Hardware abstraction layer

Definitions

A software layer that provides a uniform interface to hardware, allowing operating systems and applications to interact with physical components without needing to know their specific implementation details.

A set of routines that emulates specific hardware, enabling software to run on different platforms by masking the differences between underlying physical devices.

Examples

The hardware abstraction layer allows the operating system to communicate with various types of physical components without needing specific drivers for each one.

By implementing a robust hardware abstraction layer, developers can ensure that their software remains portable across different hardware architectures.

The performance of the system can sometimes be impacted by the overhead introduced by the hardware abstraction layer.

Synonyms

HAL Abstraction layer Hardware abstraction Device abstraction layer Hardware interface layer Hardware adaptation layer Hardware abstraction interface
