Low Power Optimization Techniques for BDD Mapped Finite State Machines

Low-power optimization techniques for BDD mapped circuits using temporal correlation Techniques d’optimisation pour les faibles puissances pour des diagrammes de décision binaire utilisant la corrélation temporelle

In modern design flows low-power aspects should be considered as early as possible to minimize power dissipation in the resulting circuit. A new binary decision diagram–based design style that considers switching activity optimization using temporal correlation information is presented. The technique is based on an approximation method for switching activity estimation. In the case of finite st...

Switching activity estimation of finite state machines for low power synthesis

A technique for computing the switching activity of synchronous Finite State Machine (FSM) implementations including the influence of temporal correlation among the next state signals is described. The approach is based upon the computation that a FSM is in a given state which, in turn, is used to compute the conditional probability that a next state bit changes given its present state value. A...

Finite State Machines with Datapath

Resent investigations have shown the very good results of digital systems and circuits optimization using integration of dynamic power management in the design flow. This approach proceed from detection periods of time during which parts of the circuit are not doing useful work and shut them down by either turning off the power supply or the clock signal. In this work, we take this approach to ...

Power Optimization using Dynamic Power Management

Power dissipation has recently emerged as one the most critical design constraints. A wide range of techniques has already been proposed for the optimization of logic circuits for low power. Power management methods are among the most effective techniques for power reduction. These methods detect periods of time during which parts of the circuit are not doing useful work and shut them down by e...
