METHOD AND SYSTEM FOR DECODING 8-BIT/10-BIT DATA USING LIMITED WIDTH DECODERS

摘要

A method and system for decoding 8B/10B data is provided. In one embodiment, the method includes the steps of determining the presence of one of a plurality of predetermined data sequences within a first portion of a data word, translating the predetermined data sequences into representative signals (flags) having a smaller aggregate data width than the first portion of the data word, and providing the representative signals together with remaining portions of the data word to a logic block for decoding. This embodiment of the present method allows the encoded data to be decoded using limited-width decoders, allows first and second portions of each encoded data word to be decoded concurrently, and allows the decoding of the encoded data words to be pipelined to increase the throughput of the decoder.
