摘要： Domain-based cache management methods and systems, including domain event based priority demotion (“EPD”). In EPD, priorities of cached data blocks are demoted upon one or more domain events, such as upon encoding of one or more macroblocks of a video frame. New data blocks may be written over lowest priority cached data blocks. New data blocks may initially be assigned a highest priority. Alternatively, or additionally, one or more new data blocks may initially be assigned one of a plurality of higher priorities based on domain-based information, such as a relative position of a requested data block within a video frame, and/or a relative direction associated with a requested data block. Domain-based cache management may be implemented with one or more other cache management techniques, such as least recently used techniques. Domain-based cache management may be implemented in associative caches, including set associative caches and fully associative caches, and may be implemented with indirect indexing.

摘要： A memory system includes a plurality of memory device ranks. A memory controller having a connection with the plurality of memory device ranks is adapted to obtain command information being issued to one of the plurality of memory device ranks. The memory controller is also adapted to generate a power weight value based on a command type from the command information. The memory controller increments a power count of the one of the plurality of memory device ranks by the power weight value generated. The memory controller then compares the power count of the one of the plurality of memory device ranks to a threshold value set for the one of the plurality of memory device ranks. If it is determined that the power count exceeds the threshold value, the memory controller is adapted to throttle the one of the plurality of memory device ranks.
