Abstract
A method and system are disclosed for managing cache memory in a dual-pipelined CABAC encoder. A request for a context model is received from both encoder pipelines. If the requested context model is not stored in cache, the requested context model is retrieved from a context table. At least one context model stored in cache is written to the context table. The retrieved context model is updated and written to the cache. If the requested context model is stored in cache, and if the requested context model was updated in the previous clock cycle, the requested context model is retrieved from the pipeline, updated, and written to cache. If the requested context model is not stored in cache, and if the requested contest model was not updated in the previous clock cycle, the requested context model retrieved from cache, updated, and written back to cache.
