双核处理器就是在一个处理器基板上集成两个功能相同的处理器核心,即将两个物理处理器核心整合入一个内核中。双核技术的引入是提高处理器性能的行之有效的方法。NiosⅡ系列嵌入式处理器使用32位的指令集结构ISA,完全与二进制代码兼容,它是Altera公司的第二代软核嵌入式处理器,性能超过200DMIPS.使用Altera公司的NiosⅡ处理器和SOPC Builder开发工具能快速地设计并实现资源共享的双核系统。
Dual-core processors are the integration of two processor cores with the same function on one processor substrate, that is, integrating two physical processor cores into one core. The introduction of dual-core technology is an effective way to improve processor performance. Nios Ⅱ series of embedded processors using ISA 32-bit instruction set, fully compatible with the binary code, which is Altera’s second-generation soft-core embedded processor, performance of more than 200DMIPS. Using Altera’s Nios Ⅱ processor and SOPC Builder Development Tools Dual-core systems that enable rapid design and resource sharing.
