Now assume you have 2 SS CPUs. How many cycles will it take to execute these two threads? How many issue slots are wasted due to hazards?

B) are too expensive. How will removing the forwarding paths qualitatively effect the 3 terms in the CPU Performance Iron Law equation? For each term explain term below, explain why it will increase, stay the same, or decrease. If it depends on other factors, explain those too. You can You are considering removing the forwarding paths from your processor because they assume your processor is pipelined with full forwarding (initially) and it is executing a generic workload. (i) Instruction count (ii) CPI (iii) Clock Period

Calculate the speed up factor provided by Machine C over Machine B

Suppose you now own two SS CPUs. How many cycles will these two threads need to execute? How many issue slots are lost due to potential risks?
