Real-time scheduling for software prototyping

This paper presents real-time scheduling methods supporting a prototyping language for embedded systems. Rapid prototyping of embedded systems can be accomplished using a Computer Aided Prototyping System (CAPS) and its associated Prototyping Language (PSDL) to aid the designer in handling hard real-time constraints. The prototyping language PSDL is designed based on the real-time model of CAPS. The language models time critical operations with maximum execution times, maximum response times, minimum or fixed periods, and deadlines. Timing constraints in PSDL are described along with scheduling algorithms relative to a series of hardware models used in the CAPS which includes multiprocessor configurations.<
