C28X FPU Libraries

Alexey Tsirlin

Hi.

I am looking for complex to complex FFT implementation for dolfino DSP using FPU. I know that I can use real to complex FFT twice to get the desired result, but I guess having complex to complex FFT will give much higher performance. Are there any other FPU libraries available from TI (or may be will available soon)? Or it is better to start writing it by my own?

Thanks.

Alexey,

I think you're using this library C28x Floating-Point Unit Library

There is also a Fast RTS library that could help you build your own function. http://focus.ti.com/docs/toolsw/folders/print/sprc664.html

Yes, I am using this beta library. The question is if it worth trying write my own function or just executing the provided FFT function twice? Will I have some perfomance boost in writing my own function?

Thanks, Alexey.

Alexey,

Click on my profile and then under my avatar select "start a conversation". I will send you some very prelimary complex FFT code for 28x+FPU.

I am also looking for a complex FFT for Delfino. I'm curious to know what you used in the end?
