Here is a list of different processor families, with miscellaneous notes for development information:

See also Hardware Hacking for a list of systems that include these processors.

ARM

See ARM website and the Wikipedia ARM article for information about the ARM architecture and processor family.

From the Linux perspective, there are 2 very different kinds of ARM chips:

  • ARM devices that include a MMU, and can run standard Linux
  • ARM devices without a MMU, which cannot run standard Linux. However, they can run uClinux. The Linux/Microcontroller project is a port of Linux to systems without a Memory Management Unit (MMU), such as the ARM7TDMI and the Microblaze. ( http://uclinux.org/ ). Is it true that the the Linux security permissions system relies on the MMU?

(FIXME: indicate whether or not each chip has a MMU)


Some major ARM platforms/SOCs are:
