a) Consider a processor that goes through the following six stages to implement the "lw" instruction that you have studied in class. The time for each stage (in ps) is also shown in the table. IF RR(Register EXE (ALU MEM WB (Register (Instruction (Instruction Read) Execution) (Memory Write Back) Fetch) Decode) Access) 200 50 75 175 200 100 ID a) State the clock cycle time (Tc) for the single cycle implementation of such a processor. Using the value of Tc, calculate the total time taken for the following instructions to execute (Given that, initially, the register $50 contains 50, and the register $s1 contains 0). loop: beg $50, $0, exit add $51, $51, $so addi $50, $50, -10 j loop exit
