<P>PROBLEM TO BE SOLVED: To provide a communication protocol and serial interface having an approximately fixed barrier clock and capable of adapting to a variety of communication rates. <P>SOLUTION: The interface employs a variable-length frame that may be expanded or reduced to obtain a desired communication rate, even though a barrier clock rate is kept approximately constant. A method for designing an agile barrier interface is also provided. In particular, the barrier clock rate is preferably selected to be an approximately common multiple of the various communication rates that the barrier interface must handle. A frame length corresponding to each communication rate is obtained by dividing the barrier clock rate by ΣΔ rate. Thus, there is provided an agile communication circuit capable of communicating data through a serial interface at a variety of data rates and at an approximately fixed interface clock rate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
