Abstract
A digital transmission framing system utilizing an address array containing pointers to a framing pattern reference register. The address array contains an entry for each set of possible framing bits. Pointer values reference the last bit of a consecutive-bit sub-pattern of the reference register that the previously received bits in this frame bit position have matched. As data bits are received, the associated pointer value is incremented by one to point to the next bit of the reference register, and the received data bit is compared to the newly referenced reference register bit. If the received data bit matches the newly referenced reference register bit, the associated pointer is updated with the incremented value and the corresponding frame bit position of the received data bit remains a candidate for the actual framing bit position. This matching operation continues until only one eligible framing bit position is identified in the input data frame. Bit 0 of the framing bit pattern in the transmission stream is then identified and a synchronization signal is generated.
