Homogeneous Chip Multiprocessor based on NUCA Architecture
Lin Chang · China Integrated Circuit · 2011
Non-Uniform Cache Architecture (NUCA) has almost been the trend of large cache designs.In this paper, we point out the main problems for CMP design which are cache coherence,inter-processor communication and external bus efficiency problems. We highlight the solutions for all the problems. Finally we provide the benchmark about performance and power consumption for single-core and dual-cores processors as well as the floorplan of the proposed dual core processor design. We assemble the dual core processor, L2 cache controller and AXI system bus controller to form the NUCA architecture which can apply for any AXI-based SoC design.
