A dynamic scheduler for a computer aided prototyping system

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.
