I am trying to get the branch difference predictor code to work but am not sure about how to run the code. What tool do I use to test it? Should I just type the commands given in linux terminal? Thanks

 

The author assumes you know how to build from source code (i.e. "make").

Generally, you download and/or extract the source code into its own directory somewhere in your home tree, "cd" to that directory and type "make". Sometimes, "./configure" or "make config" is required first.

You must have build tools installed (i.e. Ubuntu: "sudo apt install build-essential").

And probably other libraries and -dev headers (of which the config script should notify you).
