Synthesis of Sequential Circuits by using Linearization

The paper deals with synthesis of sequential circuits defined by their algorithmic state machine notation. Such circuits have a number of specific properties which enable efficient design of the circuits by utilizing so-called linearization techniques. A typical linearization technique includes calculation of autocorrelation values for a system of logic functions corresponding to the circuit. For the mentioned sequential circuits, the calculations which usually require massive computational recourses may be significantly reduced and thus low-overhead implementations of the circuits can be obtained relatively easy. The paper introduces a novel architecture of so-called linearized sequential circuits, and a piece-wise linearization approach for synthesis of sequential circuits. Results are evaluated both analytically and by using a number of standard benchmarks.
