[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...

[gem5-users] 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 Anamika ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org
