Abstract: The paper designed a multichannel buffered serial port(McBSP). In order to accomplish the achievement of time division of multiplexing(TDM), the design added multichannel controlling logic basis of standard serial port. Additionally, compressing and expanding hardware allows compressing and expansion of data in either u-law or a-law format. The serial port has good performance according to the synthesis result and can be widely used in the digital signal processing(DSP)systems.

Key words: multichannel, serial port, a-law, u-law
