UART implementation on FPGA

UART (Universal Asynchronous Receiver/Transmitter) is a communication protocol widely used for transmitting and receiving serial data between two devices. An FPGA (Field-Programmable Gate Array) is a reprogrammable integrated circuit that can be configured to implement digital logic functions.

To implement UART on an FPGA using HDL (Hardware Description Language), a UART IP core can be used. This IP core is typically written in Verilog or VHDL and includes the necessary logic for generating and receiving serial data, as well as controlling the baud rate and other communication parameters.

The UART IP core can be integrated into a larger FPGA design using a top-level HDL module. This module connects the UART IP core to the FPGA's input and output pins and specifies how the UART data will be processed by the rest of the design.

Once the FPGA design is synthesized and programmed onto the FPGA, the UART interface can be used to transmit and receive serial data between the FPGA and other devices, such as microcontrollers or computers.
