"abstract": "<p>The safety critical industry is considering a shift from single-core COTS to multi-core COTS processors for safety and time critical computers in order to maximize performance while reducing costs. In a domain where time predictability is a major concern due<br>\nto the regulation standards, multi-core processors are introducing new sources of time variations due to the electronic competition<br>\nwhen the software is accessing shared hardware resources, and characterized by timing interference. The solutions proposed in the literature to deal with timing interference are all proposing a trade-off between performance efficiency, time predictability and&nbsp; intrusiveness in the software. Especially, none of them is able to fully exploit the multicore efficiency while allowing untouched,&nbsp; already-certified legacy software to run. In this paper, we introduce and evaluate BB-RTE, a Budget- Based RunTime Engine for Mixed &amp; Safety Critical Systems, that especially focuses on mixed critical systems. BB-RTE aims at guaranteeing the deadline of high-critical tasks 1) by computing for each shared hardware resource a budget in terms of extra accesses that the critical tasks can support before their runtime is significantly impacted; 2) by temporarily suspending low-critical tasks at runtime once this budget has been consumed.</p>",
