基于NIOS Ⅱ双软核智能家居控制器设计

Design of the Intelligent Home Controller Base on Double NIOS Ⅱ Soft Core Processor

多核技术是当今处理器发展的主流,是提高系统性能的一项重要技术。多核技术使嵌入式系统朝着速度更快、价格更便宜、耗能更小的方向发展。系统利用Altera公司的Nios Ⅱ处理器和SOPC Builder开发工具,在一块FPGA芯片上实现了可配置、可裁减的双软核处理器的智能家居控制器,提高了智能家居控制器的安全性、可靠性和实时性。重点分析了双核共享内存和双核启动的问题。实验结果表明,该控制器切实可行,且易于进一步地开发和升级。

Multi core technology is the mainstream of the processor development,is an important technical to improve the system property.Multi core technology to accelerate the embedded system development toward the faster,cheaper and less energy consumption.Using Altera＇s Nios Ⅱ processor and SOPC Builder development kit,realized the intelligent home controller base on double soft core processors to be configured and cut out in a piece of FPGA chip.Improved the intelligent home controller reliability and real-time.Focus on the analysis the problem of the duo shared memory and dual boot.The experimental results show that,the controller is feasible,and is easy to further develop and upgrade.
