This is the open-source code of our SAC-based micro-architecture DSE method.
We operated this program on Windows 10 or Windows 11, python 3.8 or python 3.10. The computer memory should have at least 16 GB.
To run the program, enter the command like python main.py --width_pred 5W_721 > ./log/log_5W_721.log, where --width_pref 5W_721 refers to the DecodeWidth and the weight vector which is [0.7,0.2,0.1]. This command will autonomously search for the config files named config_ppo_5W_721.yml and config_sac_5W_721.yml to fulfill the hyperparameters, then execute all DSE methods.
In the log file, search for the word "projection", then you will see the projection value of the "best-found micro-architecture design" in each trial. The form of the message is like this:
best_design: [[1 1 1 3 3 2 3 3 4]], best_design_ppa: [[9.5114400e-01 2.6484000e-02 1.4600115e+06]], projection: [0.03823456]
If the message is like this:
No design is in the constraint! All `proj_with_punishment` < 0.
best_design: [1. 1. 1. 2. 3. 2. 1. 2. 4.], best_design_ppa: [[9.4688803e-01 2.6484000e-02 1.4524475e+06]], projection: -0.02232724337502704
it means the method could not search for a micro-architecture design that is within the constraint.
The configuration files are in the path ./config/. Please note that the file called config_ppo_xxx and the file called config_sac_xxx should be modified simultaneously.
