Abstract

This paper deals with an iterative decomposition technique that enables implementation of multiple-output Boolean functions as a cascade of look-up tables (LUTs). The heuristics used to find the order of variables in the decomposition is compared with the exhaustive search approach and is found more than satisfactory. A parallel implementation of the decomposition algorithm has been tested on a broad spectrum of randomly generated functions and its scalability has been explored. The by-product of the algorithm is a sub-optimal Multi-Terminal Binary Decision Diagram (MTBDD) of the given function. A clustering algorithm, a follow-up of the decomposition algorithm, has been applied to index-generating functions and LUT cascades optimizing the total memory and/or delay have been found. The use of both algorithms is anticipated in designing application-specific systems.
