Multi-channel UART Controller with Programmable Modes

In the recent years the development in communication systems requires the data transmission to be performed faster and faster. To meet this demand the paper presents a high speed multi channel UART controller based on FIFO (First In First Out) technique . An Asynchronous FIFO is designed with dual port ram array and with read and right pointers. The structure of controller is designed with UART (Universal Asynchronous Receiver Transmitter) and FIFO circuit design, the structure of the controller is scalable and reconfigurable design. This controller reduces the synchronization error between the sub systems in a system with other sub systems. Mainly the controller is used to operate or implement the communication system when master equipment and slave equipment are set at different baud rate.
