| Abstract: | This paper is based upon a kind of Fault-tolerant Real-time Distributed Computer System (FT-RTDCS)architecture which is built on high-powered and reliable node computers and dual redundancy networks.Emphasis is put on the study of Real-time Distributed Supporting Platform(FT-DSP),which works between the real-time applications and hardware platform of FT-RTDCS.To overcome difficulties of implementation,the predictable mechanism is analyzed and an implementation scheme of FT-DSP is given to support hard real-time tasks,soft real-time tasks and non real-time tasks in FT-RTDCS. |
