摘要： A system and method for generating an image that includes ray traced pixel data and rasterized pixel data is presented. A synergistic processing unit (SPU) uses a rendering algorithm to generate ray traced data for objects that require high-quality image rendering. The ray traced data is fragmented, whereby each fragment includes a ray traced pixel depth value and a ray traced pixel color value. A rasterizer compares ray traced pixel depth values to corresponding rasterized pixel depth values, and overwrites ray traced pixel data with rasterized pixel data when the corresponding rasterized fragment is “closer” to a viewing point, which results in composite data. A display subsystem uses the resultant composite data to generate an image on a user's display.

摘要： An input device is disclosed, one embodiment of which provides position information to an information handling system (IHS). The position information includes both location information and spatial orientation information of the input device in real space. The input device includes a location sensor which determines the absolute location of the input device in x, y and z coordinates. The input device also includes a spatial orientation sensor that determines the spatial orientation of the input device in terms of yaw, pitch and roll. The input device further includes a processor that processes the location information and the spatial orientation information of the input device in real space to determine an image view from the perspective of the input device in virtual space. Movement of the input device in real space by a user causes a corresponding movement of an image view from the perspective of the input device in virtual space. The input device itself displays the image view, or alternatively, an IHS to which the input device couples displays the image view.

摘要： A system and method for compiling source code for multi-processor environments is presented. Source code is compiled which creates an object file whereby the object file includes multiple object code subtasks. Source code subtasks are compiled into object code subtasks using one of three approaches which are 1) a lowbrow approach, 2) a brute force approach, and 3) a program directive approach. Each object code subtask is formatted to run on a particular processor type with a particular architecture, such as a microprocessor-based architecture or a digital signal processor-based architecture. During runtime, each object code is loaded onto its corresponding processor type for execution.

摘要： A task queue manager manages the task queues corresponding to virtual devices. When a virtual device function is requested, the task queue manager determines whether an SPU is currently assigned to the virtual device task. If an SPU is already assigned, the request is queued in a task queue being read by the SPU. If an SPU has not been assigned, the task queue manager assigns one of the SPUs to the task queue. The queue manager assigns the task based upon which SPU is least busy as well as whether one of the SPUs recently performed the virtual device function. If an SPU recently performed the virtual device function, it is more likely that the code used to perform the function is still in the SPU's local memory and will not have to be retrieved from shared common memory using DMA operations.
摘要翻译：任务队列管理器管理与虚拟设备相对应的任务队列。当请求虚拟设备功能时，任务队列管理器确定SPU当前是否被分配给虚拟设备任务。如果已经分配了SPU，则该请求在SPU所读取的任务队列中排队。如果尚未分配SPU，则任务队列管理器将其中一个SPU分配给任务队列。队列管理器根据哪个SPU最不忙，以及一个SPU最近是否执行了虚拟设备功能来分配任务。如果SPU最近执行了虚拟设备功能，则用于执行该功能的代码更有可能仍在SPU的本地存储器中，并且不需要使用DMA操作从共享的公共存储器中检索。

摘要： A system and method for balancing computational load across a plurality of processors. Source code subtasks are compiled into byte code subtasks whereby the byte code subtasks are translated into processor-specific object code subtasks at runtime. The processor-type selection is based upon one of three approaches which are 1) a brute force approach, 2) higher-level approach, or 3) processor availability approach. Each object code subtask is loaded in a corresponding processor type for execution. In one embodiment, a compiler stores a pointer in a byte code file that references the location of a byte code subtask. In this embodiment, the byte code subtask is stored in a shared library and, at runtime, a runtime loader uses the pointer to identify the location of the byte code subtask in order to translate the byte code subtask.

摘要： A sampling module for adaptively sampling static data sets is provided. Two or more rays are cast onto a surface from a single point of origin. The ray or rays intersect the surface at various locations. The distance between the intersection points of each pair of adjacent rays is calculated. This distance is the current sample density. The current sample density is compared to the desired sample density. If the current sample density is not equal to the desired sample density then the sample density of the next casting of rays is adjusted accordingly.

摘要： A system and method for adaptive span computation when ray casting is presented. A processor uses start point fractional values during view screen segment computations that start a view screen segment's computations a particular distance away from a down point. This prevents an excessive sampling density during image generation without wasting processor resources. The processor identifies a start point fractional value for each view screen segment based upon each view screen segment's identifier, and computes a view screen segment start point for each view screen segment using the start point fractional value. View screen segment start points are “tiered” and are a particular distance away from the down point. This stops the view screen segments from converging to a point of severe over sampling while, at the same time, providing a pseudo-uniform sampling density.
摘要翻译：提出射线铸造时的自适应跨度计算的系统和方法。处理器在视图屏幕段计算期间使用起始点分数值，该计算开始视图屏幕段的计算距离下降点的特定距离。这防止了图像生成过程中的过度采样密度，而不会浪费处理器资源。处理器基于每个视图屏幕段的标识符来识别每个视图屏幕段的开始点分数值，并且使用起始点分数值来计算每个视图屏幕段的视图屏幕段开始点。查看屏幕段开始点是“分层”的，距离下降点是特定的距离。这样就可以阻止观看屏幕段收敛到严重过采样点，同时提供一个伪均匀的采样密度。

摘要： A system and method for a DMA controller with multi-dimensional line-walking functionality is presented. A processor includes an intelligent DMA controller, which loads a line description that corresponds to a shape or line. The intelligent DMA controller moves through a memory map and retrieves data based upon the line description that includes a major step and a minor step. In turn, the intelligent DMA controller retrieves data from the shared memory without assistance from its corresponding processor. In one embodiment, the intelligent DMA controller may analyze a line using the rate of change along its minor axes in conjunction with locations where the line intersects subspaces and store array spans of contiguous memory along the line's major axis.

摘要： A system and method for terrain rendering using a limited memory footprint is presented. A vertical ray intersects a terrain data map at an angle which includes a minor step size. Weighting factors are assigned to triangular data sampling values and quadrilateral data sampling values based upon a vertical ray's minor step size. As a vertical ray's minor step size increases, a triangular data sampling's weighting factor increases and a quadrilateral data sampling's weighting factor decreases. Weighted triangular data sampling values and weighted quadrilateral data sampling values are combined to generate a vertical ray image point value.
