I have tesed runtime of MLIB_Mul_FLT and float*float(e.g. 1.2f*1.3f), and once MLIB_Mul_FLT spends about 0.22us, but when I directly use 1.2f*1.3f, it only spends about 0.1us.
Since MLIB_Mul_FLT is a inlined function, shouldn't these two methods be the same?
Why does it happen?
By the way, is the runtime of floating point multiplication normal（0.1us once）？Or should I turn on MPC5744P's FPU first by some code?
