Patents by Inventor Kirill A. Dmitriev

Kirill A. Dmitriev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10430915
    Abstract: One or more copy commands are scheduled for locating one or more pages of data in a local memory of a graphics processing unit (GPU) for more efficient access to the pages of data during rendering. A first processing unit that is coupled to a first GPU receives a notification that an access request count has reached a specified threshold. The first processing unit schedules a copy command to copy the first page of data to a first memory circuit of the first GPU from a second memory circuit of the second GPU. The copy command is included within a GPU command stream.

  • Patent number: 10402937
    Abstract: A method for rendering graphics frames allocates rendering work to multiple graphics processing units (GPUs) that are configured to allow access to pages of data stored in locally attached memory of a peer GPU. The method includes the steps of generating, by a first GPU coupled to a first memory circuit, one or more first memory access requests to render a first primitive for a first frame, where at least one of the first memory access requests targets a first page of data that physically resides within a second memory circuit coupled to a second GPU. The first GPU requests the first page of data through a first data link coupling the first GPU to the second GPU and a register circuit within the first GPU accumulates an access request count for the first page of data. The first GPU notifies a driver that the access request count has reached a specified threshold.

  • Patent number: 9177413
    Abstract: A system, method, and computer program product are provided for generating unique primitive identifiers. A specified scope and geometry for a scene is received. A primitive identifier is generated for each primitive of a particular type, where each of the primitive identifiers is unique within the specified scope, and where the primitives are generated as the geometry for the 3D graphics scene is processed by a graphics processing unit. Different types may include patches, triangles, and vertices. The specified scope may be one of a frame, region, pixel, or draw call.
