基于FPGA的串行通讯接口设计

Design of Serial Communication Interface Based on FPGA

随着机载设备的快速发展,设计需求日益复杂多样,机载设备往往需要在不增加硬件资源的情况下适应多种设备和接口。简要介绍了复杂可编程器件的开发流程,重点讨论了串行通讯接口的模块化设计思路及具体实现方法,给出了仿真结果。设计采用Xilinx公司的Virtex-4系列FPGA芯片,仿真结果表明满足协议要求。

With the improvement of avionics,the requirements for design become more and more complex,how to communicate with multiple interfaces without more hardware is a key problem. The developing flow of FPGA is introduced,a modularization design method of serial communication interface is discussed in detail,and also the simulation result is given. Virtex- 4 FPGA of Xilinx is selected and the simulation result shows that the design result is acceptable.
