The Viterbi decoding unit is arranged to process the input signal and generate the Viterbi-processed data. In addition, the control circuit is arranged to control at least one component of the apparatus based upon at least one signal within the apparatus. Additionally, the component includes a phase locked loop (PLL) processing unit, an equalizer, and/or the Viterbi decoding unit. An associated apparatus including an equalizer and a Viterbi module is further provided. An associated apparatus including a Viterbi decoding unit and a control circuit is also provided. An associated apparatus including an equalizer, at least one offset/gain controller, and a Viterbi module is further provided. An associated apparatus including an equalizer, a Viterbi module, and a peak/bottom/central (PK/BM/DC) detector is also provided. | 04-21-2011 |
20110163758 | Efuse Macro - An eFuse with at least one fuse unit is provided. The fuse unit includes a common node, a sensing unit with a first input terminal and a second input terminal, at least one fuse coupled between the common node and the first input terminal of the sensing unit with a resistance, and a switching unit coupled between the common node and the second input terminal of the sensing unit. A resistance of the switching unit is equivalent to a first resistance in a normal mode and equivalent to a second resistance in a test mode, and the second resistance is higher than the first resistance. The sensing unit generates an output signal indicating whether the fuse is blown or not according to the resistances of the fuse and the switching unit. | 07-07-2011 |
