双MicroBlaze软核处理器的SOPC系统设计

SOPC System Design Based on Dual MicroBlaze Soft Cores

设计了一款基于双MicroBlaze软核处理器、面向嵌入式领域的SOPC系统,在信息处理繁忙的情况下,实现两软核处理器之间的同步、通信和中断功能,提高信息吞吐率和系统灵活性,降低设备尺寸。两处理器之间通过Mutex模块实现同步功能,通过Mailbox模块实现通信和中断功能,通过共享BRAM模块实现大块通信功能,并进行了有效的功能验证。该SOPC系统在XUPV5-LX110T开发板上得到验证。测试结果表明,两软核处理器之间有效地实现了同步,通信和中断功能,达到了预期的效果,验证了方案的有效性。

This paper designs an SOPC system based on dual MicroBlaze soft cores processor for embedded system, which can realize synchronization, communication and interrupt functions between two soft cores, increase information throughput and system flexibility, and reduce the size of the equipment. It achieves synchronization between two processors through Mutex module, realizes communication and interrupt functions through Mailbox module, and bulk communication function by sharing BRAM module. It is effectively validated. The SOPC system is implemented and verified on XUPVh-LX110T development hoard. Testing results show that synchronization, communication and interrupt functions between two soft cores are effectively completed, the desired effect is achieved, and effectiveness of the design is verified.
