Overview
Embedded systems are informally defined as a collection of programmable parts surrounded by ASICs and other standard components, that interact continuously with an environment through sensors and actuators. The programmable parts include micro-controllers and Digital Signal Processors (DSPs).
Embedded systems are often used in life-critical situations, where reliability and safety are more important criteria than performance. Today, embedded systems are designed with an ad hoc approach that is heavily based on earlier experience with similar products and on manual design. Use of higher-level languages such as C helps structure the design somewhat, but with increasing complexity it is not sufficient. Formal verification and automatic synthesis of implementations are the surest ways to guarantee safety.
Thus, the POLIS system which is a co-design environment for embedded systems is based on a formal model of computation.
POLIS was initiated in 1988 as a research project at the University of California at Berkeley and, over the years, grew into a full design methodology with a software system supporting it.
Hardware-Software Co-Design of Embedded Systems: The POLIS Approach is intended to give a complete overview of the POLIS system including its formal and algorithmic aspects.
Hardware-Software Co-Design of Embedded Systems: The POLIS Approach will be of interest to embedded system designers (automotive electronics, consumer electronics and telecommunications), micro-controller designers, CAD developers and students.

Originating from a 1988 meeting at Magneti Marelli, a major European producer of automotive electronic subsystems, the POLES project headed by Balarin (Cadence Berkeley Labs; Berkeley, CA), developed into a research methodology and supporting software for solving complex design challenges. Along with colleagues from Italy and Japan, the Berkeley scientists discuss the importance and design of embedded systems, models and representations, synthesis, interface synthesis and the real-time operating system, verification, interfacing to external hardware and software, design examples, the syntax of SHIFT, and future directions. A glossary is included. What POLES stands for remains a mystery. Annotation c. by Book News, Inc., Portland, Or.
