Universal Asynchronous Receiver/transmitter - Structure

Structure

A UART usually contains the following components:

  • a clock generator, usually a multiple of the bit rate to allow sampling in the middle of a bit period.
  • input and output shift registers
  • transmit/receive control
  • read/write control logic
  • transmit/receive buffers (optional)
  • parallel data bus buffer (optional)
  • First-in, first-out (FIFO) buffer memory (optional)

Famous quotes containing the word structure:

    ... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.
    Robert Musil (1880–1942)

    Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
    Senta: And a structure that will last for all time.
    Vashtar: Only history will tell that.
    Senta: Sire, will he not be remembered?
    Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.
    William Faulkner (1897–1962)

    The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?”
    Jean Baker Miller (20th century)
