介绍了可替代VICx芯片的另外一种VMEbus桥接器件—Tundra公司的SCV64,详细分析了其功能原理、数据传输以及中断处理机制,最后给出了用SCV64构成局部总线到VME总线的接口设计实例,避免了VICx系列芯片所需的多而复杂的外部辅助逻辑,为VME总线系统的设计人员提供了参考。
Abstract:
 Another VMEbus bridge chip—SCV64 from Tundra Semiconductor Corporation is introduced, which can be a substitution of VICx chips. Then the detailed analysis of its function principle , characteristics of data transmission and interrupt mechanism are provided. Finally, a practical example of using SCV64 to implement the interface between local bus and VMEbus is given,which can avoid excessive and complex outer supplementary logic the VICx chip needed and provides reference for the VME bus system designers.
