V Pot,
The C55x DSP might be a good fit for you. There are multiple filtering and DSP functions that are part of C55x DSPLIB which you can peruse.

Here's a quick training module to give you a glimpse on the C55x software…
Hi,
Yes, the TMS320C5545 DSP is well suited for voice processing.
In addition to Hossein's comments, the C5545 Booster Pack includes an on-board microphone and CODEC that supports the out of box demo that uses voice commands ("play", "pause", "stop…
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 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…
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…
SMART,
Please check out the C5x DSPLIB http://www.ti.com/tool/sprc100 . It has the fft routines/examples that would help.
Here is an app note detailing the DSP lib benchmarks which would also help.

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…
Hello Michael,
Check out the DSPLIB routines for vectors:
DSPLIB: http://www.ti.com/tool/sprc100
short maxidx (DATA *x, ushort ng, ushort ng_size) Index for maximum magnitude in a vector
short maxidx34 (DATA *x, ushort nx) Index of the maximum element…
Hi,
Have you reviewed the Chapter 2 - FFT Implementation on the TMS320C5535 DSP in the TRM ( SPRUH87 )?
It includes details about input and output data formats ( 2.5.1 Data Types & 2.5.2.2 HWAFFT Parameters ) and calling FFT functions from ROM ( 2.5.4 Function…
