VXI总线寄存器基器件中断请求器的设计与实现

Design and Realization of VXIbus Interrupt-Requester Based on Register-Based Element

在基于VXI总线的自动测试系统中,中断技术的使用加快了数据传输与处理的速度。文章首先详细地阐述了VXI总线的中断机制,进而提出了一种基于寄存器基器件的中断请求器的设计方案,并给出了硬件电路及软件代码。实际运行表明该设计具有硬件开销小,可移植性强等特点,完全符合VXI总线规范的要求。

The application of interrrupt technology enhances the speed of transmitting data and processing data in the automatic test system lsased on VXIbus.,the interrupt mechanism and the scheme of designing interrupt-requester based on register-based element are expatiated, The interrupt - requester＇ s hardware circuit and software code arc provided. Practice shows the design meets the demamls of VXIbus anti has some characteristies, for example, reducing hardware spending and enhancing the capability of being transplanted .
