The term double buffering is used for copying data between two buffers for direct memory access (DMA) transfers, not for enhancing performance, but to meet specific addressing requirements of a device (esp. 32-bit devices on systems with wider addressing provided via Physical Address Extension). [5]
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 ...
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 ...
SDL-RT is based on the ITU Specification and Description Language replacing the data language with C. [4] Latest version of SDL standard (SDL'2010) now includes the support of C data types and syntax making SDL-RT basic principle part of the official standard. TNSDL is a variant developed by Nokia for their internal use.
The SIPO block then divides the incoming clock down to the parallel rate. Implementations typically have two registers connected as a double buffer. One register is used to clock in the serial stream, and the other is used to hold the data for the slower, parallel side. Some types of SerDes include encoding/decoding blocks.
In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams. [1] There were early circular buffer implementations in hardware. [2] [3]
Fully buffered DIMM architecture introduces an advanced memory buffer (AMB) between the memory controller and the memory module. Unlike the parallel bus architecture of traditional DRAMs, an FB-DIMM has a serial interface between the memory controller and the AMB. This enables an increase to the width of the memory without increasing the pin ...
It does not preclude the use of double-buffering. [3] Immediate mode is an alternative approach. Historically, retained mode has been the dominant style in GUI libraries; [4] however, both can coexist in the same library and are not necessarily exclusionary in practice. [5]
