Only the kernel can directly communicate with an SPU and therefore needs to abstract the hardware interface into system calls or device drivers.
只有内核才可以直接与SPU进行通信，因此需要将硬件接口抽象为系统调用或设备驱动程序。
Abstract Data acquisition and display system is the use of a device, collect data from outside the system and input to the internal system of an interface.
摘要：数据采集与显示系统是利用一种装置，从系统外部采集数据并输入到系统内部的一个接口。
The device Abstract Layer provides a set of standard communication interface functions unrelated with specific device, which is mapped to device drivers by file table, device table and driver table.
设备抽象层为上层应用程序提供了一套标准的、与设备无关的通信接口，并且通过文件描述表、设备描述表和驱动描述表建立了从通信接口到设备驱动的映射。
