Luis,
Please see e2e.ti.com/.../309799
Also, have you checked out the DSPLIB package for C55x? there are a bunch of various filters in the package. http://www.ti.com/tool/sprc100

Hi Minjeong,
c5000 DSPs are suitable for audio processing but I'm not sure in details what processing you will do. As I understand you will connect a microphone to record the sounds and then will make processing. Therefor I recommend you the following…
Daniel,
I would suggest taking a look at the DSPlib for C5000. This package has a plethora of information as it pertains to various DSP routines and the C55x core. You should be able to find alot of details on filter design in the documentation along…
Hi Kanchan,
Why don't you try the DSPLIB FFT routines instead of using the hardware accelerator.
They will still be fixed point, but offer 32-bit FFT, which might give you enough precision
If these FFT routines provide you with a working proof of…
Hi Hao, The C5545 is capable of 16-bit fixed-point FFT conversions, up to 1024-pt in the hardware accelerator (HWAFFT). DSPLIB provides optimized FFT C-callable assembly for FFT lengths up to 1024-points also. It is described in the Chapter 2 of the C5545…
FS2131,
I would say its certainly feasible, but you would need to get a C5515 EVM and start to evaluate its capabilities in order to ensure it fits your needs. Please see the C55x DSPLIB http://www.ti.com/tool/sprc100 . There are various examples for…
Hi,
The C55xx FFT hardware accelerator only supports 16-bit fixed point.
Floating point is not native on C55x but can be computed in software (relatively expensive).
FFTs can also be computed in software using code from DSPLIB: http://www.ti.com…
I don't have a problem with CSL Library, I mean this libraries : http://www.ti.com/tool/sprc100
I'm using CCS4 supplied with TMS320C5502 eZdsp Evaluation Board. I tried both with imported example and with blank project created by me. Attached CSL Libraries…
This doesn't look right - read through the fir2 section of the TMS320C55x DSP Library Programmers Reference
http://www.ti.com/lit/ug/spru422j/spru422j.pdf
And look at the fir2 examples at <DSPLIB install path>\dsplib_2.40.00\EXAMPLES\fir2\
Why is…
