simple benchmark test I have used to compare the performances of F303RE (M4+FPU) vs KL25Z (M0+) : integer/float/double operations and AnalogIn. Apparently the M4+FPU is not really faster for DP operations. On F303RE "AnalogIn" is by many times slower compared to the max ADC speed of the STM32F303 MCU (5 Msps)
