Sharing I/O in Strongly Partitioned Real Time Systems

摘要：

Strongly partitioned real-time systems have been adopted to provide an integrated run time environment for applications with varied criticalities.This is achieved by guaranteeing spatial as well as temporal partitioning for the applications. To enable accesses to shared I/O devices in such an environment,this paper provides an effective model that the co-existence of any application does not hinder the execution of IO operations or spatial and temporal requirements of other applications. The model utilizes a microkernel-based approach to regulate the work of drive drivers and thus integrate the device-sharing model with the microkernel.
