写后直接读 - A raw ( read after write ) dependency loop model is developed in this paper to analyze the raw hazards of register operands in complex pipeline . based on this model , a " dynamic " data forwarding policy is suggested to reduce the pipeline stalls caused by data raw hazards . theoretical analysis and practical experiments both show that the average cpi increment caused by data raw hazards can be reduced effectively by the dynamic data forwarding strategy
对于单发射结构的处理器，降低cpi值的根本途径在于通过各种软硬件技术减少流水线的停顿，本文构造了一个raw相关环路模型用于分析流水线中寄存器操作数的raw竞争现象，并提出了一种“动态”数据旁路优化策略，可以最大程度地减少复杂流水线中因数据的raw竞争而导致的互锁停顿，理论分析和实测结果充分表明“动态”数据旁路机构可以有效地降低流水线因raw互锁导致的平均cpi增量。
