摘要: Disclosed is a method and circuit for synchronizing dual data buses. In one embodiment, the method includes a receiving circuit receiving first and second streams of multibit data portions transmitted via first and second parallel data buses, respectively, coupled thereto. The receiving circuit compares first-stream multibit data portions with a first predefined multibit data portion to identify a first-stream multibit data portion that matches the first predefined multibit data portion. The receiving circuit stores into a first FIFO, all first-stream multibit data portions that follow the identified first-stream multibit data portion. The receiving circuit also compares second-stream multibit data portions with a second predefined multibit data portion to identify a second-stream multibit data portion that matches the second predefined multibit data portion. The receiving circuit stores into a second FIFO, all second-stream multibit data portions that follow the identified second-stream multibit data portion.

摘要: Disclosed is a method and apparatus for adapting bandwidth utilization over fabric links. In one embodiment of the method, a transmitting device transmits data at a first non-zero rate to a memory for storage therein during a first period of time. The transmitting device then transmits data at a second non-zero rate to the memory for storage therein during a second period of time. The second period of time is subsequent to the first period of time, and the second non-zero rate is greater than or less than the first non-zero rate. This method may find application in switching network where the transmitting device is contained in a switching fabric, the memory is a FIFO buffer contained in a line card coupled to the switching fabric via a data link, and where the transmitter transmits data via the data link to the FIFO buffer for storage therein.
