In many safety-critical missions, more and more Multiprocessor Embedded Systems are used to provide the ability of fault tolerance. Using Operating System can easy software design and make software development more efficient. Because of the limited resource in Embedded Systems, many advanced technologies used in common desktop multiprocessor environment have not been used in Embedded RTOS yet. In this paper, we introduce the technologies of Virtual CPU Pool and Multiprocessor Processor Communication Interface to solve task distributing and communication between deferent CPUs. After using and mending uC/OS, I finally realize and test an Operating System in a kind of SMP multiprocessor hardware module successfully.
A Novel Implementation of Hardware Based Hybrid Embedded RTOS
