How to use Gem5?
Gem5 is primarily a computer architecture simulator. Can I use it to
simulate it for specific application wiz. encode a 4k video file (HEVC) as
input data to a LDPC encoder, followed by MQAM modulation for energy
consumption estimation? If Yes, where to start? How to create the
SimObjects?
Set up video encoding components class HEVCEncoder(SimObject):
pass
class LDPC(SimObject):
pass
class MQAMModulator(SimObject):
pass
Thank You, Regards

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.

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...
