Elias Konikas' Project

Primary LanguageC

A template project for audio processing applications using the C5515 eZDSP kit.
This project uses the small memory model in order to support hardware-accelerated 
FFTS. The system is set up using register programming. In each step appropriate
references to relevant documentation are given as comments. Generally, the project
has not been extensively test and has possibly significant bugs. It is provided to
the community so a more robust and useful template can be developed with input from
those interest. Also note, that in no case is the code optimal in terms of memory
and/or performance.

If you have any comments, suggestions, etc, contact me.

Parts of the project are based on:
- The system initialization function is based on the C5515 audio filter example.
  (http://code.google.com/p/c5505-ezdsp/)
  
- The SAR and switch functionality provided by Spectrum Digital's example code.

- The AIC3204 initialization by Sean O' Brien.

Notes:
- Two wrapper functions have been created to allow simple FFT/IFFT implementation
  and conversion between complex (32-bit packed) and real numbers (16-bit).

- You have to compile the following project: 
  C:\Program Files\Texas Instruments\ccsv4\emulation\boards\usbstk5515_v1\lib
  using small memory model and 16 bit pointer math.
  
- In order to support higher sampling rates you have to turn on optimizations.
