摘要：A UART (Universal Asynchronous Receiver / Transmitter) is a serial communication protocol; widely used for low speed, low-cost, short-distance, full duplex data exchange between computer and an output device. During transmission, UART, the Data Communication Equipment (DCE) converts the bytes from the Data Terminal Equipment (DTE) parallel bus to the serial bit stream and during reception, the UART builds the serial bits into a parallel byte sent to the another DTE. For data integrity, the existing UART designs are incorporated with error detection logic. But to correct the received erroneous data, the retransmission of corresponding data frames via the ARQ (Automatic Repeat Request) is the only option available with the existing logic. This paper presents the overview of different techniques to mitigate errors forreliable data communication in UART
