A dynamic scheduler for a computer aided prototyping system

de Susan L. Eaton

Current software development methodologies have proven to be ineffective for meeting the rising demand for fast production of reliable software for hard real-time computer systems. A computer-aided, rapid prototyping system (CAPS) based on a Prototype System Description Language (PSDL) and a set of software tools including an Execution Support System (ESS), has been proposed by other research and provides a promising and cost effective alternative to the traditional development life cycle of these systems. This study proposes a four function design for the dynamic scheduler of the CAPS ESS. This design includes a method for invoking processes for the ESS static scheduler and translator, a scheduling algorithm for the scheduling of the prototype's non-time critical processes, and a method for error and interrupt handling during prototype execution.
