A hardware abstraction layer (HAL) is an abstraction layer, implemented in software, between the physical hardware of a computer and the software that runs on that computer. . Its function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardwa
HAL (Hardware Abstraction Layer or rather Hardware Annotation Library) is a software subsystem for UNIX-like operating systems providing hardware abstraction. HAL is now deprecated on most Linux distributions and on FreeBSD. Functionality is being merged into udev on Linux as of 2008–2010 and devd on FreeBSD.
This software collection closely aligns with what many chip manufacturers refer to as a HAL (Hardware Abstraction Layer). In TI's context, it's termed DAL (Device Abstraction Layer). Its role revolves around furnishing fundamental functionalities and an API that an operating system can conveniently adapt to.
The Hardware Abstraction Layer in the architecture of Windows NT. The Windows Hardware Abstraction Layer (HAL) is implemented in hal.dll. [1] The HAL implements a number of functions that are implemented in different ways by different hardware platforms, which in this context, refers mostly to the chipset.
XtratuM would be the first layer of software (the one closest to the hardware), which provides a solid basis for the rest of the system. XtratuM 1.0 was initially designed as a substitution of the RTLinux HAL (Hardware Abstraction Layer) to meet temporal and spatial partitioning requirements. The goal was to virtualize the essential hardware ...
Kernel mode in Windows NT has full access to the hardware and system resources of the computer. The Windows NT kernel is a hybrid kernel; the architecture comprises a simple kernel, hardware abstraction layer (HAL), drivers, and a range of services (collectively named Executive), which all exist in kernel mode.

An operating system abstraction layer (OSAL) provides an application programming interface (API) to an abstract operating system making it easier and quicker to develop code for multiple software or hardware platforms. It can make an application less dependent on any one specific operating system.
