ADI 公司的DSP ADSP21369 EZ-KIT LITE开发板的全部源代码

-------------------------------------------------------------------------------
Example:  C Block-based SPDIF TalkThrough
Target:   ADSP-21369
Date:     July 29, 2005
Tools:    VisualDSP++ 4.0
Hardware: ADSP-21369 EZ-KIT LITE
-------------------------------------------------------------------------------
This project contains a talkthrough example using the onchip SPDIF receiver to
acquire and output an audio stream. The digital audio data is available for
processing in the file SPORTisr.c. The block size is 384 samples to match the
block size for the SPDIF stream.

The SPDIF receiver derives the MCLK, BCLK, and LRCLK from the data stream and
passes these to the SPDIF receiver.
-------------------------------------------------------------------------------
Instructions: Apply an input signal to P8 on the ADSP-21369 EZ-KIT LITE, and
              attach an output device to the selected channel of P9.
