本文介绍了一种通用异步收发器（ＵＡＲＴ）芯片的总体设计方案，重点讨论了其中的主要模块：波特率发生器、发送器、接收器及红外通信（ＩｒＤＡ）接口的设计，并用ｖｅｒｉｌｏｇ硬件描述语六对所设计的芯片的功能进行了仿真验证。仿真结果表明我们设计的ＵＡＲＴ芯片达到了预定的设计要求。
This article describes a general asynchronous receiver / transmitter (UART) chip design, focusing on one of the main modules: baud rate generator, transmitter, receiver and infrared communications (IrDA) interface design, and verilog hardware Descriptors Six of the design of the chip functions were simulated. Simulation results show that we design the UART chip to meet the predetermined design requirements.
