To construct a rational and efficient communication structure and a high-efficient data storage path for CMP system,a kind of scalable and configurable CMP architecture utilizing multi-channel Cache(AUMCC) is proposed in this article and its prototype system is established based on FPGA and LOEN3 processor.Multi-channel Cache is adopted as L2 Cache in AUMCC.AUMCC can be configured to be private L2 Cache structure or shared L2 Cache structure based on the access mode of multi-channel Cache.Simulation and testing results show that AUMCC architecture can achieve about 37% performance improvement compared with shared L2 Cache BUS-centric(SCA) architecture,and the hierarchy characteristic of AUMCC assures the good scalability.
