Re: [gem5-users] Difference cpu clock and sys clock
Hi Jason Thank you for the insight. I have already gone through part 1 of the tutorial but will revisit it again and study it in more details. Best regards J.Osmany From: gem5-users [mailto:gem5-users-boun...@gem5.org] On Behalf Of Jason Lowe-Power Sent: 27 November 2019 16:38 To: gem5 users mailing list Subject: Re: [gem5-users] Difference cpu clock and sys clock Hi Javed, Just to follow up a bit, I suggest you dig into how the configuration scripts work. Most objects are "ClockedObjects" and each ClockedObject can have its own clock. By default, the clock of a child object (e.g., cpu is the child of system if you say system.cpu = TimingSimpleCPU()) is the same as its parent. The Learning gem5 book Part I which covers configuration scripts may be helpful. http://learning.gem5.org/book/part1/simple_config.html Cheers, Jason On Wed, Nov 27, 2019 at 7:47 AM Javed Osmany mailto:javed.osm...@huawei.com>> wrote: Hello Abhishek Tks for the info.
