摘要

Power constraints constitute a critical design issue for the portable video codec system, in which the external dynamic random access memory (DRAM) accounts for more than half of the overall system power requirements. With the ultrahigh-definition video specifications, the power consumed by accessing reference frames in the external DRAM has become the bottleneck for the portable video encoding sy...
