摘要
为了实现DSP调试系统中数据和指令在DSP和主机之间的传输,利用EZ-USB FX2芯片,设计了一个满足DSP调试系统应用需求的数据传输系统。重点介绍了FX2芯片结构和Slave FIFO,并进一步给出了硬件电路、USB固件程序、驱动程序以及主机应用程序的设计方法。实践结果表明,该系统运行稳定可靠,具有较高的应用价值。
The article designed a data transfer system for DSP debugging system by using EZ-USB FX2 chip in order to solve the problem of data and command transfer between DSP and the host. It introduces the chip structure of FX2 and the Slave FIFO, and also brings forward the designing methods of hardware, USB firmware, driver program and application software. Practice results show that the system runs stably and reliably, and has a good application value.
