I would like to count the number of Instructions per Cycle executed on an ARM cortexM4 (or cortexM3) processor What it's needed is number of instructions (executed at runtime) of the code I want to profile and number of cycles that the code takes to execute 1 Number of Cycles Use the cycle counter is quite easy and straightforwardMar 29, 19 · 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 In C the 'f' suffix can be used to mark constants as floatFor example, the CortexM4F implements the DSP extension as well as the FPv4SP floating point extension In fact, I believe even NEON can be encoded in Thumb2
