System Verilog implementation of duplex Universal Asynchronous Receiver Transmitter (UART) for 7 bit data packet
UART stands for Universal Asynchronous Receiver Transmitter . It is widely used as a hardware communication protocol since it does not require the clocks to be in sync with each other (hence asynchronous) . Duplex system means that the device can transmit and receive data at the same time .
UART transmitter converts multi bit data into single bit data to transmit it , whereas UART Receiver takes the incoming single bit data and reassembles it into packet . In my implementation of UART module , the UART Transmitter starts transmitting when posedge is given to the start pin . The UART receiver starts receiving when the first incoming bit is 1 (high) .
