S32K Chip Performance and Motor Control

zhangchun — Wed, 30 Aug 2023 12:38:48 GMT

hello

I am currently using s32k144 to create a motor controller, but due to the performance impact of s32k144, the motor controller cannot achieve the expected state.

At present, I have used a system frequency of 80M in my code, with O3 as the optimization level, cache enabled, FPU enabled, and fixed-point operations used to improve code execution efficiency.

I want to replace a chip without changing the current code to improve performance, and choose a chip with a higher system frequency and larger cache, among other factors.

excuse me

1. Are there any other optimization plans to improve code performance

2. Do the s32k series chips have the same IP addresses as S32K144's FTM, TRGMUX, PDB, ADC, and have higher performance?

Thanks!

Hi,

did you tried to use AMMClib? This library is very well optimized for motor control.
