor to the Sega Saturn. Like the predecessor the SH -4 is used in the automotive industry. For example, one comes clocked at 400 MHz SH-4 in the head unit Audio 50 APS, the Mercedes -Benz C-Class W204 used and clocked at 600 MHz version of the APS - 50 of the E-Class W212 (from 2009).

SH -5

SH -5 was the first 64-bit CPU in the SuperH line. Containing a vector capable of 128-bit FPU.
