The noise generator is used as a basic USB device, USES the control transfer and interrupt transfer.
本课题设计的噪声发生器作为基础usb设备，采用了控制传输和中断传输。
USB protocol has four transfer types: Control transfer, Bulk transfer, Interrupt transfer, and Isochronous transfer.
该协议具有四种传输方式，即控制传输、批量传输、终端传输和等时传输。
Control transfer, interrupt transfer and bulk transfer are used to realize the transfer of different type of data and command.
采用控制、中断和批量三种方式来实现不同类型数据或命令的传输。
Flexible setting of interrupt and DMA is adopted in the software design, which improves the efficiency of data transfer and performance of DSP.
在软件设计中，通过灵活设置中断与DMA，不仅提高了图像数据的传输效率，而且充分发挥了DSP的高速性能。
Realize the interface between PCI9054 and the PCI bus, including the bus arbitration, read and write of the registers, the configuration of the EEPROM, the DMA transfer, interrupt response and so on.
