MXOS HAL-I APIs

 

MXOS’s hardware abstraction layer is the interface layer between the operating system kernel and the hardware circuitry.

The purpose is to abstract the hardware.It hides the hardware interface details of a specific platform,

provides a virtual hardware platform for the operating system, makes it hardware-independent, and can be ported on multiple platforms.

 

It is a programming layer that allows a computer operating system to interact with hardware devices at the logical layer rather than the hardware layer.

The hardware abstraction layer can be invoked by either the operating system core or the hardware driver.

In either case, the calling program does not need to know the specific design details of the hardware, just the parameters required by the abstraction layer.
