TMS320F28377S: Constant Q Transform

db_woodall

Part Number: TMS320F28377S
Other Parts Discussed in Thread: CONTROLSUITE

I searched through ControlSuite, particularly the floating point library, and didn't see an implementation of the Constant Q Transform. This transform is similar to the FFT, but the output frequency bins are logarithmic instead of fixed by the FFT size. Anyone know of an existing port? This would be a welcome addition to CS.

Thanks, dave

Hello,
I am writing to let you know that a C2000 team member has been assigned to this post and should be answering shortly.

No we do not have an implementation for this. I'll file this as a customer request.

Thanks Manish,

The reason I ask is that many implementations I've seen online are not optimized for pipelined DSPs such as the C2000's. Having a tested, optimized transform would encourage use of C2000 devices for auditory sciences and musical applications.
I will close the ticket, but yes, please add this to the list of customer requests!

thanks, dave
