本文介绍了用大规模可编程逻辑器件设计和实现ＶＸＩ总线消息基接口芯片。该接口芯片具有中断ＲＯＲＡ、Ａ１６／Ｄ１６、Ａ２４／Ｄ３２及块传输能力，传输速率高达２０ＭＢ／ｓ。由于采用可重配置可编程逻辑器件，故很易实现ＶＸＩ总线Ａ３２／Ｄ３２的能力。
This article describes the design and implementation of VXI bus message-based interface chips using large-scale programmable logic devices. The interface chip with interrupt RORA, A16 / D16, A24 / D32 and block transfer capabilities, transfer rates up to 20MB / s. The VXI bus A32 / D32 is easy to implement thanks to the reconfigurable programmable logic device.
