Abstract
Multicore processors are ubiquitous. Their use in embedded systems is growing rapidly, and given the constraints on uniprocessor clock speeds, their importance in meeting the demands of increasingly processor-intensive embedded applications cannot be understated. To harness this potential, system designers need to have available to them embedded operating systems with built-in multicore support for widely available embedded hardware. This paper documents our experience of adapting FreeRTOS, a popular embedded real-time operating system, to support multiple processors. A working multicore version of FreeRTOS that is able to schedule tasks on multiple processors as well as provide full mutual-exclusion support for use in concurrent applications is presented. Mutual exclusion is achieved in an almost completely platform-agnostic manner, preserving one of FreeRTOS's most attractive features: portability. Copyright © 2013 John Wiley & Sons, Ltd.
