大功率UPS中DSP与单片机的串行通信设计

The Design of Serial Communication between DSP and SCM on High-power Uninterruptible Power Supply

在全数字化高频大功率UPS中,大都采用两片或多片DSP与单片机共同完成较为复杂的控制和监控任务。本文主要就SCI串行通信接口实现DSP与单片机串行通信展开讨论,并给出了利用SPI实现串行通信的设计方案,分析比较了两种通信方式的异同,给出了DSP与单片机串行设计的基本方法。

In total number high frequency High-power UPS, there are two or more pieces DSP and SCM accomplishing the missions which are complicate controlling and stakeouting. This paper mainly discusses the interfaces between DSP and SCM in SCI serial communication,at the same time this paper presents the design of SPI serial communication and analyses the different between the two modes, contemporary presenting the basic way of serial communication design.
