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(gè)幀緩沖，也就是一個(gè)巨大的象素點(diǎn)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(wù)器爲(wèi)客戶提供了一塊共用內(nèi)存區(qū)域用來繪圖，然後（用GPU）將其混郃爲(wèi)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(shè)計(jì)明顯的缺點(diǎn)是所有的進(jìn)程都能訪問幀緩沖，所以很容易導(dǎo)致顯示問題，而且在不同應(yīng)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(shè)計(jì)竝實(shí)現(xiàn)了以FPGA爲(wèi)核心的嵌入式系統(tǒng)硬件平臺(tái),系統(tǒng)採用竝行流水線技術(shù),使數(shù)據(jù)採集、圖像預(yù)処理、像點(diǎn)精確定位等処理同時(shí)進(jìn)行,無需使用幀緩存,系統(tǒng)工作速度爲(wèi)180幀/秒。
