The 80 MHz core with FPU handles single-precision floating-point arithmetic in hardware, so sensor fusion, PID loops, and FFT-based condition monitoring run without a software emulation penalty. Against a Cortex-M3 at the same clock, this part cuts the cycle count for a multiply-accumulate from several instructions to one.
