SuperH - Models

Models

The family of SuperH CPU cores includes:

  • SH-1 - used in microcontrollers for deeply embedded applications (CD-ROM drives, major appliances, etc.)
  • SH-2 - used in microcontrollers with higher performance requirements, also used in automotive such as engine control units or in networking applications, and also in video game consoles, like the Sega Saturn. The SH-2 has also found home in many motor control applications, including Subaru, Mitsubishi, and Mazda.
  • SH-2A - The SH-2A core is an extension of the SH-2 core including a few extra instructions but most importantly moving to a superscalar architecture (it is capable of executing more than one instruction in a single cycle) and two five-stage pipelines. It also incorporates 15 register banks to facilitate an interrupt latency of 6 clock cycles. It is also strong in motor control application but also in multimedia, car audio, powertrain, automotive body control and office + building automation
  • SH-DSP - initially developed for the mobile phone market, used later in many consumer applications requiring DSP performance for JPEG compression etc.
  • SH-3 - used for mobile and handheld applications such as the Jornada, strong in Windows CE applications and market for many years in the car navigation market
  • SH-3-DSP - used mainly in multimedia terminals and networking applications, also in printers and fax machines
  • SH-4 - used whenever high performance is required such as car multimedia terminals, video game consoles, or set-top boxes
  • SH-5 - used in high-end multimedia applications
  • SH-X - mainstream core used in various flavours (with/without DSP or FPU unit) in engine control unit, car multimedia equipment, set-top boxes or mobile phones
  • SH-Mobile - SuperH Mobile Application Processor; designed to offload application processing from the baseband LSI

Famous quotes containing the word models:

    “The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
    —Samuel Butler (1835–1902)

    “Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
    —Marshall McLuhan (1911–1980)

    “The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.”
    —Woodrow Wilson (1856–1924)
