A new language, Feldspar, is presented, enabling high-level and platform-independent description of digital signal processing (DSP) algorithms. Feldspar is a pure functional langua...
In static analysis, the semantics of the program is expressed as a set ions. The equations are solved iteratively over some abstract domain. If ract domain is distributive and sati...
We present four constructions for standard equipment which can be generated for every inductive datatype: case analysis, structural recursion, no confusion, acyclicity. Our constru...
Processor obsolescence is a serious maintenance problem for long-lived embedded control systems. A practical solution is to interpose an emulator program between the ‘legacy’ s...
In this paper we discuss the question which properties of a formally verified component are preserved when the component is changed due to an adaption to a new use. More specific...
