| Abstract: | The TLC320AD50C principles and main characteristic of the serial port of TMS320VC5402 are introduced and the configuration of control registers and their process of operation are analyzed. A simple and practical interface between DSP and TLC320AD50C is designed from both hardware and software. In this design, the TLC320AD50C is directly connected to the serial port McBSP, not occupying DSP'S parallel data bus and avoiding from bus interference. The method derived in this paper has been successfully applied in processing systems of speech. |
