Line 1: An '''Operating System Abstraction Layer''' ('''OSAL''') provides an [[application programming interface]] (API) to an [[Abstraction (computer science)\|abstract]] [[Real-Time Operating System\|real time operating system]] making it easier and quicker to develop code for multiple [[software]] or [[hardware]] ~~plaforms~~platforms. OSAL deals with presenting an abstraction of the common system functionality that is offered by any Operating system by the means of providing meaningful and easy to use Wrapper functions that in turn encapsulate the system functions offered by the OS to which the code needs porting. A well designed OSAL provides implementations of an API for several Real Time Operating Systems (such as [[vxWorks]], [[eCos]], [[RTLinux]], [[RTEMS]]). Implementations may also be provided for non Real Time Operating Systems, allowing the abstracted software to be developed and tested in a developer friendly desktop environment.
