摘要： An intra prediction method for a luma block of a video is provided. The present invention provides a solution for unifying the intra prediction of the luma block of the video, which simplifies a plurality of prediction equations defined by video standard. The predication values of common terms in the prediction equations are calculated in advance and directly selected for predicting the luma block of the video. Accordingly, only a few function parameters or register settings are needed to be modified, and then a plurality of prediction modes may use the same software function or hardware circuit to obtain the prediction values.

摘要： According to some embodiments, bin data may be input and, based on a portion of the bin data, an entry in a search table may be determined. An indication of whether the search is complete may then be read from the search table along with at least one of: (i) a base symbol value or (ii) information about a next node. If the search is not complete, the process may continue to determine entries in the search table based on the information about the next node and additional portions of the bin data. When the search is complete, a decoded symbol may be calculated based on the last base symbol value and a remaining portion of the bin data associated with an extra bin length read from the search table.

摘要： Encoding or decoding digital video frames in intra-prediction mode by selecting column reference data locations for blocks adjacent a current block from a column reference data buffer storing column reference data samples for no more than two macro blocks of the frame. In some cases, the column reference data buffer may include a storage size for samples of a first column of data of blocks of one macro block of luminance samples. Encoding and decoding may also include selecting row reference data locations for blocks adjacent a current block from a row reference data buffer storing row reference data samples for at least one row of macro blocks of the frame. In some cases, the row reference data buffer may include storage for samples of a first row of data of fourteen successive blocks spanning two rows. The concept can be applied to various video processing components and standards.

摘要： Arbitrary patterns of address locations of digital data can be efficiently read from a memory of a signal processor. For example, a first memory address generator receives a first memory command signal from a first communication register to retrieve a first set of data from memory according to a look up table of memory addresses. The first memory access generator reads the look up table of memory addresses, which contain a second set of memory commands and reroutes the second set of commands to a bypass register. In turn, the second set of memory commands stored at the bypass register are read by a second memory address generator which retrieves a second set of data from memory according to the second set of memory command signals read out of memory by the first memory address generator.
