Design of virtual digital controllers based on dynamically reconfigurable FPGAs

The paper discusses dynamically reconfigurable FPGAs and their use for the physical implementation of digital controllers. The technique considered presents various ways of behavioral specification and logic synthesis, which can be applied to the practical design of virtual control circuits that have such properties as flexibility, extensibility and reusability. The authors have suggested the basic structure of a virtual digital controller that is composed of a formally synthesized modifiable circuit (specified by either graph-schemes or their extensions) and reusable functional blocks that are invoked in order to simplify, the description of the control algorithms
