Two-Level Hazard-Free Logic Minimization of Speed-Independent Extended Burst-Mode Controllers Proceedings Article Oliveira, Duarte L; Faria, Lester A Resumo | Links | BibTeX | Tags: asynchronous logic, finite state machine @inproceedings{Duarte2015finiteb,Several algorithms of hazard-free logic minimization were proposed for extended burst-mode asynchronous controllers that operate in the generalized fundamental mode (GFM) and accept the so-called extended burst-mode (XBM) Specification. This class of controller’s shows to be very interesting because the XBM specification allows describing a wide range of circuits, from complex asynchronous interfaces to Moore-type synchronous controllers that operate in the two edges of the clock signal. Another interesting class of asynchronous controllers is the speed-independent (SI) ones. They are more robusts, more modulate and easy to be verified, when counter-parts. Considering and conjugating the advantages provided by both approaches, in this paper we propose an algorithm for hazard-free logic minimization, exact in the number of literals, for SI asynchronous controllers that starts from the XBM specification, being highly suitable for the implementation on high accuracy, robust and complex systems, like the ones actually embedded in military systems and platforms. The proposed algorithm has been successfully applied to a set of known benchmarks showing good and potential results for practical implementation. |
