Incrementing By More Than 1
For scenarios where it is desired to increment a count by more than one on a single
clock tick, the
PMON
unit can be sent a “bit encoded” value. This allows the counters to
track an increment/decrement of up to 2
N-1
each clock tick, where N is the number of
counters available. For example, with 8 counters we could track an
increment/decrement of up to 128 (2
7
) each clock.
This would be done by assigning an array of events to represent a particular value to
count. The counters would be coordinated to mimic a single counter which by asserting
the appropriate event signals cause the set of counters to be incremented and/or
decremented by the in such a way that post processing of the counter values.
