摘 要：介绍了一种利用CY7C68013的通用可编程接口（GPIF）访问TMS320VC5402内部存储器的方法。应用Cypress公司开发的GPIF波形设计器设计了用单字节写方式控制主机接口（HPI）内部寄存器、用FIFO读/写方式读/写DSP内部RAM的3种控制波形，并在此基础上着重分析了读/写DSP内部RAM的GPIF波形时序。最后，介绍了相应的固件程序设计和设备驱动设计，并把该方法应用于信号发生器输出信号的采集，验证了该方法的可行性。

Abstract: A method which used CY7C68013s GPIF interface to access the TMS320VC5402 onchip memory was introduced. By using the GPIF designer exploit of Cypress company, three control waveforms, singlewrite transaction waveform to control host port interface (HPI) registers, FIFOread and FIFOwrite transactions waveform to access the TMS320VC5402 onchip memory were designed, and GPIF waveform timing of access DSP onchip RAM was analyzed in detail. Besides, the relevant firmware and device driver program were also designed. Finally, with a data acquisition application, the interface designed is validated.
Key words: USB2.0; host port interface (HPI); general programmable interface (GPIF); drivers
