一种基于McBSP接口分时复用的背板总线
摘要：
本实用新型涉及一种基于McBSP接口分时复用的背板总线，包括数字信号处理器DSP模块、背板总线接口模块和背板总线逻辑控制模块；数字信号处理器DSP模块、背板总线接口模块和背板总线逻辑控制模块均设置于电力电子控制器CPU板卡上；CPU板卡的数量至少为2；所述背板总线逻辑控制模块分别与数字信号处理器DSP模块和背板总线接口模块连接。本实用新型充分利用数字信号处理器DSP的多通道缓冲串行外设接口McBSP，为电力电子控制器各个板卡DSP间的实时数据交互提供一种简单有效的解决方案。
摘要（英）：

The utility model relates to a backplane bus based on multichannel buffered serial port (McBSP) time-sharing multiplexing. The backplane bus based on the McBSP time-sharing multiplexing comprises a digital signal processor (DSP) module, a backplane bus interface module and a backplane bus logic control module, the DSP module, the backplane bus interface module and the backplane bus logic control module are all arranged on central processing unit (CPU) board cards of a power electronic controller, the number of the CPU board cards is at least two, and the backplane bus logic control module is respectively connected with the DSP module and the backplane bus interface module. An external McBSP of the DSP module is fully utilized for providing the simple and effective solution scheme for real-time data interaction among DSPs of the board cards of the power electronic controller.
