We ... WebThe foremost requirement for real-time system virtualiza-tion is ensuring timing predictability. Hierarchical real-time scheduling theory [12, 31, 35, 36, 46] and its implementa-tions [18, 45, 22] have established a good foundation for this requirement. However, shared hardware resources on recent multi-core platforms, such as a last-level ...

WebJan 1, 1998 · The problem with using traditional hardware-managed caches in real-time systems is that they provide a probabilistic performance boost; a cache may or may not … WebSep 21, 2024 · A small but critical clarification explains why there are no simple solutions to this problem. If Service A writes to its database and then sends a notification to a queue for Service B (let’s call it a local-commit-then-publish approach), there is still a chance the application won't work reliably.While Service A writes to its database and then sends the …
WebNov 3, 2015 · Nevertheless, a review and categorization of these techniques is still an open topic and would be very useful for the real-time community. In this article, we present a survey of cache management techniques for real-time embedded systems, from the first studies of the field in 1990 up to the latest research published in 2014. WebIn this work, abstract interpretation is applied to the problem of predicting the cache behavior of programs. Abstract semantics of machine programs are defined which determine the contents of caches. For interprocedural analysis, existing methods are examined and a new approach that is especially tailored for the cache analysis is presented.
WebThere are two alternatives: a real-time cache (a software-managed fully associative cache with extremely large cache blocks) and a virtually addressed cache. To address capacity misses, one can dynamically (and predictably) manage the cache contents. Introduction Real-time embedded systems require guaranteed performance behavior because they ...
