| 摘 要： | 同/异步串口集成了同步和异步串口的功能,相比于单一功能的串口,配置灵活,且节约芯片资源。通过模块化设计方法实现同/异步串口的设计与仿真,并着重在内部模块设计中体现同步和异步功能的有效结合,合理复用逻辑功能。利用寄存器实现模块同异步功能及参数的可配置性,设计实现了9位唤醒模式,以支持多处理器通信。逻辑综合的结果显示,该串口具有良好的性能。目前,该串口已应用于高端32位DSP,工作稳定。 |

| Abstract: | Synchronous/Asynchronous Serial Interface(SASI) has the function of both synchronous and asynchronous serial interface.Compared with single functional serial interface,SASI has flexible configuration and saves chip area.An SASI circuit was designed and simulated by using modularized design method,which focused on the effective combination of synchronous function with asynchronous function by reasonable multiplexing logic.The configuration was realized by registers,and 9-bit wake-up mode was implemented to support multi-processor communication.The synthesis result indicated that the interface had good performance.The SASI has been applied to an advanced 32-bit DSP and it functions properly. |
