Modify the code in Figure 5.32 to measure the following system characteristics. Plot the experimental results with elapsed time on the y-axis and the memory stride on the x-axis. Use logarithmic scales for both axes, and draw a line for each cache size.
a. Is the L1 cache write-through or write-back?
b. Is the memory system blocking or nonblocking?
c. For a nonblocking memory system, how many outstanding memory references can be supported?
