Handling Timing Constraints in Rapid Prototyping
MetadataShow full item record
This paper presents the concepts and mechanisms for handling the real-time constraints of embedded software systems in rapid prototyping of embedded systems can be accomplished using a Computer Aided Prototyping System (CAPS) and its associated Prototyping Language (PSDL). This system and language are used to aid the designer in the early stages of software engineering for hard real-time systems. Such systems contain time critical operations with maximum execution times, maximum response times, and minimum calling periods. Interrupt handling, synchronization, and periodic behavior are also described at a high level. Time critical operations in a real-time prototype are handled by constructing static and dynamic schedules to coordinate execution and to meet the required prototype execution times. The mechanisms for expressing time constraints in PSDL are described along with their effects on the schedulers.

To manage and protect critical data in this regard implies that information systems need to enforce temporal security policies. However, ...
