FPGA中双向端口I/O的研究

Design of I/O port in FPGA

针对现场可编程门阵列(FPGA)芯片的特点,研究FPGA中双向端口I/O的设计,同时给出仿真初始化双向端口I/O的方法。采用这种双向端口的设计方法,选用Xilinx的Spartan2E芯片设计一个多通道图像信号处理系统。

The I/O port in FPGA is designed based on the characters of FPGA, and gives the simulation mode and initial way of I/O port.Then with this design way of I/O port ,we choose the Xilinx FPGA chip Spartan2E to design a multichannel Video Signal Processing System.
