RapiTime Worst-Case Execution Time Technology

Research from the Real-Time Systems Group at the University of York resulted in an innovative Worst-Case Execution time (WCET) analysis technology now called RapiTime, which was transferred to industry via a spin-out company, Rapita Systems Ltd.

The technology enables companies in the aerospace, space and automotive industries to reduce the time and cost required to obtain confidence in the timing correctness of the systems they develop. The RapiTime technology has global reach having been deployed on major aerospace and automotive projects in the UK, Europe, Brazil, India, China, and the USA. Key customers include leading aerospace companies as well as major automotive suppliers.
