1. A device of comma detection and word alignment for n-to-m bit conversion in serial transmission, the device comprising:

  • a two-stage pipeline architecture, which receives a serial data stream;

    a comma detection logical circuit, which detects the distribution of a k-bit comma pattern when the serial data streams enter the first-stage pipeline in the pipeline architecture; and

    a word alignment logical circuit, which extracts an n-bit word data when the serial data streams enter the second-stage pipeline in the pipeline architecture;

    wherein the locations of the n-bit word data are selected according to the locations of the k-bit comma pattern, and the output data go through an n-to-m bit conversion to obtain a m-bit data.
