So similar as the native progress of microprocessor, the multicore experiment should also be a next step following the traditional superscalar processor experiments. And the focus of new experiments should be on the different parts between superscalar and multi core processor, for example, the interconnection, cache coherence, shared memory hierarchy. Even with this top principle, how to design the hardware experiments in details still needs a lot of thinking. We leave it as an open question and call for suggestions from literature.
