A low power state assignment algorithm for asynchronous circuits using a state transistion probability
상태천이확률을 이용한 비동기회로의 저전력 상태할당 알고리즘
Abstract
In this paper, a new method of state code assignment for reduction of switching activities of state transition in asynchronous circuits is proposed. The algorithm is based on a on-hot code and modifies it to reduce switching activities. To estimate switching activities as a cost functions we introduce state transition probability (STP). AS a results, the proposed algorithm has an advantage of 60% over with the conventional code assignment in terms of switching and code length of state assignment.
