Consider an unpipelined or single-stage processor design. At the start of a cycle, a new instruction enters the processor and is processed completely within a single cycle. It takes 1,000 ps to navigate all the circuits in a cycle. Therefore, for this design to work, the cycle time has to be at least 1,000 picoseconds.
1. What is the clock speed of this processor?
2. What is the CPI of this processor, assuming that every load/store instruction finds its instruction/data in the instruction or data cache?
3. What is the throughput of this processor (in billion instructions per second)?
