摘要
软核处理器(MicroBlaze)和外设知识产权(IP)核以及用户定制的IP核一起,可以完成片上系统(SoC)设计,适合复杂嵌入式系统的开发,同时为系统将来的专业集成电路(ASIC)设计提供基础。围绕赛灵思(Xilinx)公司的MicroBlaze微处理器,对其体系结构、设计流程和赛灵思微处理器调试(XMD)方法进行了详细讨论。结合GPS接收机设计实例给出了嵌入式系统开发的仿真和集成开发环境(ISE)下调用软核的设计方法,并讨论了影响系统实时性的链接脚本文件设置中的关键问题。
The SoC design can be implemented by integrating MicroBlaze,peripheral IP core and customized IP core,which,suitable for the sophisticated embedded system development,could provide a foundation for the future ASIC design.The architecture,design flow,and XMD-related debug methods of the MicroBlaze microprocessor from Xilinx company are discussed in detail.And,with a design example of GPS receiver,the simulation of embedded system development is given,and the key techniques of linker script document affecting real-time performance of GPS receiver system are elaborated.
