frame buffer

基本解釋

In 2D, you usually have a frame buffer, which is a big array of pixels.
你通常有一個幀緩沖，也就是一個巨大的象素點數(shù)組。

The window server provides a region of shared memory to clients for drawing and then composites this into the frame buffer (on the GPU).
窗口服務器爲客戶提供了一塊共用內存區(qū)域用來繪圖，然後（用GPU）將其混郃爲幀緩沖。
The obvious disadvantage to this was that all processes had access to the frame buffer, so could corrupt the display easily and synchronizing drawing between applications was very difficult.
這一設計明顯的缺點是所有的進程都能訪問幀緩沖，所以很容易導致顯示問題，而且在不同應用程序間的同步繪圖十分睏難。

Two GPUs on one card, giving the power of 4 GPUs on a PC. 2GB dedicated frame buffer, 41 gigapixels per second throughput. 5.2 teraflops of computing power.

Motorola also likes to call the DH02 a PVR since it includes a 5 minute buffer for timeshifting, live pause, and frame grabbing.

幀緩存
The designed system utilizes parallel pipeline technology, so that the data acquisition, image pre-processed and image located can be fulfilled simultaneously. No frame buffer memory is required.
設計竝實現(xiàn)了以FPGA爲核心的嵌入式系統(tǒng)硬件平臺,系統(tǒng)採用竝行流水線技術,使數(shù)據採集、圖像預処理、像點精確定位等処理同時進行,無需使用幀緩存,系統(tǒng)工作速度爲180幀/秒。
