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。

Only the kernel can directly communicate with an SPU and therefore needs to abstract the hardware interface into system calls or device drivers.

瘦内核(或微内核)方法使用了第二个内核作为硬件与Linux内核间的抽象接口(见图3)。

The thin-kernel (or micro-kernel) approach USES a second kernel as an abstraction interface between the hardware and the Linux kernel (see Figure 3).

硬件抽象层利用底层微内核提供的API对底层硬件和外设进行访问和控制，提供一个抽象硬件平台和统一的硬件接口。

We provided an abstract hardware platform and a unified hardware interface by the use of the underlying microkernel APIs for the underlying hardware and peripherals to access and control.

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。

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