Latest Patents

Among his latest patents is the "Broadcast aperture remapping for multiple graphics adapters." This invention provides a system and method for remapping and redirecting accesses to a memory space shared between graphics devices. It allows a single device driver to interface between an application program and multiple graphics devices. Each graphics device supplies configuration information to the BIOS, particularly regarding memory space requirements for prefetchable and non-prefetchable memory spaces. The allocation of memory space for the graphics devices is determined based on this configuration information. A switch device, which interfaces between a host processor and each graphics device, is programmed to redirect accesses to a portion of the allocated memory space to only one of the graphics devices. Accesses to another portion of the allocated memory space may be remapped to all of the graphics devices or a subset of them.

Another notable patent is the "Frame buffer region redirection for multiple graphics adapters." This invention represents multiple prefetchable memory resources, such as frame buffers connected to graphics devices, as a unified prefetchable memory space for access by software applications. A graphics surface can be processed by multiple graphics devices, with portions of the surface residing in separate frame buffers, each linked to one of the multiple graphics devices. One or more redirection regions can be specified within the unified prefetchable memory space. Accesses within a redirection region are transmitted to a prefetchable memory of a single graphics device, while accesses within the unified prefetchable memory space, but outside of any redirection region, may be broadcast to all of the prefetchable memories of the multiple graphics devices.
