利用FIFOs实现USB与DSP的高速数据传输

Using FIFOs to Realize the High-Speed Data Transmission between USB and DSP

利用两片SN74V245实现了TMS320C6201与EZ-USBFX2LP系列芯片CY7C68013A的连接,介绍了TMS320C6201的外部存储接口(EMIF)和CY7C68013A的通用可编程接口(GPIF)以及它们与SN74V245的连接方案,深入研究了GPIF的波形描述符编写和固件程序开发。

Using two SN74V245 FIFOs as an interface realized the connectivity between TMS320C6201 and CY7C68013A. TMS320C6201,s External Memory Interface (EMIF)and CY7C68013A,s General Programmable Interface (GPIF) are introduced, their hardware connections to SN74V245 are illustrated also. Creating waveform descriptors and development of programming Firmware are thoroughly researched.
