Communication between processes in Linux Named Pipe (FIFO)Name the pipe (FIFO), which is the same as the normal pipe. It is used as an intermediate postman to implement communication between two processes.The named pipe (FIFO) has the following features:1. The Named Pipe (FIFO) exists as a special device file.2. Data c

Linux inter-process communication-famous pipelines (FIFO) and linuxfifoFamous pipe (FIFO) Named Pipes are also called FIFO files, which are special files. Since all linux objects can be regarded as files, the use of Named Pipes becomes very consistent with file operations. (1) create a named pipe You can use one of the following two functions to create named pipe

Two independent asynchronous serial I/O ports are provided for the UART unit of the high-efficiency FIFO serial port based on the implementation of b0x (clock frequency: 60 MHz) on the ARM7, each communication port can work in the interrupt or DMA mode. That is, UART can generate an internal interrupt request or DMA request to transmit data between the CPU and the serial I/O port. It supports a transmission rate of up to 115.2 kb/s. Each UART channel

FIFO data buffers:FIFO (first Input firstly Output) an FIFO data buffer, the first to enter the data first read from the FIFO buffer, compared with the RAM has no external read and write address lines, the use is relatively simple, but only sequentially write data, sequential readout data, It cannot be read or written to a specified address by the address line,

I. Limitations of anonymous pipeline PIPE The main limitations of MPs queue are as follows: Only unidirectional data streams are supported; It can only be used between unrelated processes; No name; The buffer of the MPs queue is limited (the MPs queue is in the memory and a page size is allocated to the buffer when the MPs queue is created ); The pipeline transmits a non-formatted byte stream, which requires that the reader and writer of the pipeline have to specify the data format i

This code is used to sort out the FIFO buffer from the 30-day self-made operating system p135. Well written, so record it (added a function named fifo8_free to query the remaining capacity, which is useful ).

A major restriction of an unnamed pipeline application is that it has no name, so it can only be used for Kinship-related inter-process communication. After proposed by a famous Pipeline (named pipe or FIFO, this restriction is overcome. FIFO is different from pipelines in that it provides a path name associated with it and exists in the file system as a FIFO fil

Linux inter-process communication (IPC) Programming Practice (2) FIFO naming Pipeline In the previous article, we explained how to use anonymous pipelines to transmit data between processes, and also saw a defect in this method, these processes are started by a common ancestor process, which makes it inconvenient for us to exchange data between unrelated processes. Here, we will introduce another communication method of processes, named pipe, to solve

Introduction: Pipelines are the oldest IPC method on Unix systems, and pipelines provide an elegant solution: given the two processes that run different programs, how can the output of one process in the shell be used as input to another process? Pipelines can be used to 相关（一个共同的祖先进程创建管道） pass data between processes. FIFO is a variant of the pipeline concept, and one important difference between them is the communication that

I. Some simple understandings: We know that the pipeline has no signs, so we can only communicate in the same process Group. it is not possible between processes produced by different ancestors !! Therefore, the FIFO mechanism can only be single-stream! The difference is that FIFO has a flag! Each FIFO has... i. some simple understandings: We know that pipelines

Overview of Named PipesNameless pipes, because there is no name, can only be used for inter-relationship interprocess communication (many other details. See the Nameless pipe). in order to overcome this shortcoming. A named pipe (FIFO) is proposed. Also known as pipeline, FIFO file. A named pipe (FIFO) differs from an unnamed pipe in that it provides a pathname a

Calculating the FIFO depth is a common problem in the design FIFO. Common sense tells us that when the read rate is slower than the write rate, the FIFO can be used as a buffer element or queue in the system. The size of the FIFO therefore basically implies the capacity of the required cache data, which depends on the
