Abstract

In order to solve the problem that the receiver needs to make baud rate agreement with the sender every time when the sender's baud rate is variable during serial transmission,the UART adaptive reception IP core is designed in the paper.The baud rate library inside the FPGA is set up,and accurately identifies the baud rate by using the 0check digit and the duration of the idle bit,realizing the adaptive reception of the UART.At the same time,the whole module is encapsulated into an IP core based on VHDL,which further improves the generality of the design.The simulation is performed by Vivado internal simulation tool,and the results show that this design can perform adaptive reception of UART under the set baud rate library.
