Operating Systems

Overview

In embARC OSP, FreeRTOS is adopted to provide OS kernel service. An optimized DesignWare® ARC® processors port is provided in os/freertos/portable.

FreeRTOS is the market-leading real-time operating system (or RTOS), and the de-facto standard solution for microcontrollers and small microprocessors.

• Provides a single and independent solution for many different architectures and development tools.

• Feature rich and is still undergoing continuous active development.

• Minimal ROM, RAM, and processing overhead. Typical RTOS kernel binary image is 6K to 12K bytes.

• Very simple. The core of the RTOS kernel is contained in only three C files. The majority of the many files included in the .zip file download relate only to the numerous demonstration applications.

• Truly free for use in commercial applications.

• Comes with a porting, platform development, or application development service if required.

• Is well established with a large and ever growing user base.

• Provides ample documentation.

• Highly scalable, simple, and easy to use.

Note

It’s also possible to integrate other RTOS into embARC OSP
