Title: Systems, apparatuses, and methods for reducing the number of short integer multiplications
Inventor: ALBREKHT LLYA
IPC: G06F9/302
Filed: 2014-03-11
Abstract: The disclosed method relates to a square-multiply (SQRMUL) instruction, which involves calculating respective squares of first and second operands, and the multiplication of the first and second operands together, using a single multiplication instruction. A temporary variable is generated by left shifting a first operand by 2N, and OR-ing the shifted value with the second operand; with the temporary variable then squared - where N is log2 of the base of the data value. The value of the square of the first operand is obtained by right shifting the squared temporary variable by 4N. The square of the second variable is obtained by ANDing the squared temporary variable with ((1left shifted by N) -1). The multiplication of the first and second operands is obtained by ANDing the squared temporary variable with ((2 left shifted by 2N) -1), and by then right shifting by (2N +1). The destination operand may be a general purpose register or a packed data register, with each calculation stored in a different data element.

Inventor: OTSUKA HIROSHI
IPC: G06F11/34
Filed: 2014-03-25
Abstract: Disclosed is a method of calculating the probability that component in a computer system will fail in the future. The method starts by calculating a statistic for each of a set of components, among the components and other such items on a computer, according to first and second frequencies. When an occurrence of a failure of a certain type is predicted according to a first pattern, which is a combination of messages output from the components within a set period, a result is generated according to the statistic. The statistic relating to the probability the a component will fail. The result indicating a component in which the failure of a certain type is predicted to occur with a probability that is higher than a probability with which the failure of the same type is predicted to occur in any other component. The first frequency indicates how many times a message is output by a component before the component fails. The second frequency indicates how many times a message has been output within the set period.

Title: Systems and methods for soft shadowing in 3-D rendering
Inventor: Justin DeCell
IPC: G06T15/60
Filed: 2016-03-03
Abstract: Graphics processing where positions of primitives in a scene are represented by nodes of a hierarchical acceleration structure (or geometric acceleration data structure), comprising using the acceleration structure to identify visible surfaces of the scene, casting rays 820 from the visible surfaces 814 towards a light source 812 and determining whether these shadow rays are occluded or obscured. For a ray that is not occluded, identify a nearest-hit primitive 816 (the primitive that comes closest to causing an occlusion) by using the hierarchical acceleration structure 822 and computing the distance-ratio of hierarchical nodes that were hit by the ray as the ratio of a dimension (or a length) of the node d_1 to the distance along the ray to the hit d_2. The node with the smallest distance-ratio represent the nearest-hit primitive. An extent of occlusion is determined using data (such as the dimension of the node, distance along the ray or distance-ratio) related to the smallest distance-ratio node. The distance-ratio corresponds to an angle between the ray and the path to the nearest occlusion and this may determine the extent of occlusion. The extent of occlusion may be used to render shadow pixels. Soft shadows and penumbra regions can be created using simple ray tracing models.

The inven­tion also relates to a corresponding control device for an exhaust gas aftertreatment system (3) of an internal combustion engine (1) designed for lean-mixture operation. The ageing parameter may be determined on the basis of oxygen absorption of the NOx storage catalyst or air ratio downstream of the catalyst. The function measurement may be carried out in time relationship with a regeneration phase.
