主题: explaination about command_window in MemCtrl.py
Hi all:
Now I’m working on researching LPDDR5 feature on GEM5.
But I do not clearly know the parameter ”command_window“ in MemCtrl.py, and why
the default value set to 10ns.
In a workshop vedio for “Memory controller for LPDDR5”, there is a formula
“maxCommandsPerBurst = burst_length / beats_per_clock”, but I have found in
code in v21, there is a formula “maxCommandPerWindow = command_window / tCK” in
MemInterface::setCtrl, what is the difference between “maxCommandsPerBurst” and
“maxCommandPerWindow”?
Best regards
