CDFG-Petri net temporal partitioning for switching context applications

Reconfigurable computing has made promising progress. The development of platforms that match the reconfigurable hardware with programmable elements, such as DSPs or microprocessors, promise great applicability in diverse areas in the future. In this article, we describe a co-design methodology for single-context and virtual hardware applications based on Petri nets for the PISH design environment. A platform description is presented as well as the reconfiguration methodology. A temporal partitioning is described, exploring different solutions for different applications with time and communication constraints.
