高速数据传输控制系统的设计

Design of the high speed optical disk data transfer control system

介绍了一种光盘数据高速传输控制系统。该系统相对计算机独立工作,可以方便灵活地组成各种数据传输控制系统,避免了计算机主机系统的介入,大大缩小了控制系统的复杂程度,避免了总线对连接设备个数的限制。使用16倍速DVD ROM,应用PIOMode4协议,在理论上该系统可以达到16 6Mbit/s的最高猝发传输速度。系统中央处理器采用单片机系统,通过内部编程,可以适应于不同的使用场合。输出端口使用数据缓冲器,以保证数据高速连续输出。

A novel high speed, optical disk data transfer control system is presented. This system can work independently to the host processor and can avoid the interference of the host processor. The complexity of the whole system is decreased. Using 16×DVDROM, PIO Mode 4 protocol, 16.6Mbit/s data transfer rate is realized. The micro chip unit (MCU) is used as the central controller , it suits many kinds of workload environment without modifying the system hardware. The buffer can keep the continuous output data.
