Five microarchitectures for designing these processors. Comment on their advantages/ shortcomings and identify the names of two example commercial processors that are built in each processor category. Assume a single core in the superscalar processor and the three multithreaded processors. The last processor category is a multicore CMP and each core is assumed to handle one thread at a time.
