Abstract
A method and apparatus for video decoding of compressed video data begins by generating a plurality of coefficients based on run level data of two-dimensional frequency components corresponding to the compressed video data. As the coefficients are generated, they are stored in a coefficient section of memory. Once the coefficients have been stored, they are utilized to generate intermediate results. As the intermediate results are being generated, they are stored in an intermediate section of the memory. Next, representations of the video data are generated based on the intermediate results and stored in an output section of the memory. The storing and retrieving of the coefficients, intermediate results, and representations of the video data are done in a time multiplexed manner.
