| Abstract: | A new integrative fast sampling platform for embedded protection and control equipment is proposed based on an analysis of the limitations of the conventional multi-CPU architecture platform to resolve real-time sampling problems by super-interrupt technology.The hardware and software as well as architecture are discussed,and the key technology of the integrated platform is dealt with at length.The scheme provided has been verified with good results in many engineering projects. |

| Keywords: | protection and control embedded sampling VxWorks PowerPC low voltage differential signal(LVDS) protection interruption |
