Cordic Function in L series of STM32

[SRedd.5]

We started using the L series of the ST Micro for a project and found that it does not have CORDIC functions. What is the best way forward? Do we need to implement on our own? Or we have to migrate to G4 series.

Which STM32L ? L0 L1 L4 L5 ??

All have floating point libraries, some have an single precision FPU (32-bit floats), could also do table driven sin/cos estimations.

It is  STM32L431cb but i am using the Workbench Motor control software and it is G4 series and it has Cordic functions. I need to replace them with related functions and the return values and everything shall match else it may not run the motor properly. How to proceed?

>>How to proceed?

I supposed find someone who understands what the code / math is attempting to compute and code an alternative.

As far as I'm aware the CORDIC just speeds up some assort Transcendental Function math computation methods. The L4 has a CM4F core so should be able to do float math with some efficiency rather than needing fixed-point methods.

Talk to you local ST FAE or Engineering Support contacts related to your business with them.

Hello,

The CORDIC co-processor is exclusively available in the G4 series and offers hardware acceleration for mathematical functions, especially trigonometric ones.

This feature significantly enhances the speed of function calculation compared to software implementation.

However, if you wish to develop a project based on the L4 series, you can refer to the example project based on STM32L452RE available in MCSDK5.4.8 (Please refer to the attached workbench file).
