Audio Processing using BF537

Hi all,

   I am new to DSP,just started learning one month back.

I have been given the task of audio processing in BF537 .

1) Audio filter design(DNR-dynamic noise reduction)

2)VOX implementation

3)cahnnel filters of 12.5khz and 2 KHz....

4)Scrambler and Descrambler.

i am not understanding from where to start.

Please someone help me out, i need guidence.

I have deadline on july last week.

  • Hello,

    with tool chain I just mean the hard/software that you are using and how it works. But I think we can skip these basics by now.

    I have attached you a UART example code. This is for connecting a PC terminal program to the EZ-KIT and do some UART loopback. See EE-347: http://www.analog.com/static/imported-files/application_notes/EE-347_rev.1pdf.pdf

    You will find the functions you need in ADSP-BF534-UART.c / ADSP-BF534-UART.h

    The ISRs use macros (e.g. ERROR(1,"...") ) instead of a standard printf functions, just to let you know...

    One additional hint as you have created your own definitions:

    \Blackfin\include\defBF537.h

    \Blackfin\include\defBF534.h

    contain these register mask definitions already. Usually you just need to include blackfin.h.

    Regards
