摘要： A decision-feedback equalizer (DFE) can be operated at higher frequencies when parallelization and pre-computation techniques are employed. Disclosed herein is a DFE design suitable for equalizing receive signals with bit rates above 10 GHz, making it feasible to employ decision feedback equalization in silicon-based optical transceiver modules. One illustrative embodiment includes a front end filter to reduce leading intersymbol interference in a receive signal; a serial-to-parallel converter and at least one pre-compensation unit that together convert the filtered signal into grouped sets of tentative decisions, the sets in each group being made available in parallel; a set of pipelined DFE multiplexer units to select a contingent symbol decision from each set of tentative decisions to form groups of contingent symbol decisions based on a presumed sequence of preceding symbol decisions; and an output multiplexer that chooses, based on preceding symbol decisions, one of said groups of contingent symbol decisions.

摘要： In a method for causing data to be written to a non-volatile medium, first data to be encoded and written in a sector of the non-volatile medium as a codeword is transmitted to a write or read/write channel device, and a write gate signal corresponding to the sector is asserted. Asserting the write gate signal indicates to the write or read/write channel device when to write the codeword to the sector. While asserting the write gate signal to cause the codeword to be written, second data to be encoded and written to the non-volatile medium is transmitted to the write or read/write channel device.

摘要： In a method for causing data to be written to a non-volatile medium, an indication of a size of a sector or a sector fragment may be transmitted to a channel device, and an indication of a size of a codeword to be written in the sector may be transmitted to the channel device. Data to be iteratively encoded and written in the sector as the codeword may be transmitted to the channel device. A write gate signal corresponding to the sector or the sector fragment may be transmitted to the channel device to indicate to the channel device when to write to the sector or the sector fragment.
