GNU Tools for ARC® Processors

Quality Open Source Software for ARC® Multimedia Subsystems and IP Cores

The GNU development effort uses an open development environment and supports many platforms, including ARC processors. Many developers around the world have come to utilize GNU based tools in C/C++ software development for embedded applications because of their quality, performance, and standard interface across multiple target CPUs.

Because of the importance of open source tools in embedded software, ARC invests in open source projects, such as GNU and Linux, on ARC processors. ARC ensures there is up-to-date open source GNU tools support for all of its processors and is continuously updating and optimizing the ARC GNU tools for ARC processors and the ARCompact instruction set architecture. Furthermore, ARC is working with the MilePost project which is funded by the European Union Information Society Technologies (IST) . The overall objective of this project is to develop compiler technology that can automatically learn how to best optimise programs for re-configurable heterogeneous embedded processors, dramatically reducing the time to market of re-configurable systems.

ARC GNU Tools offer all of the benefits of open source tools, including complete source code and a large install base. ARC GNU Tools include the GCC compiler and GDB debugger as well a number of utilities and libraries that make up a complete software tool chain. Because source code for the GNU tool chain is always available the ARC GNU Tools are configurable; allowing tailoring, customization, and expansion of the tools, libraries, debugger, and board support to meet user-specific requirements

ARC GNU Tools are provided in source packages than can be built to run on Linux and Windows host platforms (running on Windows requires using a Cygwin environment). ARC GNU Tools are available for software developers using ARC configurable processor IP cores, ARC Media Subsystems and for ARC-based® processors sold by ARC licensees.

Download GNU Tools for ARC Processors

Members of the Open Source Software Program can receive disitributions of GNU tools for ARC processors directly from ARC.

ARC's partner Codito also maintains an independent version of the GNU tools including previous versions of the GNU tool chain - these distributions can be accessed at: http://www.arc-linux.org.
