The State Assignment of Finite State Machine for Minimizing the Power Dissipation
Języki publikacji
Abstrakty
Opisano badania trzech algorytmów kodowania stanów wewnętrznych automatu skończonego: algorytmu kodowania kolumnowego, algorytmu "wyżarzania" oraz algorytmu sekwencyjnego. Głównym zadaniem wymienionych algorytmów jest zakodowanie stanów wewnętrznych automatu skończonego w taki sposób, aby moc pobierana przez automat skończony była jak najmniejsza. Badania eksperymentalne, które przeprowadzono na standardowych układach testowych, potwierdziły wyższość opracowanego przez autorów algorytmu sekwencyjnego.
The reduction of the power dissipation is of extreme importance for mobile, battery-operated systems as well as for increasing the speed and performance of the digital systems. Based on the CMOS gate model we can prove that power dissipation depends on the applied assignment. Thus using the particular state assignment method lead to minimization of the power dissipation. In this paper three algorithms of the FSM internal states assignment were described: column-based, annealing and sequential. The main aim of those algorithms were to minimize the power dissipation in the sequential circuits by assigning the state codes with as minimal Hamming distance as possible. Experimental results show that sequential algorithm can reduce about 10% more power than other discussed algorithms.
