复旦大学：《计算机原理 Computer System》课程PPT课件_09、10 Sequential CPU Implementation

Data Hazards ◼ Instruction having register R as source follows shortly after instruction having register R as destination ◼ Common condition, don’t want to slow down pipeline Control Hazards ◼ Mispredict conditional branch ⚫ Our design predicts all branches as being taken ⚫ Naïve pipeline executes two extra instructions ◼ Getting return address for ret instruction ⚫ PIPE- executes three extra instructions Making Sure It Really Works ◼ What if multiple special cases happen simultaneously?
