  • Patent number: 9436244
    Abstract: Methods and apparatus related to adaptive control loop protection for fast and robust recovery from low-power states in high speed serial I/O applications are described. In some embodiments, a first bit pattern is detected, at a first agent, that indicates a speculative entry by a second agent into a low power consumption state and one or more control loops are frozen. A second bit pattern is detected (after entering the low power consumption state) that indicates exit from the low power consumption state by the second agent and the one or more control loops are unfrozen (e.g., in a specific order). Other embodiments are also claimed and/or disclosed.

  • Patent number: 9258568
    Abstract: A method and apparatus is provided for implementing quantization in encoding/decoding. Firstly, the quantization on the picture transformed coefficient matrix is performed using a quantization parameter model, that is, the coefficient matrix is modeled as a parameter model represented by only several parameters, in which the parameter model includes two sorts of parameters, frequency band distribution parameters and frequency band weighting parameters. Thus, a quantization matrix conforming to the human vision system can be obtained by controlling the model parameters and the subjective quality of the encoded picture can be easily controlled. Secondly, the method does not need to store or transfer the quantization matrix in the bitstream which help to improve the encoding efficiency. Finally, the quantization on picture transformed coefficients using the method is well adapted to the content information of the picture to be encoded.
