Design of UART Module Based on FPGA

To realize data communication between computer and FPGA-based image processing system,a simple Universal Asynchronous Receiver Transmitter(UART)is designed by FPGA.The main function of UART is to realize data conversion between data disposal module and RS 232 serial port,that is to say,parallel data trinsmitted by data disposal module is converted into serial data flow,then it is transmitted into computer,the serial data is converted into parallel data for the usage of data disposal module.For predigesting circuit design and reducing electrocircuit proportion,parity check module is not needed.
