[gem5-users] Re: How to use Gem5?
Hi, I want to compute the power consumption of the processor, while encoding data. (power consumed by an specific application like encoder/decoder) I have python script for the encoder. (Creating the SimObject is yet a task for me, I am going through the video available on YouTube for creating theSimObject.) The stats and output are stored in m5out stats.txt file. But I don't know how power will be computed. What should be the command I should give to run my script? Kindly help. Thank you...

Hi Anamika, Hey there. The se.py script has been depreciated in favor of the new gem5 standard library. You can find examples of using the standard library, https://github.com/gem5/gem5/tree/stable/configs/example/gem5_library. The internal of the standard library (how components are constructed and connected) are here, https://github.com/gem5/gem5/tree/stable/src/python/gem5. Regarding developing a simulation component (or a SimObject), which is a media decoder accelerator in your case, you can start from learning gem5 here, https://www.gem5.org/documentation/learning_gem5/part2/helloobject/, or the tutorial from 2022 gem5 bootcamp, https://youtube.com/watch?v=OcXA1D4b1RA. At a high level, every SimObject has a Python class that is binded to a C++ class. The Python interface provides a way for you to input the parameters to your component and to connect SimObjects. You'd need to implement the C++ part, which performs the functionalities of the SimObject, like decoding a stream of bits.

[gem5-users] Re: How to use Gem5 to collect instruction traces
Hi Setu, It might depend on the ISA you are using. You can generate an instruction trace by running gem5 with --debug-flags=Exec option and this is valid for all ISAs. If you are simulating an Arm CPU, an instruction trace in the Tarmac format can also be generated.

How can I generate traces using Gem5, and what format are the traces in?
