1. A method of detecting a bit pattern in a data stream, said bit pattern defined by a group of N bits, the method comprising: storing, during a load mode, a first binary value at a first address of a memory, said address defined by the group of N bits; storing, during the load mode, a second binary value at remaining addresses of the memory; providing a plurality of periods including a systolic cycle; retrieving, during each period, the stored binary value from an address of the memory defined by a different one of N-bits of the data stream; and detecting the bit pattern using a detector cell if the binary value retrieved in response to an associated one of the N-bits of the data stream is the first binary value.
