中文摘要: 在分析GCC结构的基础上, 阐述了GCC在C4350AL处理器上的移植与优化方案. 针对C4350AL对GCC的x86后端进行了扩展, 实现了GCC对C4350AL的识别. 根据C4350AL的结构特性, 在GCC中为建立了流水线模型描述, 并基于SPEC2006测试程序对模型效果进行了验证. 实验表明采用该模型使得GCC在C4350AL上获得了性能的提升.
Abstract:Based on the analysis of GCC's structure, the porting and optimization of GCC on C4350AL is presented. GCC's x86 backend is extended for the compiler's recognition of C4350AL. According to the properties of C4350AL's architecture, a processor pipeline model description is built. The model's effect is tested on SPEC2006 benchmark. The experiment results show that this model has improved GCC's performance on C4350AL.
