Network-on-Chip (NoC) is a preferred communication medium for massively parallel platforms. Fixed-priority based scheduling using virtual-channels is one of the promising solutions to support real-time traffic in on-chip networks. Most of the existing NoC implementations which can support fixed-priority based scheduling use a flit-level preemptive scheduling. Under such a mechanism, preemptions can...
Today's automotive embedded systems comprise a multitude of functionalities, many with complex timing requirements. Besides task specific timing requirements, such applications often have timing requirements for the propagation of data through a chain of tasks. An important metric for control applications is the data age, which is addressed in this paper. The analysis of such systems is non-trivial...
To maintain, analyze and reuse many of today's Complex Real-Time Embedded Systems (CRTES) is very difficult and expensive, which, nevertheless, offers high business value in response to great concern in industry. In such context, not only functional behavior but also non-functional properties of systems have to be assured, i.e., Worst-Case Response Time (WCRT) of tasks has to be known. However, due...
