Abstract: System and method of frame alignment at a receiver with power optimization mechanisms. A framer uses one or more comparators to search for the FAW in the incoming data, with each comparator configured to serially compare multiple windows of a parallel M-bit block (as provided from a parallel data bus) with the FAW. Multiple comparators in the framer may operate in parallel to search for the FAW at different windows. This configuration can significantly reduce the comparator count and so the gate count as well as the chip area in a framer. Power consumption can be advantageously reduced as one comparator operating serially consumes less power than multiple comparators in parallel because less gate toggling is involved.
