Low power has emerged as a principal theme in today's electronics industry. The need for low power has caused a major paradigm shift in which power dissipation is as important as performance and area. This article presents an in-depth survey of CAD methodologies and techniques for designing low power digital CMOS circuits and systems and describes the many(More)
This paper presents an intra-process dynamic voltage and frequency scaling (DVFS) technique targeted toward non real-time applications running on an embedded system platform. The key idea is to make use of runtime information about the external memory access statistics in order to perform CPU voltage and frequency scaling with the goal of minimizing the(More)
In many new high performance designs, the leakage component of power consumption is comparable to the switching component. Reports indicate that 40% or even higher percentage of the total power consumption is due to the leakage of transistors. This percentage will increase with technology scaling unless effective techniques are introduced to bring leakage(More)
The growing packing density and power consumption of VLSI circuits have made thermal effects one of the most important concerns of VLSI designers. The increasing variability of key process parameters in nanometer CMOS technologies has resulted in larger impact of the substrate and metal line temperatures on the reliability and performance of the devices and(More)
This paper describes a dynamic voltage and frequency scaling (DVFS) technique for MPEG decoding to reduce the energy consumption while maintaining a quality of servic(QoS) constraint. The computational workload for an incoming frame is predicted using a frame-based history so that the processor voltage and frequency can be scaled to provide the exact amount(More)
Liquid Crystal Displays have appeared in applications ranging from medical equipment to automobiles, gas pumps, Laptops and handheld portable computers. These display components present a cascaded energy attenuator to the battery of handheld device which is responsible for about half of energy drain at maximum display intensity. As such, the display(More)
We present a dynamic programming technique for solving the multiple supply voltage scheduling problem in both non-pipelined and functionally pipelined data-paths. The scheduling problem refers to the assignment of a supply voltage level to each operation in a data ow graph so as to minimize the average energy consumption for given computation time or(More)
This paper presents a theory for (disjunctive and nondisjunctive) function decomposition using the BDD representation of Boolean functions. Incompletely specified as well as multi-output Boolean functions are addressed as part of the general theory. A novel algorithm (based on an EVBDD representation) for generating the set of all bound variables that make(More)
