摘要：
The present invention provides a method, apparatus and system for film grain cache splitting for film grain simulation. In one embodiment of the present invention a method for storing film grain patterns includes storing at least a first portion of film grain patterns in an internal memory and storing at least a second portion of the film grain patterns in an external memory. That is, in the present invention a method for film grain cache splitting for film grain simulation includes splitting the storage of film grain patterns between an internal cache and an external memory. In one embodiment of the present invention, the internal cache is integrated into an integrated circuit chip of a decoder.
