Abstract

Structurally adaptive and dynamically reconfigurable systems are presented as important ingredients in the design and development of robust large-scale signal processing systems for operation in complex nonstationary environments. The multigraph programming and execution environment (MPEE) simplifies the design and implementation of such systems because of its graph-based computational model, support for dynamic scheduling, multiprocessor programming capabilities, model-based approach to system design, and graphic editors. The use of MPEE is illustrated by a structurally adaptive system example that highlights both the capabilities of the MPEE and the nature of structurally adaptive and dynamically reconfigurable systems. This example, a signal extraction system, also shows how to deal with transients produced by abrupt changes in filter characteristics of filters during run-time
