Hardware floating-point operation of s32K144

[zhangchun]

hello

1、The system frequency is 80MHZ, icache is enabled, and FP instructions (hard) are configured. The execution time during this period needs to be 15us, is it reasonable? It feels like hardware floating-point operations are not actually being used

2、Is it reasonable that the execution time of the above code is not stable at 15us, and some times it may become 10us or 25us?

Thanks
