Reducing Power using Body Biasing in Microprocessors with Dynamic Voltage/Frequency Scaling
Body biasing has been demonstrated to be effective in addressing process variability in a variety of simple chip designs. However, for modern microprocessor ICs with multiple cores and dynamic voltage/frequency scaling (DVFS), the use of body biasing has significant implications. For a 16core chip-multiprocessor implemented in a high-performance 22 nm technology, the body biases required to mee...
متن کاملSupply and Threshold Voltage Scaling for Low Power CMOS
This paper investigates the effect of lowering the supply and threshold voltages on the energy efficiency of CMOS circuits. Using a first-order model of the energy and delay of a CMOS circuit, we show that lowering the supply and threshold voltage is generally advantageous, especially when the transistors are velocity saturated and the nodes have a high activity factor. In fact, for modern subm...
متن کاملSIA Roadmap for Power Dissipation in Current and Future Microprocessors
Increasing levels of power dissipation threaten to limit the performance gains of future high-end, out-of-order issue microprocessors. Therefore, it is imperative that designers devise techniques that significantly reduce the power dissipation of the key hardware structures on the chip without unduly compromising performance. Such a key structure in out-of-order designs is the issue queue. Alth...
متن کاملInstruction Scheduling for Low Power Dissipation in High Performance Microprocessors
Power dissipation is rapidly becoming a major design concern for companies in the high-end microprocessor market. The problem now is that designers are reaching the limits of circuit and mechanical techniques for reducing power dissipation. Hence, we must turn our attention to architectural approaches to solving this problem. In this work we propose a method of instruction scheduling which limi...
متن کاملOptimal DG Placement for Power Loss Reduction and Improvement Voltage Profile Using Smart Methods
Distributed Generations (DGs) are utilized to supply the active and reactive power in the transmission and distribution systems. These types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. In order to reach the above benefits, the optimal placement and sizing of DG is...
