SYNTHESISOFLOW-POWER SYNCHRONOUS CONTROLLERS USINGFPGAIMPLEMENTATION
Leonardo Romano · 2008
Today, anumberofdigital systems aredescribed byan architecture consisting ofa network ofsynchronous controllers anddatapaths. Thesearebattery-fed andmay beimplemented inVLSItechnology and/or FPGAs(Field Programmable GateArray). Since thebatteries musthave longlife, reduction ofenergy consumption isthemost important task inthedesign ofsuchsystems. Inorder to reduce dissipated power, anumber ofstrategies havebeen suggested intheliterature forbothcontrollers and datapaths. Inthisarticle we suggest anapproach that applies a new strategy forthesynthesis ofthelowconsumption synchronous controllers. Our method synthesizes synchronous controllers that workatthetwo transition edges ofclock signals, butonlyusesflip-flops that workatasingle clock edge.
