2. (30 points) Consider the single-cycle datapath with the following component latencies: (note that the register file and memories have different latencies for reads and writes.) Functional Unit Time (ns) Memory (read) Memory (write)12 ALU Register File (read) Register File (write) 7 Which instruction (add, sw, lw, beq) will take the most time to execute on this single-cycle datapath, which components of the datapath will it use, in what order will it use them? a) b) Calculate the cycle time for a single cycle datapath
