一种CCDL的FPGA设计与实现
Design and Implementation of Cross Channel Data Link on FPGA
摘要
Abstract
The vehicle management system requires the highest security,ascertainment and reliability in future,and the redundancy tech-nique can satisfy the system's requirement. But the Cross Channel Data Link ( CCDL) is important for data and information exchange a-mong redundancy computers. Also it is a key component to guarantee the redundancy vehicle management computer's normal operation. Based on the system's performance demands of treble-redundancy plane management,the structure of the CCDL hardware logic design is given. Then the key functions of the CCDL are analyzed and designed. An cross channel data link which transmits reliably by point to point and prevents from fault spread on the 1394 bus is designed,and the CCDL is realized and validated on FPGA. The experiment re-sults indicate that the CCDL design can fulfill the system application requests with the high efficiency and reliability.关键词
