11. What is Branch instruction. (i) Determine the number of Clock cycles that it takes to process 200 tasks in a six-segment pipeline. (ii) A nonpipeline system takes 50ns to process a task. The same task can be processed in six-segment pipeline with a clock cycle of 10ns. Determine the speedup ratio of pipeline for 100 tasks. 12. Consider a hypothetical Control unit which supports 4K words. The Hardware contains 64 control signals and 16 Flags. What is size of control word used in bits and control memory in byte using: (i) Horizontal Programming (ii) Vertical Programming.
