244 results about "Testbed" patented technology

A testbed (also spelled test bed) is a platform for conducting rigorous, transparent, and replicable testing of scientific theories, computational tools, and new technologies. The term is used across many disciplines to describe experimental research and new product development platforms and environments. They may vary from hands-on prototype development in manufacturing industries such as automobiles (known as "mules"), aircraft engines or systems and to intellectual property refinement in such fields as computer software development shielded from the hazards of testing live.

Methods and arrangements for unified program analysis

A unified program analysis framework that facilitates the analysis of complex multi-language software systems, analysis reuse, and analysis comparison, by employing techniques such as program translation and automatic results mapping, is presented. The feasibility and effectiveness of such a framework are demonstrated using a sample application of the framework. The comparison yields new insights into the effectiveness of the techniques employed in both analysis tools. These encouraging results yield the observation that such a unified program analysis framework will prove to be valuable both as a testbed for examining different language analysis techniques, and as a unified toolset for broad program analysis.
