We implemented a new 5-stage pipeline with the following features: the delay by data and control hazards are as follows: 1 cycle stall for the load by immediate use, 2 cycle stalls for branch taken. Assume we now run 10,000 instructions on the pipeline, among them: (1) 35% are lw instructions. 10% of lw instructions are followed by instructions that use lw result immediately in ALU input; (2)15% are branch instructions with 40% possibility of branch taken; (3) the remaining...
