Since cpu_side is a VectorPort, it will automatically create multiple port connections.

WebOnce the above is done, you will need to build a ARM gem5 binary. You can create multiple builds including .fast, .opt, and .debug. If you are only concerned about running experiments, it is recommended to only create gem5.fast. However, if you need to debug anything or want to generate traces, you will need to build gem5.opt or gem5.debug.
