Abstract:
A data decompression module comprises:a data separation module operably coupled to receive compressed data and to separate components of the compressed data, wherein the components include motion vector data and run/level data; first memory interface operably coupled to the data separation module, wherein the components are provided to non-local memory via the memory interface; second memory interface operably coupled to receive the components from the non-local memory; packet processing module operably coupled to the second memory interface, wherein the packet processing module retrieves the components from the non-local memory at a rate independent of a rate in which the components were written into the non-local memory; data processing module operably coupled to the packet processing module, wherein the data processing module receives the retrieved components from the packet processing module and produces therefrom representations of uncompressed data; pipeline processing module operably coupled to receive the motion vector data and the representations of the uncompressed data and to produce therefrom the uncompressed data; and frame buffer operably coupled to store the uncompressed data.
