PipelineThe pipeline operator "|" provided by Linux is used to separate the two commands. The output of the command on the left of the pipeline operator is used as the input of the command on the right of the pipeline operator. The continuous use of pipelines means that the output of the first command will be used as the input of the second co
What is rendering)
A simple understanding of rendering may be like this: it is to convert the description of a 3D object or a 3D scene into a two-dimensional image, and the generated two-dimensional image can well reflect a 3D object or a 3D scene (1):
What is a rendering pipeline?
A rendering pipeline, also known as a rendering pipeline, is a parallel p
Resolution: (1) formula for throughput: Number of commands divided by the time of the pipeline (2) formula for calculating the time of the pipeline: time required for a command + (number of command lines-1) * The longest instruction period7 + (8-1) * 3Assembly line:A pipeline is a quasi-parallel processing technology that allows multiple commands to overlap durin
A pipe is the earliest form of communication between Unix processes. It exists in all UNIX implementations. You need to know the following about pipelines:
1. It is half-duplex, that is, data can only flow in one direction. Although pipelines can be full-duplex in Some UNIX implementations, some system settings are required. In Linux, it is half-duplex.
2. It has no name, so it can only be used between processes with common ancestor. It is usually used between parent and child processes. Althoug

The OpenGL rendering pipeline works as follows:
1. Prepare and render vertex array data
2. vertex processing:
1. Each vertex must be processed by the vertex coloring tool. Each vertex is processed as an output vertex in sequence in the data stream;
2. Optional fragment stages of element and surface;
3. optional element geometric coloring machine processing, ou

Famous pipe nameless pipe and famous pipe:1. Pipeline is a special type of file, in the first-in- first-out to meet the principle of write can read and write, cannot locate read-write location.2. The piping is unidirectional.3. The nameless pipe is blocked in the read-write location , and the famous pipe is blocked at the creation location .4. nameless pipes are generally used only for inter- relationship interprocess communication; A well- known

Anonymous pipelineA pipeline is a one-way channel, a bit like a shared-memory cache. The pipe has both ends, including inputs and outputs. For a process, it sees only one end of the pipe, either the input or the output.Os.pipe () returns 2 file descriptors (R, W), which represent both readable and writable. The sample code is as follows:#!/usr/bin/pythonImportTimeImportOs def child(wpipe):Print' Hello from child ', Os.getpid ()) while True: Msg =' How
Communication effects between processes1. Data transfer: A process needs to upload his data to other processes2. Resource Sharing3. Process notification Events4, Process Control: Some processes completely control the execution of another process, such as debug State AHWe need to take full control of his every step of the operation;Communication development HistoryThe communication IPC between Linux processes evolved from the following sections:1. Communication between UNIX processes2. Communicat
The previous section learned the Nameless pipe, which learns named Pipes.Two Named pipesNameless pipes can only be used to communicate between a parent-child process or sibling process, which brings trouble to the exchange of data between unrelated processes, and solving this problem is another pipeline communication for this SectionTo learning: Named pipes.A named pipe is also known as a FIFO file, and the FIFO differs from the

Pipe Introduction:
Pipelines are a way of communicating between processes, which is equivalent to having a tunnel between two processes that can pass the message through the tunnel; The pipe is located outside the address space of the process, and the pipe is divided into anonymous pipes and named pipes two kinds;anonymous pipes are created by pipe, and named Pipes are cr

Describes how the xNa game studio content pipeline lets you build art assets into your game automatically from the file formats in which they are maintained.
Use content pipeline to convert art assets from file to resources that can be maintained by the game.
Most games use art in the formModels,Meshes,Sprites,Textures,Effect
device is connected to the USB bus. In order to distinguish each device, the USB Bus assigns a serial number to each device. Then, to achieve multiple communications, the device provides multiple endpoints, it is also necessary to compile the number, so that the host will eventually contact the endpoint.
There are four channels in the USB world, which correspond to four transmission modes in the USB world: control Transmission corresponding control pipelin
Sometimes during the process of developing a program, there is data interaction between the two processes. The signaling mechanism enables process communication. It works through an "interrupt-response" asynchronous Pattern. But as far as communication is concerned, the signal is still not enough. Because it is not able to carry any other information. Using only the signaling mechanism to achieve process communication is stretched, and the advantages of the signal are not. Therefore, new methods
Pipeline command (pipe)As we said earlier, the output data will appear when the bash command executes! So if this group of data must go through a few formalities to get the format we want, how should we set it? This involves a problem with the pipeline command (pipe), and the pipeline command uses the "| "This defining symbol!" In addition, the
