  Abstract &
The Godson-1 processor is a general purpose high performance processor developed in Institute of Computing Technology, Chinese Academy of Sciences. This paper first gives the
background and considerations of designing the Godson series of microprocessors. It then introduces the architecture of the Godson-1 processor, including its out-of-order instruction pipeline, precise exception strategy, branch prediction, memory management, and security design to avoid buffer-overflow attack. Test and performance analysis show that the dynamic instruction pipeline of the Godson-1 processor is efficient and its security design can effectively defense network attack based on buffer-overflow technique. However, the cache of Godson-1 processor is not large enough and its organization could be improved .
