Processors

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.

ARC

The ARC
770D
32-bit RISC processor from the DesignWare ARC Processor IP
family is optimized for running
Linux. The latest version of ARC Linux is available from
kernel.org and older versions as well as the GNU
toolchain and several other packages like U-boot and Buildroot for ARC
are available via
GitHub.

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 processors that include a memory management unit (MMU), and can
    run standard Linux
  • ARM processors without MMU. These can run a modified version of
    Linux called uClinux ( http://uclinux.org/ ),
    enabling Linux to run on MMUless platforms or embedded processors
    with memory protection unit (MPU). These include ARM processors such
    as ARM7TDMI, ARM1156T2(F)-S or ARM Cortex-R4(F) for instance.

Please note that because of security considerations for MMU-less
processors, it is unwise to use them when 3rd-party or untrusted code
will be running on the device. For locked-down, single function devices,
MMU-less processors may be appropriate. They are usually less expensive
than processors with MMU.

Some major ARM platforms/SOCs are:

MIPS

Information about MIPS processor architecture can be found
here. For the Linux port information can be found
here.

Processors based on MIPS architecture include

  1. TX System
    RISC     from
    Toshiba.
  2. MSP series of processor
    from PMC Sierra.

Renesas SuperH Overview

SuperH is an embedded RISC developed for high cost-performance,
miniaturization, and performance per unit of power consumption (MIPS/W).
We are developing CPU cores for a wide range of applications and
functions and have many products available. Our product lines include a
series with the SH-2 as the CPU core and on-chip large-capacity flash
memory and peripheral functions such as timer, serial I/O, and AD
converter, and a series with the SH-3 or SH-4 as the CPU core, which
achieves high-speed data processing and is equipped with cache and MMU.
Additionally, there is lineup of series with the SH2-DSP or SH3-DSP as
the CPU core, which have full DSP functions and an emphasis on
multimedia and communications processing. Currently available products
also have lots of features, such as low power modes, low power
consumption, and small size. Various versatile operating systems and
development tools have been improved, allowing for more efficient
development.

  • Native Tools (Shell, commands and libraries) which provide a standard Linux development environment that runs on the target system.
  • U-Boot - Firmware that can be easily ported to new boards and processors.
  • Linux - Kernel including the complete source-code with all device drivers, board-support functions etc.
  • Xenomai - Real-Time and RTOS Emulation Framework
  • SELF (Simple Embedded Linux Framework) as fundament to build your embedded systems on.

All components of the ELDK are available for free with complete source
code under GPL and other Free Software Licenses. Also, detailed
instructions to rebuild all the tools and packages from scratch are
included.

The ELDK can be downloaded for free from several mirror sites or ordered
on CD-ROM for a nominal charge (99 Euro). To order the CD please contact
office@denx.de
