摘要： A buffer, a method, and a computer program product for DMA transfers are provided that are designed to save memory space within a local memory of a processor. The buffer is a return buffer with a portion reserved for DMA lists. A DMA controller accomplishes DMA transfers by: reading address elements from a DMA list located in the DMA list portion; reading the corresponding data from system memory; and copying the corresponding data to the return buffer portion. This buffer saves space because when the buffer begins to fill up the corresponding return data can overwrite the data in the DMA list. Accordingly, the DMA list overlays on top of the return buffer, such that the return data can destruct the DMA list and the extra storage space for the DMA list is saved.

摘要： The present invention renders a triangular mesh for employment in graphical displays. The triangular mesh comprises triangle-shaped graphics primitives. The triangle-shaped graphics primitives represent a subdivided triangular shape. Each triangle-shaped graphics primitive shares defined vertices with adjoining triangle-shaped graphics primitives. These shared vertices are transmitted and employed for the rendering of the triangle-shaped graphics primitives.

摘要： An apparatus and method for efficient communication of producer/consumer buffer status are provided. With the apparatus and method, devices in a data processing system notify each other of updates to head and tail pointers of a shared buffer region when the devices perform operations on the shared buffer region using signal notification channels of the devices. Thus, when a producer device that produces data to the shared buffer region writes data to the shared buffer region, an update to the head pointer is written to a signal notification channel of a consumer device. When a consumer device reads data from the shared buffer region, the consumer device writes a tail pointer update to a signal notification channel of the producer device. In addition, channels may operate in a blocking mode so that the corresponding device is kept in a low power state until an update is received over the channel.

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 is provided to allow virtual devices that use a plurality of processors in a multiprocessor systems, such as the BE environment. Using this method, a synergistic processing unit (SPU) can either be dedicated to performing a particular function (i.e., audio, video, etc.) or a single SPU can be programmed to perform several functions on behalf of the other processors in the system. The application, preferably running in one of the primary (PU) processors, issues IOCTL commands through device drivers that correspond to SPUs. The kernel managing the primary processors responds by sending an appropriate message to the SPU that is performing the dedicated function. Using this method, an SPU can be virtualized for swapping multiple tasks or dedicated to performing a particular task.

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 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.
