4. Consider the following CPU organizations with 3 functional units. CPU CG: A coarse-grained multithreaded processor that allows instructions to be run concurrently, though only instructions from a single thread can be issued on any cycle. CPU SMT: A SMT processor that allows instructions to be run concurrently without restrictions. Assume we have three threads X, Y and Z to run on these CPUs that include the following operations - X1: 2 cycles; X2: 4 cycles, FU conflict with X1; X3: 2 cycles, dependent on X1 results; Y1: 1 cycle, FU conflict with Y2 and Y3; Y2: 2 cycles; Y3: 3 cycles, FU conflict with Y2; Z1: 3 cycles; Z2: 2 cycles, dependent on Z1 results; Z3: 1 cycle, dependent on Z1 results. Assuming no additional hazards and long-stalls, fill up the following table. 10 points) CPU SMT FU FU2 FU3 Cycles CPU CG 4. Consider the following CPU organizations with 3 functional units.
