摘要： The desire to use an Accelerated Processing Device (APD) for general computation has increased due to the APD's exemplary performance characteristics. However, current systems incur high overhead when dispatching work to the APD because a process cannot be efficiently identified or preempted. The occupying of the APD by a rogue process for arbitrary amounts of time can prevent the effective utilization of the available system capacity and can reduce the processing progress of the system. Embodiments described herein can overcome this deficiency by enabling the system software to pre-empt a process executing on the APD for any reason. The APD provides an interface for initiating such a pre-emption. This interface exposes an urgency of the request which determines whether the process being preempted is allowed a grace period to complete its issued work before being forced off the hardware.
摘要翻译：由于APD的示范性能特征，使用加速处理装置（APD）进行通用计算的愿望增加。然而，由于无法有效地识别或抢占过程，目前的系统在向APD发送作业时会产生高额的开销。通过流氓流程占用任意时间的APD可以防止有效利用现有的系统容量，并可以减少系统的处理进度。本文描述的实施例可以通过使得系统软件由于任何原因预先在APD上执行的过程来克服这个缺陷。 APD提供了一个用于启动此优先级的接口。该接口暴露了该请求的紧急性，该请求确定被抢占的进程是否被允许在宽限期之前完成其发出的工作，然后才被强制关闭硬件。

摘要： A method and apparatus for accelerating animation in a video graphics system is accomplished by storing drawing operations for a first scene in a bus master buffer. The first scene is to be drawn to a first frame. A frame flip operation is then stored in the bus master buffer at a location subsequent to the drawing operations for the first scene such that when accessed by a graphics processor, the frame flip will be performed after the drawing operations for the first scene have completed. Drawing calculations for a second scene to be drawn to a second frame are performed, and the resulting drawing operations are stored in the bus master buffer at a location subsequent to the page flip operation. The graphics processor is signaled, and the graphics processor fetches and executes the commands in the bus master buffer sequentially such that the drawing operations to the first frame are performed first, followed by the frame flip operation and finally the drawing operations to the second frame.

摘要： This invention is concerned with display apparatus of the Head-Up-Display (H.U.D.) type which finds utility in e.g. fighter aircraft. The invention is concerned with providing an H.U.D. which has a profile depth which is substantially and preferably much less than the diameter of the exit lens. The arrangements of the H.U.D. include a cathode ray tube (C.R.T.) display source, a collimating optical means having a plurality of lenses with at least an entrance lens and an exit lens together with a prism and combining means for combining displayed visual information with the view of the scene or object. The prism is so arranged in relationship to the display source that internal reflection of light from the display source within the prism and transmission of light towards the combining means is such as to enable the modular unit profile depth to be between 40% and 60% less than the exit lens diameter. Embodiments are shown which incorporate compensating means to compensate for CRT mechanical axis tilt at an angle with respect to e.g. the aircraft horizontal.

摘要： An "eye-piece" system for an infra-red afocal telescope comprises a positive back element having a concave or convex back surface and a convex front surface, and a pair of elements closely spaced to define a gas lens therebetween, the back element of the pair having a convex back surface and the front element of the pair having a concave front surface, the pair of elements in combination with the gas lens therebetween being of positive power. The "eye-piece" system can be used in combination with an objective lens system to provide a collimated magnified view of a scene or object, from which infra-red radiation is received, at a real exit pupil where a scanner operates, and can provide a wide field of view of around 70 degrees or more in the scanner space.
