You can toggle between software and hardware vertex processing at any time when using the Hal device, the only device type that supports both hardware and software vertex processing.

你可以在使用硬件抽象层设备的任意时间绑定软件和硬件顶点处理，该唯一设备同时支持硬件和软件顶点处理。

A typical character of our system is that the HAL includes the DOS kernel and device driving, because we used the DOS kernel as the hardware boot_loader.

这个移植的特点就是把DOS内核和底层硬件驱动合起来作为操作系统的硬件抽象层调用。

The software structure is made up of device driver, hardware abstract layer (HAL), visual machine (VM) and reading ZIF file.

其中软件体系结构包括：驱动程序、硬件抽象层、虚拟机、读取接口数据文件。
