Contemporary digital systems must be based on the “System-on-Chip — SoC” concept. An interesting style for SoC design is the GALS paradigm (Globally Asynchronous, Locally Synchronous), which can be used to implement circuits in FPGAs (Field Programmable Gate Arrays), but the implementation of asynchronous interfaces (asynchronous wrapper — AW) constitutes a major drawback for this kind of devices...
This paper proposes a new approach for synthesis by direct mapping of extended burst-mode asynchronous finite state machines (XBM_AFSM). The great advantage of the synthesis by direct mapping is the achieved simplicity in methodology, not demanding any knowledge about asynchronous logic concepts, hazard-free circuits and critical race theory. The synthesized XBM_AFSMs operate in mode Ib/Ob, which...
To address the need for evaluation techniques for complex business processes, also known as workflows, this paper proposes an approach based on generalized stochastic Petri nets (GSPNs). We review ten related approaches published in the last fifteen years and compare them to our approach using a wide range of criteria. On the basis of this evaluation, we observe that the newly proposed approach provides...
Contemporary digital systems must necessarily be based on the “System-on-Chip - SoC” concept. An interesting style for SoC design is the GALS (Globally Asynchronous, Locally Synchronous) paradigm, which can be used to implement circuits in FPGAs (Field Programmable Gate Array). Although these devices have the benefits of low-cost and short development time, there's a major drawback which is implementing...
In this work, the problems and respective solutions for dealing with two of the most basic questions regarding handoff management are presented: to avoid total loss of connectivity; and to reduce overall time of the handoff procedure. The focus of this research is on handoff in WPANs for real-time applications. Therefore, Bluetooth stands out as the ideal technology for case study due to its particular...
