The use of dual threshold voltages can significantly reduce the static power dissipated in CMOS VLSI circuits. With the supply voltage at 1V and threshold voltage as low as 0.2V the subthreshold leakage power of transistors starts dominating the dynamic power. Also, many times a large number of devices spend a long time in a standby mode where the leakage(More)
Dynamic power consumed in CMOS gates goes down quadratically with the supply voltage. By maintaining a high supply voltage for gates on the critical path and by using a low supply voltage for gates off the critical path it is possible to dramatically reduce power consumption in CMOS VLSI circuits without performance degradation. Interfacing gates operating(More)
Transitions on high capacitance buses in VLSI systems result in considerable power dissipation. Various coding schemes have been proposed in the literature to encode the input signal in order to reduce the number of transitions. Reducing number of transitions comes in exchange for redundancy in data transferred over the buses. For a given amount of(More)
A novel low-power synthesis technique is presented for the design of folded or time-multiplexed programmable-coefficient FIR filters where storage area is traded-off for lowering power consumption. A systematic technique is developed for low power mapping of FIR filters to architectures with arbitrary number of multipliers and adders. Power consumed in(More)
In this paper we propose an efficient technique for energy savings in DSM technology. The core of this method is based on low-voltage signaling over long on-chip interconnect with repeaters insertion to tolerate DSM noise and to achieve an acceptable delay. We elaborate a heuristic algorithm, called VIJIM, for repeaters insertion. VIJIM algorithm has been(More)
This paper presents MINFLOTRANSIT, a new transistor sizing tool for fast sizing of combinational circuits with minimal cost. MINFLOTRANSIT is an iterative relaxation based tool that has two alternating phases. For a circuit with |<italic>V</italic>| transistors and |<italic>E</italic>| wires, the first phase <italic>(D-phase)</italic>) is based on minimum(More)
