| 摘 要： | 多路超高速语音系统中,高速DSPTMS320C6713与USB2.0控制器CY68013的硬件连接选用Slave FIFOs方式,异步读写.其C6713通过通用McBSP0口获得FIFO的空、半满和满等状态信息,通过EMIF接口的CE2空间对CY7C68013进行读写操作.USB2.0数据传输系统的软件则通过固件、驱动程序及应用程序实现.

| Abstract: | In multi-route ultrahigh-speed voice system, the hardware linkage between high-speed DSP TMS320C6713 and USB2.0 controller CY68013 adopted Slave FIFOs mode and asynchronism read-write. The C6713 acquired situation information such as vacancy, half-full and full through McBSP0, and carried out reading and writing for CY7C68013 through CE2 space of EMIF interface. The software of USB2.0 data transmission system was realized through firmware, drive and application program. |
