Abstract

We present a method that enables an efficient implementation of the approximative response time analysis for tasks with offsets presented by Tindell and Palencia Gutierrez et. al.The method utilises the fact that the interference a transaction imposes on a lower priority task exhibits a periodic and static pattern. This pattern can be pre-computed in a table, reducing the fix-point calculations to a simple lookup-up function. We show by simulations that the speed-up is substantial, and for realistically sized task sets, more than 600 times, compared to the original analysis.
