Overview of Linux supported CPU architectures

Linux kernel has some related architectures under the Arch directory in source code:

x86:x86 is an instruction set architecture family;earlier processor names in this series are represented by numbers80x86. Due to the end of "86", includingIntel 8086,80186,80286,80386as well80486, so its architecture is called "x86". The x86 architecture is important for variable instruction length CISC (complex instruction set PC, Complex instruction set computer). ARM:is a 32-bit streamlined instruction set (RISC) processor architecture that is widely used in many embedded system designs. Due to its energy-saving features, the ARM processor is ideal for mobile communications and meets its main design objectives for low cost, high performance, and low power consumption. Alpha:also known as Alpha AXP, is a 64-bit RISC instruction set architecture microprocessor developed by Dec Corporation. SPARC:the name is derived fromExpandable Processor Architecture(ScalablePRocessorARChitecture) is an abbreviation forRISCInstruction Set Schema, first established in 1985 bySolar Micro Systemdesign, but alsoSPARC International Inc.one of the registered trademarks. AVR:Atmel AVRSeries is an improvement-basedHarvard Structure, 8-bit ~32 bitStreamlined instruction Set(reduced instruction Set Computing,risc) ofmicrocontroller. OpenRISC:is a developer working to produce very high-performance open-source RISC CPU.
