Extracted text: A CPU has 6 stages pipeline and runs at 1 GHz frequency. Instruction fetch happens in the first stage of the pipeline followed by instruction decode, calculate effective address, fetch operands, execute instruction and write back. A conditional branch instruction computes the target address and evaluates the condition in the fourth stage of the pipeline. The processor stops fetching new instructions following a condition branch until the branch outcome is known. A program executes 1010 instructions out of which 30% are conditional branch. If each instruction takes 2 cycle to complete on average, then total execution time of the program in seconds
