“…In order to eliminate the problem of logic minimization, which has to be free of logical hazard, and the limitation of the BM specification, which does not accept signals LSS, Oliveira et al [9] proposed a state assignment technique for XBM_AFSM with local clock in the Huffman architecture with output feedback. Then, Curtinhas et al [10] implemented the states assignment technique of [9] using genetic algorithm. The paper of [9] proposed an architecture with local clock based on flip-flops, focusing on FPGA platforms.…”

“…It follows the conventional steps of logic synthesis and starts from the XBM specification. As in [9][10][11], the only restriction is not accepting the "directed don't-care" signals of the XBM specification. The steps of transforming the XBM specification in a Kiss2 description and generation and analysis of the dependency graph are performed by the proposed XBM_DG tool.…”

⎯ Controllers based on Synchronous Finite State Machines (SFSM) are widely used in the control unit design of complex digital systems. These systems can present serious problems related to the global clock. In this context, the asynchronous paradigm shows interesting features that fit as an alternative for the design, despite of the difficulties of the application of asynchronous logic. An interesting architecture for the Asynchronous Finite State Machines Asynchronous (AFSM) is based on local clock, because it reduces the requirements of asynchronous logic. This paper proposes a new architecture of local clock to AFSMs, which is described by a popular specification known as Extended Burst-Mode (XBM). This architecture has a better cycle time when compared to other local clock architectures. Also, the paper proposes a "necessary and sufficient" condition for the local clock AFSMs on the proposed architecture to be synthesized completely by the use of conventional tools. Through a case study, we present the architecture, its robustness, the synthesis procedure and compare it with other local clock architectures, highlighting its advantages.
