    摘要: Provided is a method and system for performing color look-up table (CLUT) and gamma correction for video pixel data. A system includes a memory configured for storing CLUT parameters and gamma correction parameters therein. Also included is an input matrix coupled to the memory and configured to receive first and second type pixel data. The memory receives the first type pixel as an address to the stored CLUT parameters and receives the second type pixel data as an address to the stored gamma correction parameters.

    摘要: Methods and systems for processing video data utilizing fast RUN-LEVEL encoding are disclosed herein and may comprise detecting sequential video data within a leading portion of decoded video data entries. If the detected sequential video data comprises one or more zero video data entries, a RUN coefficient may be generated utilizing the zero video data entries. In this regard, a RUN coefficient may indicate the number of zero video data entries in the detected sequential video data. If the detected sequential video data comprises one or more non-zero video data entries, a LEVEL coefficient may be generated utilizing the non-zero video data entries. The generating of the RUN and LEVEL coefficients may be executed in a single cycle, thereby increasing the processing speed of RUN-LEVEL encoding.
