High-speed digital signal processing and control

Article Abstract:

A framework based on the delta operator as the basic dynamical element in the representation of signals and systems is a novel approach for solving digital signal processing and control problems. A systems calculus allowing for the unification and discrete time formulations for signal processing and control problems is the result of this approach. The systems calculus provides for a smooth transition from sampled-data algorithms to their continuous-time counterparts, and the result is enhanced numerical conditioning of high-speed regime algorithms. Applications for this formulation include problems of system state estimation, system identification and time-series modeling and digital control system design. Other applications include wide-band communications and digital control.

Programming real-time applications with SIGNAL

Article Abstract:

The SIGNAL programming language, and its compiler, are described. SIGNAL is based on synchronous principles and is designed to provide safe, real-time system programming. A mathematical model of multiple-clocked flows of events and data defines SIGNAL's semantics. The language's programs describe the relations for such objects, making it possible to program a real-time application via constraints. The compiler's calculation of system solutions makes it useful as a proof system and is a natural way to derive a program's multiprocessor executions. SIGNAL provides the programmer with an intuitive, block-diagram-style graphical user interface. SIGNAL is described in detail.
