Hi,

I am developing apps on a Xilinx zynq board. I do need to run a JPEG compression/decompression benchmark for FreeRTOS, would you please help me with any available benchmark?

Thanks in advance,
Nakisa

Computationally intensive operations, like image compression, really don’t depend on the OS for the sort of processors that FreeRTOS is targeted, so it isn’t something that should really be the subject of a benchmark. All it would measure is the level of “overhead” in the OS, which is very dependent on application.

On bigger machines, designed for multi-cored processors, it might make some sense, assuming you have a multi-threaded version of the compression algorithm. FreeRTOS is not really designed for a multi-cored processor, so this isn’t applicable.
