Hi Experts,
I went through the code flow of CMSIS RTX RTOS. I am excited to know the real engineering done on building the RTX RTOS towards Cortex Microcontroller series. It can be some parameters like task switch time, interrupts latency time, etc. Any white paper document on why the CMSIS RTX RTOS is better than any other RTOS for Cortex processors.
Hi pravinchanm,
Essentially the CMSIS RTX RTOS has the same specifications as the Keil RTX RTOS. These can be found on the Keil web site at...
RTX Real-Time Operating System Specifications
Specifically for the Cortex-M varients, the RTX library for Cortex™-M3/M4 does not disable interrupts. Interrupt latency is the same as without the RTX kernel. Interrupt latency for Cortex™-M0/M1 is <20 cycles
Hopefully this helps!
Thanks,
Ken
