Research on WCET assessment method of airborne display software

Abstract

Airborne display software WCET assessment relies on actual scenario and traditional static analysis and dynamic test methods can not reflect actual scenario requirements. To achieve WCET value closing to actual scenario for resource saving purpose, firstly the typical architecture of airborne display unit is described; secondly, the worst scenario analysis principles for WCET are identified; thirdly, WCET assessment flow and steps are proposed respectively for non-A661 partition and A661 service partition; lastly, the WCET acceptance principles are given in both software level and system level. This research can help to support airborne display software resource assessment and allocation in the early stage of software design.
