实现系统规模化的龙芯3号桥片设计与验证
Implementation for large-scale system of Godson-3 bridge chip design and verification
摘要
Abstract
CC-NUMA(Cache Coherent Non-Uniform Memory Access)applied on Godson-3A processors has got a good performance, programming, as well, significantly simplified. However, keeping on-chip and off-chip data transmission stable and accurate, also has some work that needs to continue analyzing and studying on the structure of chip-to-chip intercon-nection based on coherence protocol. In order to construct for larger scale expansion of CC-NUMA system, coherence should be kept among multiple processors. With the bridge chip, it gathers to control and guarantees global data coherence for crossing systems, and improves the performance of memory access. The bridge chip designed is partly similar to the Godson3A’s second level cache. The function of the bridge chip is verified through the directional and random test.关键词
