US Patent:

20120188258, Jul 26, 2012

Filed:

Nov 4, 2011

Appl. No.:

13/289304

Inventors:

Rex MCCRARY - Oviedo FL, US
Michael Houston - Cupertino CA, US
Philip J. Rogers - Pepperell MA, US
Gongxian Jeffrey Cheng - Toronto, CA
Mark Hummel - Franklin MA, US
Paul Blinzer - Bellevue WA, US

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

G06F 15/16

US Classification:

345502

Abstract:

A method, system, and computer program product are disclosed for providing improved access to accelerated processing device compute resources to user mode applications. The functionality disclosed allows user mode applications to provide commands to an accelerated processing device without the need for kernel mode transitions in order to access a unified ring buffer. Instead, applications are each provided with their own buffers, which the accelerated processing device hardware can access to process commands. With full operating system support, user mode applications are able to utilize the accelerated processing device in much the same way as a CPU.
