基于USB接口多位数据格式的高速传输系统

摘要

This design realizes a data transmission system based on USB2.0 interface.The system from the FPGA to produce a 35-bit added to 250 from 0 of the counter,to achieve the value of the counter through the USB to the host computer's function.The design of the FPGA chip uses Altera's CycloneII EP2C5Q208C8N,USB chip Cypress's EZ-USB series CY7C68013A.Through the Quartus II software,Keil software,Cypress console for USB interface design of multi-bit data transmission system.The system can be used for high-precision,high-speed,low-cost bulk data transmission.%该设计实现了一种基于USB2.0接口的数据传输系统.该系统由FPGA产生一个35位自加到250清0的计数器,实现通过USB把计数器的数值传送到上位机的功能.该设计采用的FPGA芯片为Altera公司的CycloneII EP2C5Q208C8N,USB芯片为Cypress公司EZ-USB系列的CY7C68013A.通过Quartus II软件,Keil软件,Cypress控制台进行USB接口多位数据传输系统的设计.该系统可用于高精度、高速度、低成本的批量数据传输.
