<p>A method and apparatus for motion compensation using a cache memory coupled to the motion compensation circuitry. The motion compensation method takes advantage of the fact that significant spatial overlap typically exists between a plurality of blocks that make up a macroblock in a motion estimation algorithm. Accordingly, a region of pixels may be stored in the cache memory and the cache memory may be repeatedly accessed to perform interpolation techniques on spatially adjacent blocks of data without having to access main memory, the latter being extremely inefficient and wasteful of memory bandwidth.</p> |
