摘　　要：针对航天工程领域中对远距离遥测遥控的需求,本文设计实现了一种基于AMBA2.0APB总线的三线制同步串行通信接口.该接口采用独立的收/发数据通道,在门控和同步时钟的约束下同外设进行串行数据的传输.接收器在同步时钟的上升沿采集数据;发送器在时钟下降沿送出数据.接口内部收/发器集成了FIFO,实现了对收发数据的缓存功能.目前该接口实际应用,可有效满足数据通信的功能性和效用性要求.According to application requirement for remote telemetry and telecommand in aerospace engineering field, this paper has designed a three-wire synchronous serial data interface on AMBA 2. 0 APB bus. In the constraints of gating and synchronous clock signals, the interface transfer serial data with peripheral equipment through independent data transceiver channels. At the rising edge of synchronous clock, the receiver collect data; at the falling edge of synchronous clock, the transmiter transmit data. Because of the FIFO integrated in the interface the design achieve the data buffer function. At present the interface has been applied in practical projects, and can largely meet the requirements for the functions and efficency in data communication.
