  • Multi-channel buffered serial port debugging
    Patent number: 7028118
    Abstract: In digital signal processors serial data is passed in out and of the chip in a time division multiplexed (TDM) fashion. The TDM stream consists of many independent channels of serial data. The complexity of generating interleaved TDM serial data from multiple sources particularly in the case of multi-processor systems. This process is normally driven by a program resident on each processor. The proper sequencing of the TDM serial stream must be tested prior to making the multi-processor device ready for its application. This invention describes the use of minimal added hardware and a single output pin allowing the test and debug of program errors or device malfunctions in output serial data.
