Time-predictable resource sharing for commercial-off-the-shelf embedded architectures

点击翻译按钮获取中文摘要

Embedded systems are moving from federated architectures, where logical applications and subsystems are implemented on different hardware components, to progressively more integrated platforms which use extensive sharing of physical resources such as CPU time, memories, and power. Furthermore, they are increasingly built using Commercial-Off-The-Shelf (COTS) components in an attempt to increase performance and reduce cost and time to market. However, integrating COTS in safety-critical systems such as those in the medical, avionics and automotive industry is challenging. These systems require strict timing guarantees and isolation between subsystems to safely interact with the environment, but COTS are not typically designed with such objectives in mind.
