基于FPGA的总线桥接在特种计算机中的应用

摘要

According to the characteristics of multi-interface and miniaturization on special computer, this paper introduced an application of bus bridge technology based on FPGA in the design of special computer. In order to save PCB layout area and space of special computer ,Communication of multiple interfaces and computer power control were designed in a main chip. Many kinds of interface such as Ethernet, UART, USB and CAN BUS were included in the application and it has many advantages such as design flexibility, high stability.%本文针对特种计算机的多接口、微型化特点，以FPGA为核心将总线桥接技术应用于特种计算机设计中，不仅完成计算机电源控制功能，而且以一颗主芯片实现多接口的传输应用，节约PCB布局面积，节省整机空间。该应用包含以太网、UART、USB以及CAN总线等多种接口，设计灵活、稳定性高。
