Consider the execution of ten instructions 11-110 on a pipeline consisting of four pipeline stages: IF, ID, IE, and IS. Assume that the instruction 14 is a conditional branch instruction and that when it is executed, the branch is not taken, that is the branch condition is not satisfied. Assume also that when the branch instruction is fetched, the pipeline stalls until the result of executing the branch instruction is stored. Show the succession of instructions in the pipeline and the bubble created using Gantt. May 26, 2016 Read More »
