For example, an activity has a background, and then the layout has its own background, and the sub-view has its own background. Simply by removing the necessary background image, this can reduce the number of red overdraw areas and increase the percentage of the blue area.

Each frame is a stationary image, and a fast and continuous display of frames creates t

The fifth feature is multi-channel, each H-coded IP core FPGA (Altera Stratix V) platform enables the implementation of 12-way encoding performance support 480p@30fps per channel. Other features such as: Color space support 4:0:0/4:2:0/4:2:2/4:4:4 color depth support: 8bit/. 10bit/12bit/14bit, compression ratio span 1/10~1/1000, the

Question 1:What is the relationship between 60Hz and 60fps? There is no relationship. FPS represents the frequency at which the GPU renders the screen, and Hz indicates how often the display is refreshed. A static picture, you can say that the picture fps is 0 frames per second, but absolutely not say that the screen refresh rate is 0Hz, that is, the refresh rate does not change with the content of the image. The game is good browser, we talk about dropped frames, refers to GPU rendering screen

mobile hardware works, so we have to understand what VSYNCis.Before we explain the vsync, we need to know two related concepts: Refresh Rate: Represents the number of times a screen is refreshed in a second, depending on the hardware's fixed parameters, such as 60Hz. Frame rate: Represents the number of frames that the GPU draws operations within one second, such as 30fps,60fps. The GPU gets the graphics data to render, and the hard

What about the Samsung EXYNOS7 processor? The following will bring you news about the performance of the Samsung EXYNOS7 eight processor, Exynos 7 is Samsung's new eight-core processor, what about its performance? Let's get to know each other. Exynos 7 uses 20nm HKMG fabrication process, carrying Cortex-a53+cortex-a57 dual quad core big.LITTLE architecture. It is expected that it will have HMP heterogeneous computing architecture, that is, can do eight nuclear full full "true eight core.

To the photographic enthusiasts for detailed analysis to share the Canon 700D camera and Canon 7D camera performance comparison. Analytical sharing: Canon 700D is equipped with a newly designed 18-55mm is STM lens, and the built-in stepper motor is quieter and smoother when shooting video. It also supports the 1920x1080 30fps Full HD short film shoot, in the use of LV viewing mode, the hybrid focus system can be rapid and accurate autofocus,

, adding a double 100% optical viewfinder with a visual field rate of 100% and a magnification of 100%. Canon G16 is equipped with an equivalent distance of 28-140mm 5 times Optical zoom lens, the most recent focus distance (mirror front) wide-angle 1cm, telephoto end of 40cm, with F1.8 large aperture, support 1920x1080 resolution 60FPS/30FPS Full HD video shooting, Provides a hand jitter compensation effect that increases the shutter

responsible for displaying different game states. It can be simply drawing on the canvas in the view, or saving a separate graphic buffer, and then passing it to the custom view or OpenGL view. The rendering standard is FPS, that is, how many frames are displayed per second. If it is 30fps, 30 images are displayed per second. for mobile devices, 30 frames are enough. Of course, the higher the FPS, the smoother the animation. Imagine a person walking,
