The new generation of embedded systems for automotive applications can take advantage of low-cost multipro-cessor system-on a chip architectures. The real-time software applications running on these systems require real-time processor scheduling, and also require the management of the communication and synchronization of tasks executing on different(More)
Ethernet was not originally developed to meet the requirements of real-time industrial automation systems and it was commonly considered unsuited for applications at the field level. Hence, several techniques were developed to make this protocol exhibit real-time behavior, some of them requiring specialized hardware, others providing soft-real-time(More)
Scheduling theory generally assumes that real-time systems are mostly composed of activities with hard real-time requirements. Many systems are built today by composing different applications or components in the same system, leading to a mixture of many different kinds of requirements with small parts of the system having hard real-time requirements and(More)
Next generation embedded systems will demand applications with increasing complexity, that a standard uniprocessor microcontroller architecture will likely be unsuited to support. A possible solution to cope with embedded applications with high computational requirements is to adopt multiple-processor-on-a-chip architec-tures. This paper discusses the(More)
