2.3.3 UART Subsystem

The Universal Asynchronous Receiver/Transmitter (UART) subsystem implements the fabric UART logic to interface with GUI, which is used as a user interface to control and display status of the running design. The UART subsystem has three
sub-modules:

  • UART RX Interface
  • UART TX Interface
  • CORE UART

The following figure shows the UART subsystem.
