Abstract [en]

Finite state machine (FSM) partitioning proves effective for power optimization. In this paper we propose a design model based on mixed synchronous/asynchronous state memory that results in implementations with low power dissipation and low area overhead for partitioned FSM.s. The state memory here is composed of the synchronous local state memory and asynchronous global state memory, where the former is used to distinguish the states inside a sub-FSM, and the latter is responsible for controlling sub-FSM communication. The input and output behaviour of the decomposed FSM is cycle by cycle equivalent to the undecomposed synchronous FSM. Together with clock gating technique, substantial power reduction can be demonstrated.

Abstract [en]

An efficient way to obtain Finite-State Machines (FSMs) with low power consumption is to,partition the machine into two or more sub-FSMs and use dynamic power management, where all sub-FSMs not active are shut down, to reduce dynamic power dissipation. In this paper we focus on FSM partitioning algorithms and RT-level power estimation functions that are the key issues in the design of a CAD tool for synthesis of low-power partitioned FSMS. We target an implementation architecture that is based on both synchronous and asynchronous state memory elements that enables larger power reductions than fully synchronous architectures do. Power reductions of up to 77% have been achieved at a cost of an increase in area of 18%.
