A computer system comprising a processor and a memory for storing instructions, that when executed by the processor performs a copy protection method. The copy protection method comprises executing a software loop of a first software application in a first operating system. A first call is executed in the software loop to a code portion. A decrypted code portion of the first software application is executed in a second operating system in response to the first call. The code portion is decrypted in response to a successful validation of the first software application.

Content protection via online servers and code execution in a secure operating system

A system, method, and computer program product are provided for implementing anti-aliasing operations using a programmable sample pattern table. The method includes the steps of receiving an instruction that causes one or more values to be stored in one or more corresponding entries of the programmable sample pattern table and performing an anti-aliasing operation based on at least one value stored in the programmable sample pattern table. At least one value is selected from the programmable sample pattern table based on, at least in part, a location of one or more corresponding pixels.

A method for scheduling work for processing by a GPU is disclosed. The method includes accessing a work completion data structure and accessing a work tracking data structure. Dependency logic analysis is then performed using work completion data and work tracking data. Work items that have dependencies are then launched into the GPU by using a software work item launch interface.

System and method for runtime scheduling of GPU tasks

A system and method for enhanced multi-sample anti-aliasing. The method includes determining a sampling pattern corresponding to a pixel and adjusting the sampling pattern based on a visual effect (e.g., post-processing visual effect). The method further includes accessing a first plurality of samples based on the sampling pattern. The first plurality of samples may comprise a second plurality of samples within the pixel and a third plurality of pixels outside of the pixel. The method further includes performing anti-aliasing filtering of the pixel based on the first plurality of samples and the sampling pattern.

Methods for code protection are disclosed. A method includes using a security processing component to access an encrypted portion of an application program that is encrypted by an on-line server, after a license for use of the application program is authenticated by the on-line server. The security processing component is used to decrypt the encrypted portion of the application program using an encryption key that is stored in the security processing component. The decrypted portion of the application program is executed based on stored state data. Results are provided to the application program that is executing on a second processing component.
