Abstract
The present invention is directed to data communication systems and methods thereof. According to various embodiments, the present invention provides a communication with a reconfigurable forward-error-correction (FEC) module. The FEC module processes data received from two or more communication lanes, and depending on the mode of operation, the FEC module can combine data from the two or more communication lanes and perform error correction on the combined data, or the FEC module can processes data from the two communications lanes separately and perform error correction independently for the each of the data communication lanes. There are other embodiments as well.
Claims9
A system comprising:
- a receiver configured to receive one or more codewords and to determine a data rate of the one or more codewords;
- and
- a processor including at least two codeword processing circuits, the processor being configured to select, in response to the determined data rate, whether i) to connect two or more codeword processing circuits to process together in parallel one of the codewords using the two or more of the codeword processing circuits that are connected together in parallel, or ii) to process two or more of the codewords using two or more of the codeword processing circuits that are unconnected to each other, each of the unconnected codeword processing circuits processing a different codeword among the two or more of the codewords.
