Rapita Systems Ltd., leaders in measurement based worst-case execution time analysis, announce RapiTime 2.0 a comprehensive toolset for performance profiling, and worst-case execution time analysis of real-time embedded software. In the avionics, telecommunications, space, and automotive electronics industries, successful companies know the importance of understanding, verifying, and improving the timing performance of their real-time embedded software. Taking a systematic and scientific approach to ensuring that time constraints are met, allows smart engineers to build timing correctness into their systems rather than spend time and effort trying to get timing bugs out. The result is reduced time to market, combined with class-leading product reliability. Using the new features of RapiTime 2.0 engineers can gain a clear, detailed, and accurate understanding of the execution time behaviour of their real-time software. RapiTime 2.0 uses an Eclipse-based graphical user interface to provide interactive access to a wealth of execution time data, obtained via on-target performance profiling and worst-case execution time analysis. Beyond providing an in-depth understanding of software timing behaviour, RapiTime 2.0 adds the capability to target optimisation effort precisely where it will have the maximum benefit. Using the advanced features of RapiTime 2.0, engineers can discover the extent to which different software components contribute to the worst-case (often very different from their contribution to the average case), identify worst-case hotspots, and select the best opportunities for source code optimisation. RapiTime 2.0 also adds the capability to answer "what-if" questions about achievable performance gains, enabling the headroom for new functionality to be accurately assessed. Exploiting this advanced capability allows engineers to leverage their efforts, obtaining disproportionately large reductions in overall execution times through optimisations targeted at a tiny proportion of the overall software. The result is an elimination of timing overruns, and the efficient creation of headroom for new functionality, without the need for costly and time-consuming hardware upgrades. For further insight into how effective RapiTime is, download a copy of the RapiTime BAE Experience Report. RapiTime is a practical solution that can analyse complex embedded real-time software running on the latest high performance microprocessors. RapiTime 2.0 supports industrial scale C and Ada software from a few kBytes to millions of lines of code. Due to its simple, yet highly effective measurement-based approach, RapiTime 2.0 is compatible with virtually every 8, 16, and 32-bit embedded microprocessor on the market. RapiTime 2.0 supports both automatic software instrumentation and hardware assisted timing trace capture via a logic analyser, or dedicated hardware such as the RapiTime TraceBox. Rapita Systems will be demonstrating the capabilities of RapiTime 2.0 at DATE08 (10th – 14th March 2008, Munich, Germany) on stand S3.
