设计实现了以FPGA为主控制单元,采用EZ-USB FX2微处理器为接口芯片的快速数据传输系统。文章给出了FPGA和CY7C68013之间数据传输的软硬件设计方案,着重介绍了FPGA内部建构的FIFO原理及程序实现方法,并以FLASH存储模块为例,通过FX2与FLASH握手过程的设计,实现了数据存储器与计算机之间的数据高速传输。应用结果表明,此数据传输系统可靠有效,具有一定的通用性,可用于其他使用USB进行数据传输的系统中。
Design and implementation of a FPGA-based control unit, the use of EZ-USB FX2 microprocessor interface chip for fast data transfer system. The article gives the hardware and software design scheme of data transmission between FPGA and CY7C68013, emphatically introduces the FIFO principle and program implementation method built in FPGA, and take FLASH memory module as an example, through the design of the handshake process of FX2 and FLASH, High-speed data transfer between data storage and computer. The application results show that this data transmission system is reliable and effective and has some commonality and can be used in other systems that use USB for data transmission.
