Digital Filter (FIR and IIR) Libraries

Category: Software
Software Version: Not Applicable

Got the AudioFilter_Callback_BF706Mini example of the EZKIT-BF706Mini working under debug and as a flashed program on the eval kit.

This example uses IIR filters. I would like to use FIR filters to do some audio processing.

Questions:

1. Where can I find FIR/IIR/DSP libraries/APIs for use with the eval kit ?

2. Are there examples out there of FIR/IIR filters for the eval kit which would allow simple substitution of coefficient values into the code ?

Any help appreciated.

  • Hi,

    You can get more information about Library APIs from the below help path.
    CrossCore® Embedded Studio 2.12.0 > Blackfin® Development Tools Documentation > C/C++ Compiler and Library Manual for Blackfin® Processors > DSP Run-Time Library > DSP Run-Time Library Reference > fir

    We are checking in our database like whether we have any sample code for FIR. We will update to you.

  • Hi,

    We hope you have created a sample project for the FIR filter by referring to the detailed information provided in the Library APIs help path.

    For more information of the FIR filter, please refer to the attached ASM path:

    Blackfin/lib/src/libdsp/fir_fr32.asm

    Hope this helps.
