摘　　要：介绍了一种双核CPU的设计,采用精简的指令系统,具有经典的五级流水线结构,支持乘除法和异常/中断处理。CPU中的两个核具有分离的指令Cache,通过共享数据Cache来进行相应的共享数据传输,各Cache之间通过仲裁器来维护访问权限。同时对该设计进行了有针对性的测试,验证双核是否能够正确工作,以及一些简单的性能分析。设计样例在相关课程的实验教学中具有很高的应用价值。Introduced the design of a double-core CPU, which uses reduced instruction set, has clas- sic five-stage pipeline and supports exception/interruption. The double cores of the CPU have the indi- vidual instruction cache and share the data cache to provide the data exchange. The cache of these two cores use arbiter to manage the memory access. The design is tested with specific test cases to validate the double core CPU working correctly. This paper gives some simple performance analysis of the CPU. This design is a valuable sample experiment for the course experiment teaching.
