  • Patent number: 8456197
    Abstract: A first sensing circuit has input terminals coupled to a true differential signal line and a complementary differential signal line. A second sensing circuit also has input terminals coupled to said true signal and said complementary signal. Each sensing circuit has a true signal sensing path and a complementary signal sensing path. The first sensing circuit has an imbalance that is biased towards the complementary signal sensing path, while the second sensing circuit has an imbalance that is biased towards the true signal sensing path. Outputs from the first and second sensing circuits are processed by a logic circuit producing an output signal that is indicative of whether there a sufficient differential signal for sensing has been developed between the true differential signal line and the complementary differential signal line.

  • Patent number: 8458556
    Abstract: In this invention, a new class of finite precision multilevel decoders for low-density parity-check (LDPC) codes is presented. These decoders are much lower in complexity compared to the standard belief propagation (BP) decoder. Messages utilized by these decoders are quantized to certain levels based on the number of bits allowed for representation in hardware. A message update function specifically defined as part of the invention, is used to determine the outgoing message at the variable node, and the simple min operation along with modulo 2 sum of signs is used at the check node. A general methodology is provided to obtain the multilevel decoders, which is based on reducing failures due to trapping sets and improving the guaranteed error-correction capability of a code. Hence these decoders improve the iterative decoding process on finite length graphs and have the potential to outperform the standard floating-point BP decoder in the error floor region.
