We are using a special keyboard that allows for both polling and interrupts, and would like to determine whether polling or interrupts is better. Through analysis, we have determined that we type at an average rate of 5 characters/second, but sometimes we end up typing two characters near-simultaneously, with only 10 microseconds between inputs. We have also determined that our system runs at a 100 MHz clock frequency our computer is really really slow), and our OS/program runs with Y=400, Z=9600. We want to ensure that all characters we type are successfully captured, assuming that at least 10 microseconds elapse between keystrokes. 2a. What is the maximum value of X that allows polling to work? integer
2b. If we decide to use polling with the maximum X we determined in 2a, what is the fraction of our clock cycles that we spend polling? number (stol-0.01, atol=1e-08)
2c. Over 100 seconds, what is the average number of cycles spent running interrupts, if we decide to use interrupts? integer
2d. If we decide to use interrupts, what is the fraction of our clock cycles that we spend handling interrupts? number (rtol=0.01, atol=14-08)
