Android View buffer mechanism and Android View BUFFER MECHANISMThe content displayed by the View component can be saved as bitmap through the cache mechanism. The main methods are as follows:VoidSetDrawingCacheEnabled (boolean flag ),BitmapGetDrawingCache (boolean autoScale ),VoidBuildDrawingCache (boolean autoScale ),VoidDestroyDrawingCache ()To obtain the cache, you must first enable the cache using the s

The more memory available for SQLSERVER, the more resources SQLSERVER has to use in the buffer zone, which can reduce the number of times the server reads data from the disk to obtain static information or compile the process plan. To adjust the memory occupied by SQLSERVER, you can set the totalmemory parameter in the server configuration file. The value of this parameter specifies the total memory required by SQLSERVER at startup. If the value is 10
Label:InnoDB maintains a cache of data and index information to the memory of the storage area called buffer pool, which caches the most recently accessed data. By configuring the parameters of each buffer pool, we can significantly improve the performance of MySQL. InnoDB buffer pool is based on the LRU algorithm, we can easily understand the following LRU algor

In many OpenGL operations, we send a large chunk of data to OpenGL, such as passing the vertex array data that needs to be processed. Transferring this data can be very simple, such as copying data from the system's memory to a graphics card. However, because OpenGL is designed according to the client-server model, the data must be transferred from client memory to the server at any time that OpenGL requires data. If the data is not modified, or if the client and server are on different computer
Absrtact: In the past decade, the type of buffer overflow is the most common form of security vulnerabilities. More seriously, buffer overflow vulnerabilities account for the vast majority of remote network attacks, which can give an anonymous Internet user access to some or all of the control of a host computer! If buffer overflow vulnerabilities are effectively

As you know, the data is read from the channel int
Objective JavaScript is designed for browsers to handle Unicode-encoded strings well, but not for binary or non-Unicode-encoded data. Node.js inherits the language features of JavaScript while expanding the JavaScript language, providing a buffer class for binary data processing, allowing Node.js to handle various types of data like other programming languages. There are many articles on the internet about buffe

The implementation of ring buffer Bufferc language The problem of too many Message Queuing lock calls is solved, and the other annoying thing is probably too much memory allocation and release operations. The frequent memory allocation not only increases the overhead of the system, but also makes the memory fragmentation increasing, which is very unfavorable to the long-term stable operation of our server. Perhaps we can use memory pools, such as the

the principle of Buffer cacheOne1) When a server process needs to read the data into the buffer cache, it must first determine whether the data exists in buffer , if it exists and is available, to get the data, and to move it on the LRU list based on the LRU algorithm . Block; If the data does not exist in the buffer,

Serial Ring Buffer experiment Introduction to 1.1 experiment The simplest method of serial port data processing is that the data is received and sent back in the same mechanism: successfully received a number, triggered into an interrupt, read the data in the interrupt function, and then immediately. This kind of data processing mechanism is "non-buffered interrupt mode", although this data processing method does not consume time, but this kind of
Objective In Node.js, a buffer class is defined, which is used to create a buffer that stores binary data specifically.

First, overview: The serial port usually contains two buffers, that is, the send buffer and receive buffer. When sending data, the data is sent to a buffer and then sent via a serial port, and the received data is received before being read. Reasonable and appropriate use of buffer, not only can make the normal commun
