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。
An optical disc data transmission control system is introduced. The system is independent of the computer work, you can easily and flexibly form a variety of data transmission control system to avoid the intervention of the host computer system, greatly reducing the complexity of the control system to avoid the bus on the number of connected devices limit. The use of 16-speed DVD ROM, the application of PIOMode4 protocol, in theory, the system can achieve the highest burst transmission speed of 16 6Mbit / s. System central processor using SCM system, through internal programming, can be adapted to different occasions. The output port uses a data buffer to ensure continuous data output at high speed.
