Hi Zheng Wu, If you have a look in src/mem/SimpleDRAM.py you will find the following:
# Enum for memory scheduling algorithms, currently First-Come # First-Served and a First-Row Hit then First-Come First-Served class MemSched(Enum): vals = ['fcfs', 'frfcfs'] In short, you don't have a tremendous amount of choice at the moment, and FR-FCFS is the more reasonable option of the two. If you want to add additional algorithms it should not be too difficult. To select the algorithm you have to make some manual changes in the config script (e.g. FSConfig.py or se.py) where the memory controller is instantiated.
