Starting with Android3.0 (API level 11), the Android 2D rendering pipeline provides better support for hardware acceleration. all of the drawing operations performed by hardware acceleration are done using the GPU on the View object's canvas . Because enabling hardware acceleration increases the need for resources, such an application consumes more memory.Hardwar

The Android standard hardware driver is divided into two parts, one is the hardware driver running in the Linux kernel, and the other part is the hardware abstraction layer running in user space. Using this method, the system can be hardware-independent, but also protect the interests of some manufacturers. In Android

September School season has arrived, DIY computer as a student of the most cost-effective choice, the beginning of the school year will be driven by a small round of installed boom. Because the students themselves do not have a financial source, to buy a computer also need to spend their parents ' money, so many sensible children's shoes in DIY installed on the special focus on cost-effective, helpless store profiteers many, each year DIY installed by the pit of the students a lot. For small whi

If you want to search for new hardware, you really don't know what command to use. System PnP can automatically search for new hardware, so there is no need to manually refresh the search. If you want to see the changes in the device, you can use the command line to implement it. method One, using WMIC (WMI command line)Using WMIC requires administrator privileges, which are installed and configured the fi

· Definition In fact, this buffer zone is a storage area of malloc, but it is not as good as that of malloc, which is applied in the memory, and the buffer zone is in the GPU/AGP, and its write and read speed is faster. Generally, the hardware buffer is used as the vertex buffer, index buffer, and Pixel Buffer. · Use Hardware buffer management is the hardwarebuffermanager responsible for a

This article translated from: http://developer.android.com/guide/topics/graphics/hardware-accel.html Determines whether a view object is accelerated by hardware. Sometimes, especially for custom view objects, It is very helpful for applications to know whether the current view object is accelerated by hardware. This judgment is particularly useful if the applicat
