MCU-PLUS-SDK-AM243X: Which math lib is preffered in AM243x

Hi Logan,

The assigned expert is currently out of office. Please expect a delayed response. Thank you for your patience.

No problem, thank you.

Hello Logan,

Can you please confirm how did you get the RTS library ?

Did you integrate it from the other Microcontroller or SOC to AM243X ? Is this your planning ?...

Regards,

Anil.

Hi Anil, it's included in the AM24X MCU+SDK.

Hello Logan,

The FastRTS library is based on the lookup table method. So, the speed of operation is better as compared to MATHLIB.

And when we go with the Lookup table method, the MSRAM/DDR memory is consumed more as compared to MATHLIB libraries .

Did you check the benchmarking of the two libraries in the release build and see no difference in the performance ?

Regards,

Anil.

where can I see the benchmark? I read the application note of Mathlib and the result of FastRTS library is not motioned there.

Hello Logan,

I looked at the benchmark results from the link below  and it seems that in both modes the results are the same.

Can you please run the FastRTS example in the release build and see these results compared with the MATHLIB results?

I feel that, based on the link below, the MATHLIB and FastRTS libraries benchmark results are the same.

Regards,

Anil.

github.com/.../mathlib_benchmark.c

Thank you Pratheesh and Anil. I will run the benchmark test to see if I can get same result.

I noticed there is fourth math lib for sin and cos. TMU_trig.

Hello Logan,

In the MCU+SDK, we only compile ti_arm_trig.c files.

I feel that we have not compiled the RTS library.

So, add the RTS files to the make file below and compile them.

Later, use RTS API's from the Application. 

Please use these two libraries only .

Regards,

Anil.
