Godson-3B has an energy efficiency of 3.2GFLOPS/W.
Other state-of-art high-performance processors have energy efficency of
~1.3GFOPS/W (Westmere [2]) and ~1.5GFLOPS/W (Power7 [3,4]). As shown in
Fig. 4.4.1, Godson-3B contains 2 nodes while being able to scale to 16 nodes
through inter-chip connection. Each node contains four cores, four L2-cache
banks, one HyperTransport (HT) controller, one DDR2/3 controller, and the inter-
connection network connecting these components together. The interconnection
network takes the 128-bit AXI standard interface with cache coherence exten-
