jelly io

Google has released the source code for Android 4.1 Jelly Bean. I put down the source code for the first time (for a whole night ), today, I spent the first morning compiling the ROM and flushing it to my Galaxy Nexus. Although Android 4.1 has been used for more than a week, as an Android developer and enthusiast, the entire process of downloading, compiling, and refreshing source code is quite meaningful. However, some problems have also been encount

The tutorial teaches you to use Photoshop to make crystal clear jelly text effect, mainly involves the knowledge point is to set the layer style, we can follow do, very simple, I believe you can learn. Tutorial Effect Chart: 1. New size self-setting 2. Make the background arbitrary I here is the drop, new layer, gradient below. 3. Add a background style as follows. 4. Text, the font used here is "Black Rose", can be downloade

Last week's Google version of Galaxy S4 (gt-i9505) 's Android 4.3 Jelly bean Brush pack Outflow, also gives us a preliminary understanding of some of the new Android 4.3 features. So what exactly did Android 4.3 update? Here are the new Android 4.3 features we've found. Camera Technically, the camera application UI changes little, a little change is mainly reflected in the settings bar, from the previous round of the column into a semicircle set b

The new system retains the original jelly Bean name, the overall user experience is not much change, but some new features are worthy of attention. Google now update In the new Google Now, it can index your emails about air tickets, meals, hotels, parcels, tickets, etc., and remind you at the right time. But these features require user authorization, and if you're worried, these new features don't make any sense to you. Google now also adds to the d

How do I know I'm done with IO?first, the event-driven model introductionTypically, when we write a program that server processes a model, there are several models: (1) Each time a request is received, a new process is created to process the request;(2) Each time a request is received, a new thread is cre

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall
