Hi,
Thanks for your post.
In my opinion, C6748 processor would be the right choice for low power and low cost solutions for audio based applications. There is a C6748/OMAPL138 LCDK development tool which is easy-to-use, affordable and scalable.
L138/C6748 development kit is part of single core DSP kit includes either a TMS320C6748 DSP or an OMAPL138 application processor with 456 MHz C674x Fixed/Floating point core. It has On-chip RTC, DDR2 running at 150 MHz, NAND FLASH and SD/MMC Slot, USB Serial Port, Fast Ethernet Port, B Host port (USB 1.1), USB OTG port (USB 2.0), SATA Port , VGA port, LCD Port (Beagleboard XM connectors), three AUDIO Ports, Composite IN (RCA Jack) and Leopard Imaging Camera Sensor Input.
For more details on C6748/OMAPL138 LCDK, please refer the below wiki:

Thanks & regards,

Hi,
Thanks for your update.
If this is the case, please download the TI C67x DSPLIB from the below link in which you could see filtering and convolution libaray functions:
http://www.ti.com/tool/sprc121
For C674x device, please check the supported kernel functions for C674x DSP_LIB from the below wiki:
http://processors.wiki.ti.com/index.php/C674x_DSPLIB#DSPF_sp_fir_gen_.28FIR_Filter.29
Also, please refer the c67x DSP FIR/IIR signal processing examples from the application report as given below:
http://www.ti.com/lit/an/spra947a/spra947a.pdf
Kindly check the c67x DSP library programmer's guide for filtering and convolution functions as below:
http://www.ti.com/lit/ug/spru657c/spru657c.pdf
The sample example code with the project from DSPF_sp_fir_gen can be found in the DSPLIB package under the path ~\ti\dsplib_c674x_3_2_0_1\packages\ti\dsplib\src\DSPF_sp_fir_gen. Please give it a try to see the sample implementation and check to see , how the API's are used for the same.
Thanks & regards,
