Abstract: A buffer device is used by a compressor/decompressor with block prediction for storing information needed to encode/decode a pixel line. Vector information (e.g., final block prediction vector information and/or partial block prediction vector information) of at least one later pixel group is computed while a current pixel group is being encoded/decoded. The buffer device does not need to store vector information of all pixel groups of one pixel line at the same time. For example, one pixel line is composed of M pixel groups; and when the compressor/decompressor is encoding/decoding the current pixel line, final/partial vector information sets of at most K pixel groups are allowed to be stored in the buffer device simultaneously, where K is a positive integer smaller than M.

Abstract: A data processing apparatus includes a storage element and a clock controller. The storage element has storage partitions, including a first storage partition and a second storage partition. The clock controller controls clock driving of the first storage partition and the second storage partition. When a processing circuit is configured to operate in a first condition to process a first data sample with a first bit width, the clock controller enables clock driving of both of the first storage partition and the second storage partition. When the processing circuit is configured to operate in a second condition to process a second data sample with a second bit width, the clock controller enables clock driving of the first storage partition and disables clock driving of the second storage partition.

Abstract: A method and apparatus for a multiple-channel image/video coding system are disclosed. A residue generation process is applied to the image/video data to generate residue data. A set of integer operations is applied to the residue data across the input channels to generate residue transformed data having multiple output channels. In one embodiment, the residue transformed data associated with a first output channel is related to the difference between a first residue data associated with a first input channel and a second residue data associated with a second input channel. In another embodiment, the residue transformed data associated with a second output channel is related to the second difference between a threshold and a third residue data associated with a third input channel, and wherein the threshold corresponds to the first truncated or rounded average of the first residue data and the second residue data.
