Power has become the overriding concern for most modern electronic applications today. To reduce clock power, sequential clock gating is increasingly getting used over and above combinational clock gating. Given the complexity of manually identifying sequential clock gating changes, automatic tools are becoming popular. However, since these tools always(More)
With advances in video coding standards like H.264 and HEVC coupled with those in the display technology, Ultra HD contents have started taking the mainstream. This is driving the need for high computation and memory bandwidth in current multi-media SOCs. In this paper, we present a monolithic multi-format video codec engine which achieves Ultra HD(More)
Power has become a first-class design constraint for ASIC/SOC designers. Reducing both dynamic and leakage power is imperative to meet power budgets for portable devices as well as to ensure that the systems that these ASICs are part of meet their packaging and cooling costs. The primary focus of this tutorial will be on System & RTL level power(More)
A typical multimedia SoC consists of hardware components for image capture & processing, video compression and de-compression, computer vision, graphics and display processing. Each of these components access and compete for the limited bandwidth available in the shared external DDR memory. The traditional solution of using cache is not suitable for(More)
A typical multimedia SoC consists of all or a subset of hardware components for image capture & processing, video compression and de-compression, computer vision, graphics and display processing. Each of these components access and compete for the limited bandwidth available in the shared external memory. Meeting latency (e.g., display) and throughput(More)
