  • Patent number: 8441482
    Abstract: Aspects include systems, methods, and media for implementing methods relating to detection of invalid intersections during ray tracing. Invalid intersections can arise from imprecision in computer-based number representation, causing ray origins to be located inappropriately. In some aspects, a ray can be associated with information relating to an expected angle between the ray's direction and a normal for a to-be-identified primitive intersected by that ray. If the angle between the ray's direction and the normal of an intersected primitive is within expectations, then that information can be used in predicting whether the intersection is valid. Such expectation information can be presented as a single bit determined by a shader performing a dot product of the ray and a normal of a primitive intersected by a parent ray, or can be obtained as a by-product of ray/primitive intersection testing.

  • Patent number: 8441495
    Abstract: Systems and methods for determining a compression tag state prior to memory client arbitration may reduce the latency for memory accesses. A compression tag is associated with each portion of a surface stored in memory and indicates whether or not the data stored in each portion is compressed or not. A client uses the compression tags to construct memory access requests and the size of each request is based on whether or not the portion of the surface to be accessed is compressed or not. When multiple clients access the same surface the compression tag reads are interlocked with the pending memory access requests to ensure that the compression tags provided to each client are accurate. This mechanism allows for memory bandwidth optimizations including reordering memory access requests for efficient access.

  • Patent number: 8441524
    Abstract: A digital zoom rate of two-dimensional images zoomed by a digital zoom unit is obtained. When the obtained digital zoom rate is larger than 100%, at least one of the digitally zoomed two-dimensional images is modified based on an enlarged amount of parallax to provide an amount of parallax between the digitally zoomed two-dimensional images equal to the enlarged amount of parallax. The enlarged amount of parallax is obtained by enlarging, at a moderated digital zoom rate, an amount of parallax between the two-dimensional images before being digitally zoomed, and the moderated digital zoom rate is obtained by moderating the digital zoom rate at a moderation rate, where the moderation rate increases as the zoom rate increases. Then, a display unit is caused to carry out three-dimensional display based on the modified two-dimensional images.

  • Patent number: 8441525
    Abstract: A method for synchronizing a function on a remote device with a function on a primary device includes selectively broadcasting, from a radio frequency (RF) transmitter of the primary device, data broadcast on channels at different times relative to a fixed period strobe signal of the primary device. Only the channels that have a noise level below a specified threshold level selectively broadcast the data and each of the channels have an associated fixed time frame offset relative to the fixed period strobe signal. Each of the channels is broadcast after their associated fixed time frame offset expires. An RF receiver of the remote device receives the data on one of the channels. The data on each of the channels is received at different times, depending on its associated fixed time frame offset, which results in the data on each received channel having an associated received time reference relative to a strobe signal of the remote device.
