Hardware floating-point operations

zhangchun — Tue, 20 Jun 2023 11:56:45 GMT

Hello

I am using S32DS to build a motor Control engineering based on s32K144. This project involves a lot of floating point operations. How can I configure S32DS to support floating point operations

Thank's!

@Robin_Shen

Thank you for your reply

After using hardware floating-point operations, the time consumption of a portion of the code that heavily utilizes floating-point operations has changed from 105us to 73us. Is this reasonable?
