摘要
本文结合设计需求,提出了一种SPI主模式的接口电路设计,使其可以在多种SPI传输模式下进行数据的传输,且针对实时信息处理占用时间较长的不足,采取信息自动加载方法,有效降低了处理器占用时间。设计并搭建仿真验证平台对其进行验证。仿真测试结果表明,该SPI总线接口电路满足实际应用需求。
According to the actual requirement, a host SPI interface circuit design is proposed, which supports all transmission modes. The auto-load method is used to reduce the processing time. The simulation verification platform is built for SPI bus controller simulation ver- ification. The verification results show that the SPI bus interface meets the practical application requirements.
