Detailed Description

Ticked attaches gem5's event queue/scheduler to evaluate calls and provides a start/stop interface to ticking.

Ticked is not a ClockedObject but can be attached to one by inheritance and by calling regStats, serialize/unserialize

Member Function Documentation

◆ countCycles()

virtual void gem5::Ticked::countCycles ( Cycles delta )

inlinevirtual

Callback to handle cycle statistics and probes.

This callback is called at the beginning of a new cycle active cycle and when restarting the ticked object. The delta parameter indicates the number of cycles elapsed since the previous call is normally '1' unless the object has been stopped and restarted.

Parameters

delta Number of cycles since the previous call.
