What are the types of computer architectures in a CPU?


Embedded CPU architectures

  • ARM'sARM architecture (32-bit)ARM64 (64/32-bit)
  • Atmel's AVR architecture
  • Microchip's PIC architecture
  • Texas Instruments's MSP430 architecture
  • Intel's 8051 architecture
  • Zilog's Z80 architecture
  • Western Design Center's 65816 architecture
  • Hitachi's SuperH architecture
  • Axis Communications' ETRAX CRIS architecture
  • Power Architecture (formerly PowerPC)
  • EnSilica's eSi-RISC architecture

  • Inmos' Transputer architectures

Microcomputer CPU architectures

  • Pre-x86
  • x86Intel's IA-32 architecture, also called x86-32x86-64 with AMD's AMD64 and Intel's Intel 64version of it
  • Motorola's 6800 and 68000 architectures
  • MOS Technology's 6502 architecture
  • Zilog's Z80 architecture
  • Power Architecture (formerly POWER and PowerPC)
  • ARM'sARM[1][2] (32-bit) (previously Advanced RISC Machines' ARM, originally Acorn's RISC Machine) and StrongARM/XScalearchitecturesARM64 (64/32-bit)
  • Renesas RX CPU architecture - Combination of RISC and CISC architectures

Workstation/Server CPU architectures

  • DEC's Alpha architecture
  • HP's PA-RISC architecture
  • Power Architecture (formerly POWER and PowerPC)
  • Intel's Itanium architecture (formerly IA-64)
  • MIPS Computer Systems Inc.'s MIPS architecture
  • Oracle's (formerly Sun Microsystems's) SPARCarchitecture

Mini/Mainframe CPU architectures

  • Burroughs large systems architecture (1961–present) currently supported in the UnisysClearPath/MCP series.
  • IBM's System/360, System/370, ESA/390 and z/Architecture (1964–present)
  • DEC's PDP-8 architecture, the successor PDP-11 architecture, and its final form, the VAXarchitecture
  • UNIVAC 1100/2200 series architecture (currently supported by Unisys ClearPath IX computers)
  • MIL-STD-1750A - the U.S.'s military standard computer
  • AP-101 - the space shuttle's computer

Mixed-core CPU architectures

  • IBM's Cell architecture (a general purpose architecture that uses a POWER4 based core and 8 RISC based co-processors)
  • CAS's Loongson 3
  • Parallax Propeller, a 160 MIPS multicoremicrocontroller with eight 32-bit RISC cores.
