  • Data communication method
    Patent number: 7079528
    Abstract: In a method of communicating a plurality of parallel data packets from a first data parallel bus to a second parallel data bus, each of the plurality of parallel data packets is separated into a first portion and a second portion. Each first portion is converted into a first serial data stream and each second portion is converted into a second serial data stream. The first serial data stream is transmitted over a first serial data channel and the second serial data stream is transmitted over a second serial data channel. The first serial data stream is converted into a plurality of first received portions and the second serial data stream is converted into a plurality of second received portions. Selected first received portions are combined with corresponding selected second received portions so as to regenerate the plurality of parallel data packets.

  • Modification of bus protocol packet for serial data synchronization
    Patent number: 7065101
    Abstract: An apparatus for enabling transmission of parallel data from a first parallel bus to a second parallel bus via a serial data channel includes a first logic element that generates a synchronization character used in a serial data transmission protocol upon detection of a parallel synchronization packet. A serializer converts data from the first logic element into a serial data stream. A de-serializer converts the serial data stream into a plurality of parallel data packets. A second logic element detects the synchronization character and converts the synchronization character into a parallel synchronization packet.
