Fine-grain pipelined adaptive decision-feedback equalizer (ADFE) architectures are developed using the relaxed look-ahead technique. this technique, which is an approximation to the conventional look-ahead computation, maintains functionality of the algorithm rather than the input-output behavior. thus, it results in substantial hardware savings as compared to either parallelprocessing or look-ahead techniques. the delay relaxation, delay transfer relaxation, and sum relaxation are introduced for purposes of pipelining. Boththe conventional and the predictor form of ADFE have been pipelined. the performance of the pipelined algorithms for the equalization of a magnetic recording channel is studied. It is demonstrated via simulations that, for a byte error rate of 10-7 or less, speed-ups of up to 8 can be easily achieved withthe conventional ADFE. the predictor form of ADFE allows much higher speed-ups (up to 32) for less than 1 dB of SNR degradation.
Lee's (1961) maze-routing algorithm has been a popular method for routing wires in VLSI circuits. It can also be applied to a variety of other problems, such as robot path planning. Although the algorithm is simpl...
