驱动器

The principle of constant power drive is: PD converts the change of output light power of laser diode into the change of diode current, and the change of current is feed back to voltage-current converser which adjusts output current of driver to compensate the laser diode.

这样，当激光器的输出光功率衰减时，驱动器相应的增大输出电流；当激光器的输出光功率增强时，驱动器就相应减小输出电流。对许多激光器应用来说，最希望脉冲输出，因为脉冲输出只有极小的结发热。

Since the motherboard with the soft, hard disk, such as the use of DMA operations between the peripheral, DMA operation of the response process is as follows (AST386 in the floppy disk to DMA as an example): floppy disk drive made by DREQ2 signal to the DMA controller (82C206), and DMA controller to the CPU (80386) issued HRQ signal, CPU end the current bus cycle after HLDA response signal to the DMA controller, DMA controller issued a final response signal DMA to the floppy disk drive DACK2 allow its data into the system bus.

由于主板与软、硬盘等外设之间采用DMA操作，DMA操作的应答过程如下(以AST386中软盘DMA为例)：先由软盘驱动器发DREQ2信号给DMA控制器(82C206)，然后DMA控制器向CPU(80386)发HRQ信号，CPU结束当前总线周期后发响应信号HLDA给DMA控制器，最后DMA控制器发DMA响应信号DACK2给软盘驱动器允许其数据进入系统总线。
