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。 A method which used CY7C68013's GPIF interface to access the TMS320VC5402 on-chip memory was introduced. By using the GPIF designer exploit of Cypress company, three control waveforms, single-write transaction waveform to control host port interface (HPI) registers, FIFO-read and FIFO-write transactions waveform to access the TMS320VC5402 on-chip memory were designed, and GPIF waveform timing of access DSP on-chip 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.
