Abstract
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.
