Transient power minimization through datapath scheduling in multiple supply voltage environment
نویسندگان
چکیده
In designs for battery driven portable applications, the reduction of peak power, peak power differential, average power and energy are equally important. In [1], a parameter called ”cycle power pro£le function” is de£ned that captures the above power parameters and a heuristic algorithm is proposed using multiple voltages and dynamic clocking for its minimization. In this paper, we rede£ne the CPF, denoted as CPFMC for multiple voltages and multicycling (MVMC). Then, we modify nonlinear CPFMC to facilitate its minimization using ILP through datapath scheduling. Experiments conducted for various high level synthesis bechmarks reveal signi£cant reductions in all power parameters alongwith.

We model the power fluctuation as cycle-to-cycle power gradient and minimize the mean of the power gradients using ILP. We propose scheduling schemes for three modes of datapath design : single supply voltage and single frequency (SVSF), multiple supply voltages and dynamic frequency clocking (MVDFC), and multiple supply voltages and multicycling (MVMC). Various experiments are conducted on sel...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...
