// This is a generic implementation of the Metronome Architectural Protocol that
|
||
|
|
// layers on top of an instance of the Timer Library. The Timer Library provides
|
||
|
|
// functions for nanosecond and microsecond delays. This generic implementation
|
||
|
|
// produces a fixed TickPeriod of 100ns unit, and when the WaitForTick() service
|
||
|
|
// is called, the number of ticks passed in is converted to either nanosecond or
|
||
|
|
// microsecond units. If the number of ticks is small, then nanoseconds are used.
|
||
|
|
// If the number of ticks is large, then microseconds are used. This prevents
|
||
|
|
// overflows that could occur for long delays if only nanoseconds were used and also
|
||
|
|
// provides the greatest accuracy for small delays.

The Timer Library provides functions for nanosecond and microsecond delays. This generic implementation produces a fixed TickPeriod of 100ns unit, and when the WaitForTick() service is called, the number of ticks passed in is converted to either nanosecond or microsecond units.
