Voltage scaling is an efficient way to reduce dynamic power consumption for digital circuits. In this paper, a hierarchical multiple voltage (HMulti-Vdd) technology is proposed to design a power-aware H.264 intra-frame encoder for wireless panoramic endoscope applications. The proposed design adopts quad supply voltages to reduce power consumption without performance degradation. A progressive voltage...
In this paper we focus on the design methodology to propose a design that is more flexible than ASIC solution and more efficient than the processor-based solution for H.264 video decoder. We explore the memory access bandwidth requirement and different software/hardware partitions so as to propose a configurable architecture adopting a DEM (Data Exchange Mechanism) controller to fit the best tradeoff...
