RapidRMA

Using Rate Monotonic Analysis (RMA), RapidRMA, formerly known as PERTS (Prototyping Environment for Real-Time Systems) and RapidSim allow real-time systems software developers to prevent costly design mistakes and accelerate their development schedules. The multiple analysis tools contained in RapidRMA allow designers to test software models against various design scenarios and evaluate how different implementations might optimize the performance of their systems. By isolating and identifying potential scheduling bottlenecks in both soft and hard real-time systems, RapidRMA can save thousands of dollars and avoid many hours of wasted manpower.

RapidRMA and RapidSim are based on research conducted at the University of Illinois at Urbana-Champaign. RapidRMA implements the object oriented resource contention protocol, Distributed Affected Set Priority Ceiling Protocol (DASPCP), developed by the University of Rhode Island and SPAWAR.

Benefits:

• Allows cost effective testing and modeling of systems
• Guarantees schedulability under "worst-case" conditions Isolates and identifies timing problems
• Reduces development time and cost
• Provides "what if " support to identify bottlenecks and performance issues
• Provides "worst-case" schedulability analysis
