complete all parts and show work 5. Consider the identical computer to the one in question 4, but now the sectors are transferred from disk cache to main memory by using processor-involved software transfers, instead of DMA. The transfers are done by a loop in assembly for the form: loop: LW * from memory-mapped disk cache address* SW ADDI BNEZ ..,_Loop to main memory * /* register increment for address register to main memory /* branch back to LW for next iteration for next word */ Memory mapped locations are not cached by the processor caches. Further, the processor caches use write through for main memory locations. The branch predictor is perfect. What is the total transfer time in software for the sector? How many times faster is DMA in question 4 compared to this software transfer? complete all parts and show work 5.
