Detection of Baudrate in UART Automatically By Using VHDL

Rosamma Antony, Manju M S

This paper concentrates on developing a serial communication protocol (UART) with automatic baud rate detection. Automatic baudrate detection is useful for establishing communication link between two devices.The slaves device will able to detect the baudrate of the master controller and adjust accordingly.UART universal asynchronous receiver transmitter is generally used for better transmission of serial data that is either transmit or receive data serially. It involves designing of basic modules using Very High Speed Integrated Circuit Hardware Description Language (VHDL).
