2. [8 marks] - Performance analysis of Pipelined Instruction Execution microprocessor (uniform and non-uniform stage lengths)
Part 1
- minimum clock cycle time: 600/8 ps + 30 ps = 75 ps + 30 ps = 105 ps
- latency: (600/8 ps + 30 ps) 8 = (105 ps) 8 = 840 ps, 1 intruction takes 840 ps to execute, to go through all 8 stages of its execution
