Traditional PLC system in the event of system failure, there is no perfect mechanism to ensure the safety of control, the safety PLC based on heterogeneous dual-processor redundant structure can meet the requirements of industrial control for equipment and personnel, improve the reliability of industrial control. In this paper, according to the operation requirements of safety PLC based on heterogeneous...
This paper studies the problem of maximizing multicore system lifetime reliability, an important design consideration for many real-time embedded systems. Existing work has investigated the problem, but has neglected important failure mechanisms. Furthermore, most existing algorithms are too slow for online use, and thus cannot address runtime workload and environment variations. This paper presents...
Heterogeneous MPSoCs consisting of cores with different performance/power behaviors are widely used in many power-constrained real-time systems. Both soft-error reliability and lifetime reliability are key concerns in such systems. Although existing work have investigated related problems, they either focus on one of the two reliability concerns or propose complicated scheduling algorithms that cannot...
Architecture analysis and design language (AADL) is used to describe the hardware and software architectures of embedded applications at the system level. The implementation of such systems is often distributed across asynchronous communication infrastructures. Such a distributed system is usually composed of locally synchronous processes communicating in a globally asynchronous manner, a GALS system...
