The Spring System: Integrated Support for Complex Real-Time Systems

The Spring system is a highly integrated collection of software and hardware that synergistically operates to provide end-to-end support in building complex real-time applications. In this paper, we show how Spring's specification language, programming language, software generation system, and operating system kernel are applied to build a flexible manufacturing testbed. The same ingredients have also been used to realize a predictable version of a robot pick and place application used in industry. These applications are good examples of complex real-time systems that require flexibility. The goal of this paper is to demonstrate the integrated nature of the system and the benefits of integration; in particular, the use of reflective information and the value of function and time composition. The lessons learned from these applications and the project as a whole are also presented.     

An experiment in language design for distributed systems

This paper describes a recent experiment in the design, implementation and application of a programming language designed specifically for distributed systems. The fundamental nature of such systems is used in the derivation of an experimental language, which is described and illustrated. Having outlined an implementation, the project is evaluated and some of the more significant findings are reported. In particular, the paper discusses (and argues for) an explicit language facility for expressing the distribution of a program over an actual system.

Testing syntax and semantic coverage of Java language compilers

Software testing is a critical and important stage of the application software development life-cycle. Testing is a verification activity that affects the overall software quality. The verification of critical and dependable computer software such as real-time safety-critical software systems consumes about 50% of the project time. In this work, we consider testing compilers. Since a compiler is a highly usable software, an increased emphasis on reliability requires a careful testing before releasing the compiler. In compiler testing, the compiler implementation is verified to conform to the specified language syntax and semantic available in the standard language documentation. In this work, an algorithm is designed and a tool is developed to automate the generation of test cases to check the language syntax. In addition, we propose a heuristic approach to cover language semantics. Since Java is a relatively new programming language, we concentrate on testing the adherence of new Java compilers to the language syntax and semantics.     

The making of the MCM/70 microcomputer

MCM/70, manufactured by Micro Computer Machines (MCM), was a small desktop microcomputer designed to provide the APL programming language environment for business, scientific, and educational use. MCM was among the first companies to fully recognize and act upon microprocessor technology's immense potential for developing a new generation of cost-effective computing systems. This article discusses the pioneering work on personal microcomputers conducted at MCM in the early 1970s and, in particular, the making of the MCM/70 microcomputer.
