Nvidia Corporation is an American worldwide technology company based in Santa Clara, California. Nvidia manufactures graphics processing units , as well as system-on-a-chip units for the mobile computing market. Nvidia's primary GPU product line, labeled "GeForce", is in direct competition with AMD's "Radeon" products. Nvidia also joined the gaming industry with its handheld Shield Portable and Shield Tablet, as well as the tablet market with the Tegra Note 7.In addition to GPU manufacturing, Nvidia provides parallel processing capabilities to researchers and scientists that allow them to efficiently run high-performance applications. They are deployed in supercomputing sites around the world. More recently, Nvidia has moved into the mobile computing market, where it produces Tegra mobile processors for smartphones and tablets, as well as vehicle navigation and entertainment systems. In addition to Advanced Micro Devices, its competitors include Intel and Qualcomm. Wikipedia.

A system, method, and computer program product are provided fir shading using a dynamic object-space grid. An object defined by triangle primitives in a three-dimensional (3D) space that is specific to the object is received and an object-space shading grid is defined for a first triangle primitive of the triangle primitives based on coordinates of the first triangle primitive in the 3D space. A shader program is executed by a processing pipeline to compute a shaded value at a point on the object-space shading grid for the first triangle primitive.

A system, method, and computer program product are provided for performing object-space shading. A primitive defined by vertices in three-dimensional (3D) space that is specific to an object defined by at least the primitive is received and a shading sample rate is computed for the primitive based on a screen-space derivative of coordinates of a pixel fragment transformed into the 3D space. A shader program is executed by a processing pipeline to compute shaded attributes for the primitive according to the computed shading sample rate.

A method, system, and computer program product for performing a lighting simulation are disclosed. The method includes the steps of receiving a three-dimensional (3D) model, receiving a set of probes, where each probe specifies a location within the 3D model and an orientation of the probe, and performing, via a processor, a lighting simulation based on the 3D model, the set of probes, and one or more light path expressions. The light path expressions are regular expressions that represent a series of events, each event representing an interaction of a ray at a location in the 3D model.

A magnetic power supply coupling system is disclosed. An integrated circuit module includes an integrated circuit die and a secondary winding that is configured to generate an induced, alternating current based on a magnetic flux. A primary winding is external to the integrated circuit module, proximate to the integrated circuit module, and coupled to a main power supply corresponding to an alternating current that generates the magnetic flux. The induced, alternating current is converted into a direct current at a voltage level to supply power to the integrated circuit die.

A true random number generator, a method of generating a true random number and a system incorporating the generator or the method. In one embodiment, the generator includes: (1) a ring oscillator including inverting gates having power inputs and (2) a time-varying power supply coupled to the power inputs to provide power thereto and including power perturbation circuitry operable to perturb the power provided to at least one of the power inputs.
