MCU requirement for using FreeRTOS
Posted by Nobody/Anonymous on February 2, 2005
I am new to FreeRTOS. May I know if there is any recommended requirements of the MCU speed when using FreeRTOS? Actually I am going to port to Samsung S3C826A, 8-bit mcu of around 1~2 MIPS max. Is this chip affordable to RTOS?

MIPS values do not really allow one processor speed to be compared directly with another although 1-2 MIPS does sound slow.
The FreeRTOS can be used in a number of different ways with varying processing overheads. It is unlikely that your device will be suitable for a fully preemptive solution but then with this chip it is doubtful that the application would warrant it anyway.
With a low tick frequency and cooperative scheduling the kernel can still simplify your design with very little overhead. See the
pages for an example.
