Shortest response time

Conditions for the shortest response time
The figure below shows the conditions under which the shortest response time is reached.
Calculation
The (shortest) response time is the sum of:
Table 5-10

+
=
The result is equivalent to the sum of the cycle time plus the I/O delay times.
