摘　　要：文中设计的多核系统是基于Microblaze软核,通过平台FPGA设计技术实现的.核间互联采用OPB总线,每个核都有IP模块来记录编号,实现的硬件锁完成了多核的启动和多核的同步.最后将操作系统Mutek移植到该系统上,完成线程调度和任务分配.实验证明,该系统能很好地支持多核多线程,有效提高了并行处理能力.This paper designs a multi-core system based on Microblaze software core, realizing it through the platform FPGA. Using OPB bus to connect and communicate, each cores has its own IP module to record its number. Spin lock complete the multi-core＇s booting and synchronizing. Finally transplant the operator system Mutek to this system to complete scheduling threads and assigning tasks. Both experimental verification and final implement indicate this design can fulfill the multi-core and multi-thread system to increase the performance of parallel process.
