Hello everybody

 

I am new comer in gem5.  My project needs me to modify ISA for simulator. I
found on the website
http://www.m5sim.org/Defining_ISAs_%28as_of_M5_2.0_beta_3%29 which is about
defining ISAs. There are several questions about this article.  

 

A.       What's this command "Perl -pe s/Mips/My/g ????" mean?   I don't
know Perl and don't understand "????". 

B.      Should I use M5 as same as gem5? Should I use one of them or both?  

C.      If I don't need to use M5, how can I build my own ISA for using?

 

Thank everyone

 

Chuan
