— IEC 61499 has been endorsed as the standard for modelling and implementing distributed industrial-process measurement and control systems. The standard prescribes the use of function blocks for designing systems in a component-oriented approach. The execution model of a basic function block and the manner for event/data connections between blocks are(More)
Reactivity on external events is an important feature of almost all embedded systems. In this paper we present the design of a new, reactive embedded microprocessor called REMIC, that supports reactivity in a new way following the paradigm of synchronous system level language Esterel. The rationale for REMIC design, its novel features with the design(More)
Esterel is a system-level language for the modelling, verification and synthesis of control dominated (reactive) embedded systems. Existing Esterel compilers generate intermediate C code that is subsequently mapped to a suitable target processor. The generated code emulates the reactive features of the language due to lack of support for these features on(More)
In this paper we present the syntax, semantics, and compilation of a new system-level programming language called SystemJ. SystemJ is a multiclock language supporting the Globally Asynchronous Locally Synchronous (GALS) model of computation. The synchronous reactive (SR) model is used for synchronous parts of the modelled system, and those parts, which(More)
In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of(More)
—Recursive-least-square (RLS) algorithm is widely used in many areas with real-time implementation using digital signal processors. In this paper, the authors present a pure hardware implementation of a self-tuning regulator (STR) that uses a real-time RLS algorithm as the parameter estimator. The STR contains a controller design circuit and a controller(More)
