read fifo

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

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

What is FIFO? (First input firstOutput, first-in-first-out queue) This is a traditional method of execution in order, the first entry command is completed first and then pulled back, followed by the execution of the second command. 1. What is

What is FIFO(First Input first Output, FIFO queue) This is a traditional sequential execution method in which the first entry instruction is completed and retired, followed by the second instruction.1. What is FIFO.FIFO is the initials of the

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?

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
