hardware abstraction layer การใช้

• MS-DOS is a disk operating system, not a hardware abstraction layer.
• To ease the use of software-incompatible devices, manufacturers often provide hardware abstraction layers.
• This interface is normally done by a Device Driver or Hardware Abstraction Layer.
• One of the earlier adopters was the ( nowadays deprecated ) Hardware Abstraction Layer.
• Additionally, PicOS has a hardware abstraction layer that lets it run atop networking ASICs of various makers.
• Other architectures based on Hardware Abstraction Layer or exokernels could move the drivers out of the microkernel.
• The gralloc hardware abstraction layer ( HAL ) is used to allocate the buffers that underly " surfaces ".
• Eventually hardware abstraction layers ( HAL ) such as DirectX were developed which separate application software from the underlying hardware.
• WarpUP forms a hardware abstraction layer between the hardware and software, and ensures that the applications function correctly on PowerPC architecture.
• Primarily, a new layer known as HAL ( Hardware Abstraction layer ) was introduced to interconnect functions easily without altering C code or recompiling.
• On these systems the idle thread will call routines in the Hardware Abstraction Layer to reduce CPU clock speed or to implement other power-saving mechanisms.
• The virtualization solutions being sold under the product names CHARON-PDP, CHARON-AXP, CHARON-VAX, CHARON-HPA and CHARON-SSP consist of a combination of virtual machine and hardware abstraction layer.
• Due to the way Windows is tied to the hardware abstraction layer, you can't install to a PC and swap the drive to a completely different model.
• Windows Vista and later ( Windows Server 2008 and later for servers ) automatically detect which hardware abstraction layer ( HAL ) should be used at boot time.
• The kernel sits between the Hardware Abstraction Layer and the Executive to provide " multiprocessor synchronization ", thread and interrupt scheduling and dispatching, and trap handling and exception dispatching.
• The hardware abstraction layer represents the lowermost layer and isolates the operating system from the underlying hardware to make it easy to port the operating system to other platforms.
• The OpenGL virtual instruction set and virtual assembly language ARB assembly language and CUDA are examples of such hardware abstraction layers on top of the specialised processor native instruction set.
• Amiga Virtual Machines create a series of Hardware Abstraction Layers between the hosting machine hardware, and the software, and let it run as if it was in the original Amiga environment.
• Some confusion is caused by the fact that there exists a version called LNO ( an acronym for Linux Native Oberon ), which uses Linux as hardware abstraction layer ( HAL ).
• RTAI consists mainly of two parts : an Adeos-based patch to the Linux kernel which introduces a hardware abstraction layer, and a broad variety of services which make lives of real-time programmers easier.
