1. 1. Timing Predictability in Future Multi-Core Avionics Systems

   Författare :Andreas Löfwenmark; Simin Nadjm-Tehrani; Risat Pathan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Timing Predictability; WCET; WCRT; Fault Tolerance; Safety Critical; Avionics;

   Sammanfattning : With more functionality added to safety-critical avionics systems, new platforms are required to offer the computational capacity needed. Multi-core platforms offer a potential that is now being explored, but they pose significant challenges with respect to predictability due to shared resources (such as memory) being accessed from several cores in parallel.

   Sammanfattning : To date, many industrial embedded systems are very large, flexible, and highly configurable software systems, containing millions of lines of code and consisting of hundreds of tasks, many with real-time constraints, being triggered in complex, nested patterns. Furthermore, the temporal dependencies between tasks in such systems are difficult to determine analytically, and they vary the execution time and response time of tasks greatly. LÄS MER
