The term quad buffering is the use of double buffering for each of the left and right eye images in stereoscopic implementations, thus four buffers total (if triple buffering was used then there would be six buffers). The command to swap or copy the buffer typically applies to both pairs at once, so at no time does one eye see an older image ...
Without an IOMMU, the operating system would have to implement time-consuming bounce buffers (also known as double buffers [3]). Memory is protected from malicious devices that are attempting DMA attacks and faulty devices that are attempting errant memory transfers because a device cannot read or write to memory that has not been explicitly ...
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
Double buffering Using a dedicated buffer for rendering and copying the result to the screen buffer when finished. This prevents stutter on the screen and the user seeing rendering in progress. Drawcall A single rendering command submitted to a rendering API, referring to a single set of render states.
Triple Buffering may result in a frame being discarded without being displayed if two or more newer frames are completely rendered in the time it takes for one frame to be sent to the display. By contrast, Direct3D swap chains are a strict first-in, first-out queue , so every frame that is drawn by the application will be displayed even if ...
By switching between main and shadow memory on alternate frames, double-buffered video could be used. Acorn provided a demonstration program in BASIC showing scrolling cloud animation with and without double buffering. The video game Firetrack would also use double buffering if shadow RAM was present.
The schema compiler runs on Android, Microsoft Windows, macOS, and Linux, [3] but games and other programs use FlatBuffers for serialization work on many other operating systems as well, including iOS, Amazon's Fire OS, and Windows Phone. [4] Van Oortmerssen originally developed FlatBuffers for game development and similar applications. [5] [1]
The operating system must manage the bank-switching operation to ensure that program execution can continue when part of memory is not accessible to the processor. Bank switching is a technique used in computer design to increase the amount of usable memory beyond the amount directly addressable by the processor [ 1 ] instructions.
