To know time taken to calculate CRC

[Jusaira]

Hi Team,

I would like to know how much time it takes to calculate CRC for a 1KB data by S32K146 with BUS clock frequency 40 MHz(Core clock = 80 MHz). From the reference manual I got the information for 1 Byte it takes 2 clock cycles. Can you please provide some information or results on this.

Hi Jusaira,

Maybe you can measure it by refer to: Measure the running time of one function on S32K
The unit of measurements of the variabile ARM_CM_DWT_CYCCNT is CORE_CLK cycles.

Best Regards,
Robin
