CortexA17 is the most efficient "midrange" processor, and it squarely targets premium smartphones and tablets The Cortex has been widely deployed in that market, but the CortexA17 offers an increase of more than 60percent (cycle for cycle) compared to the Cortex and achieves this performance while also The answer is that the ARM CortexM4F has only a *single precision* (float) FPU, and not a double precision (double) FPU As such it only can do float operations in hardware but not for double type The solution in this case is to use float (and not double) constants Re Cortex M4F, FPU, and ThreadX Jump to solution I'll give FreeRTOS a shot, although I won't be changing underlying OS's for this current project, at this point

111 ARM Cortex M4 Sleep Modes Cortex M4 Power management methodology supports 2 sleep modes 1 Sleep 2 Deep Sleep From M4F processor logic point of view, there is little difference between the above two sleep modes However, it's the way these sleep modes may be utilized and/or implemented, which may make a difference For example, the Re Cortex M4F, FPU, and ThreadX Jump to solution I'll give FreeRTOS a shot, although I won't be changing underlying OS's for this current project, at this pointCodec2 for CortexM4F Contribute to piratfm/codec2_m4f development by creating an account on GitHub
