基于NUCA结构的同构单芯片多处理器

非一致Cache体系结构(NUCA)几乎已经成为未来片上大容量Cache的发展方向。本文指出同构单芯片多处理器的设计主要有多级Cache设计的数据一致性问题,核间通信问题与外部总线效率问题,我们也说明多处理器设计上的相应解决办法。最后给出单核与双核在性能、功耗的比较,以及双核处理器的布局规划图。利用双核处理器,二级Cache控制器与AXI总线控制器等IP提出一个可供设计AXI总线SoC的非一致Cache体系结构平台。

Homogeneous Chip Multiprocessor based on NUCA Architecture

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, ...
