Abstract
Official abstract text for this publication.
Extended features such as registers and functions within processors are made available to operating systems (OS) using an extended-state driver and by modifying instruction set extensions, such as XSAVE. A map-table designates a correspondence between memory locations for storing data relating to extended features not supported by the OS and called by an application. As a result, applications may utilize processor resources which are unsupported by the OS.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a processor; a memory; a driver module stored in the memory to: receive a call for an application to use an extended feature available on the processor; register a thread of the application in a map-table stored in a first location in the memory; assign an extended feature image location in the memory to the thread for holding a state of the extended feature when not in use; return to the application a table location refer…
