Abstract
A method for memory management in video decoding systems that avoids some of the costs and disadvantages with video decoding systems in the prior art. Some embodiments of the present invention are especially well-suited for use with the H.264 video decoding standard. The illustrative embodiment is a memory management technique that controls which data is in the fastest memory available to a processor performing video decoding. In particular, the technique seeks to ensure that the data the processor will need is in the primary memory and expunges data that the processor will not need. The technique is based upon an analysis of predictive video decoding standards, such as H.264. By employing this technique, the illustrative embodiment ensures the expedient decoding of video frames.
