Consider a 64-bit, 50 MIPS CPU with which following I/O devices are attached.

 

  1. A hard drive having a 32-bit bus and maximum transfer rate of 12 MB/sec.
  2. A DVD writer having a 32-bit bus with transfer rate of 1 MB/sec.
  3. A mouse having the polling frequency of 100 Hz.

 

Assume that one polling operation requires 12 instructions for each I/O device. You are required to calculate the percentage of CPU time required to poll each of the given devices.

 

Question 2                                                                                                       Marks 10    

 

Suppose we have a magnetic disk with an average seek time of 3ms. The disk can transfer at a maximum rate of 30 MB/sec. If disk rotates at 18,000 rpm and the controller overhead is 0.5ms, then calculate the average time to read or write a data block of 1 MB.
