QEMU is a generic and open source machine and user space emulator and virtualizer. QEMU is capable of emulating a complete machine in software without any need for hardware virtualization support.  Synopsys has implemented support for ARCv2 EMx, HS3x and HS4x processors; and ARCv3 HS5x and HS6x processors.

GNU/Linux Toolchain

GNU Toolchain for Embedded Linux on ARC® Processors. Includes support for ARCv1 (ARC750, ARC770), ARCv2 (ARC HS38, ARC HS38x2 and ARC HS38x4) and ARCv3 (ARC HS5x, ARC HS6x) architectures. Source code available from upstream Linux kernel repositories at kernel.org.

Linux Kernel

The Linux Kernel, with support for ARC Processors. Includes support for ARCv1 (ARC750, ARC770), ARCv2 (ARC HS38, ARC HS38x2 and ARC HS38x4) and ARCv3 (ARC HS5x/HS6x) architectures. Source code available from upstream Linux kernel repositories at kernel.org

Automotive Grade Linux

Automotive Grade Linux is a collaborative open source project that is bringing together automakers, suppliers and technology companies to accelerate the development and adoption of a fully open software stack for the connected car. With Linux at its core, AGL is developing an open platform from the ground up that can serve as the de facto industry standard to enable rapid development of new features and technologies. This project contains required components and instructions and build and run AGL on ARC HS Processors. A prebuilt demonstration image for the ARC HSDK platform is also available.

It is designed to provide a unified platform for DesignWare® ARC® processors users by […]


OpenThread is a Thread Certified Component an open-source implementation of the Thread networking protocol. Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.


Developed in partnership with the world's leading chip companies over a 12 year period, FreeRTOS is the market leading real time operating system (or RTOS), and the de-facto standard solution for microcontrollers and small microprocessors. Support for FreeRTOS on ARC Processors is provided under the embARC OSP project.

TencentOS tiny

TencentOS tiny is a real-time operating system for the Internet of Things. It features low power consumption, low resource consumption, modularity, security and reliability, and can effectively improve the development efficiency of IoT terminal products. The TencentOS tiny project is sponsored by Tencent.

Contiki OS

Contiki is an open source operating system for the Internet of Things. Contiki connects tiny low-cost, low-power microcontrollers to the Internet. Support for Contiki OS on ARC Processors is provided under the embARC OSP project.


RIOT is a free, open source operating system developed by a grassroots community gathering companies, academia, and hobbyists, distributed all around the world. RIOT implements all relevant open standards supporting an Internet of Things that is connected, secure, durable, and privacy-friendly. A port to the ARC EM Processor has been contributed by the community.

Toppers ASP

TOPPERS(Toyohashi OPen Platform for Embedded Real-time Systems)Project, based on ITRON, is aimed at base software for use in embedded systems. The TOPPERS/ASP kernel is the foundation for the new generation of TOPPERS real-time kernels that follow the TOPPERS new generation kernel specification. ASP (Advanced Standard Profile) has been developed by extending and improving TOPPERS/JSP, a real-time kernel based on the standard profile of μITRON4.0. Support for the ARC architecture is available below.
