Design of Multichannel UART Controller with AXI4.0 Lite Interface

Abstract

UART (Universal Asynchronous Receiver Transmitter) is basically used for long distance slow speed serial communication. When it comes to latest SOC high speed communication design single channel requires more time and lots of interrupt to process the data. To overcome this disadvantage here high speed multi channel UART controller has been implemented which will be used for avoid synchronization error between and high speed master and different slave devices. AMBA AXI4.0-Lite high speed bus is also interfaced with UART Controller. AXI4.0 is reconfigurable and can be updated to any other high speed bus in future. Whole design is simulated using Verilog HDL in Questasim 10.0b software with the help of verilog testbench.
