VHDL Implementation of Universal Asynchronous Transmitter

The paper highlights the detail design of UART’s transmitter module which has asynchronous Last In Last Out as buffer for achieving the better speed synchronization between the processor and the UART interface. The paper starts by describing the behavior of transmitter module of Universal Asynchronous Receiver Transmitter using VHDL. The complete design of transmitter block is functionally verified using ModelSim SE 13.1. In the results the simulation waveforms are described.
