RAPID RMA: The Art of Modeling Real-Time Systems

Using Rate Monotonic Analysis (RMA), RAPID RMA (formerly PERTS, Prototyping Environment for Real-Time Systems) helps real-time systems software developers prevent costly design mistakes and accelerate their development schedules. The multiple analysis tools contained in RAPID RMA 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, RAPID RMA can save thousands of dollars and avoid many hours of wasted manpower.

"Our systems need to meet explicit quantitative performance goals. If you miss a timing sequence when designing a satellite, it falls out of the sky. RMA-based tools are the only ones that can perform the sophisticated technical analysis we need to assure quality real-time system design."
- Lockheed Martin

RAPID RMA is based on research conducted at the University of Illinois at Urbana-Champaign.
