Hello Arthur,
Seems like a good approach, I'll give it a try! thanks for your help.

Subject: Re: [gem5-users] gem5 CPU clock question
Hello Raul,
How about putting a latency of 5 and making it not pipelined?
For instance, in O3_ARM_v7a.py:
class O3_ARM_v7a_Simple_Int(FUDesc):
opList = [ OpDesc(opClass='IntAlu', opLat=5, pipeline=False) ]
count = 2
So, naturally, this is the quick and dirty way to do it, but you'll have a
throughput of 1 ALU operation every 5 processor clocks (well, 2 since there are
two units here), unless I am mistaken.
You'll note that it only works one way (CPU faster than ALU).
Best,
Arthur.

Hello gem5 users,
I'm new to gem5, I would like to know if is it possible to generate a
configuration where the system runs at a 1 GHz with exception of the ALU which
is configured to run at a different frequency e.g. 200 MHz?
Regards,
Raul.
