Buffer fifo
A circular buffer first starts out empty and has a set length. In the diagram below is a 7-element buffer: Assume that 1 is written in the center of a circular buffer (the exact starting location is not important in a circular buffer): Then assume that two more elements are added to the circular buffer — 2 & … WebMar 31, 2024 · FIFO Buffer In our previous tutorial, our UART interface could only send and receive one byte at a time. To solve that problem, let’s implement a First In First Out (FIFO) buffer to hold the previous two values in data registers. We define some specifications for our FIFO buffer below. 16-bit data bus Duplex read/write Read and write enable
