Latest Patents

One of his latest patents is titled "Package level power gating." This invention discloses a die package through which power domains within the chip may be isolated by removing vias within the package substrate, rather than using traditional power gating methods. This approach allows for multiple substrate options to be configured without specific vias, eliminating the need to design power gating circuitry into the die. As a result, this frees up die area for more functional logic while retaining the same pinout for PCB designers, regardless of which power domains are gated.

Another notable patent is the "Reconfigurable high-performance texture pipeline with advanced filtering." This invention includes circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in a fast and efficient manner. One such texture circuit increases the number of bilerps for each pixel in a group of pixels, particularly when trilinear or anisotropic filtering is required. For trilinear filtering, texels in the first and second level of detail are retrieved for multiple pixels during a clock cycle. When anisotropic filtering is performed, multiple bilerps can be retrieved for each of a number of pixels during one clock cycle.
