Q. An operating system sustains a paged virtual memory using a central processor with a cycle time of 1 microsecond. It costs an additional one microsecond to access a page other than the current one. Pages have 1000 words as well as the paging device is a drum that rotates at 3000 revolutions per minute and transfers one million words per second. The subsequent statistical measurements were obtained from the system:
Compute the effective instruction time on this system assuming that the system is running one process only in addition to that the processor is idle during drum transfers.
Answer:
Effective access time = 0.99 × (1 μ sec + 0.008 × (2 μ sec)
+ 0.002 × (10,000 μ sec + 1,000 μ sec)
+ 0.001 × (10,000 μ sec + 1,000 μ sec)
= (0.99 + 0.016 + 22.0 + 11.0) μ sec
= 34.0 μ sec
