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.
