AI Technical Summary
In existing industrial control systems, multiprocessor systems suffer from limitations in bus resources, poor data real-time performance, inflexibility, and poor scalability, as well as problems such as bus access conflicts and data asynchrony.
It adopts a star topology connecting the programmable bus protocol controller, processor, and peripheral modules. It realizes a multi-master switching high-speed interconnect backplane bus through virtual address translation, allowing multiple processors to access and multiple peripheral modules to operate concurrently, reducing the data packet collision rate, improving bus efficiency, and system scalability.
It achieves the aggregation of multi-processor computing power, improves bus throughput and system real-time performance, reduces backplane bus complexity, enhances the system's flexible configuration capabilities, and is suitable for various industrial control application scenarios.
