摘要：
This paper presents a hardware architecture for supporting distributed real-time operating systems. It proposes the use of dedicated hardware units for running task scheduling and communication, in order to alleviate the load on the processor responsible for running the application tasks. These hardware units also compute the execution time of application tasks, and other statistics that can be taken into account by more sophisticated scheduling algorithms. The proposal enhances the overall system predictability. Since it is based on low-cost microcontrollers, it represents a cost-effective alternative for developing low-cost distributed real-time systems. Copyright (C) 1997 Elsevier Science Ltd.
