Hardware Abstraction Layer

Definition

A hardware abstraction layer (HAL) is a programming interface that allows software to interact with hardware components without needing to understand the specifics of the hardware. By providing a consistent interface, HAL facilitates portability and reduces complexity in developing applications that can run on different hardware systems, which is particularly important in the realm of quantum computing and simulators.
