Hi Le Minh Son, In my opinion, if you are well aware of the ISA specs and know how your new instruction will fit in with the existing instructions, you might add a real instruction. Otherwise, adding a pseudo instruction might be a better option. Following are some of the references that you might find useful while trying to add instructions in gem5 (please, note that some might be a bit outdated):
