SPT Kernel Programming for S32R274

[User133]

Aside from the given kernels, I want to program my own kernel for convolution on S32R274.

How can I program my own kernels? I read the SPT Kernel files in PSPT, and I want to learn how to program them myself.

I would greatly appreciate any assistance on this matter.

Thank you in advance.

Hello,

the SPT kernels are a good starting point, in conjunction with the S32R274 Reference Manual chapter 45 (SPT ) should be enough to start with

depending on what type of convolution, it may be tricky to implement on SPT, but the question is more generic

if it's a convolution with fixed parameters, the FIR block can be used,

if there's a convolution between 2 signals, that may be problematic for SPT

convolution can be done with FFT and point to point multiplication

it highly depends on the exact operations that the user wants to do, there is no one answer to fit all possibilities here

Best regards,

Peter
