  • Data caching method and apparatus for video decoder
    Patent number: 10542276
    Abstract: A data caching method for a video decoder includes: receiving a data request from the video decoder, wherein the data request is for requesting one or more reference pixel blocks to decode a present pixel block, and the data request contains one or more reference motion vectors each corresponding to a reference pixel block; determining, for each reference motion vector in the data request, whether the reference pixel block corresponding to the reference motion vector has been cached in a cache memory which caches a plurality of reference pixel blocks; and if the reference pixel block corresponding to the reference motion vector has not been cached in the cache memory: A) determining an expected usage number and a historical usage condition for each reference pixel block which has been cached in the cache memory, wherein the expected usage number indicates how many times the cached reference pixel block will be used in decoding of a predetermined number of subsequent pixel blocks after the present pixel block,
