Detailed Description

Interface to allow modeling cycle-by-cycle operation simulation behaviors.

Used by MultiCycleOperationExecutor and the SystemC integration layer (tce_systemc.hh).

Note: each instance should be used to model the operation pipeline of a single FU only. Otherwise multiple cycle start notifications will be recevied.

Constructor & Destructor Documentation

virtual DetailedOperationSimulator::~DetailedOperationSimulator ( )

inlinevirtual

52 {}

virtual void DetailedOperationSimulator::simulateCycleStart ( )

inlinevirtual

This is called once at the beginning of the TTA instruction cycle before any simulateStage() calls for that cycle.

Useful for initializing signals to their default values etc.

77 {}

virtual bool DetailedOperationSimulator::simulateStage ( ExecutingOperation & operation )

pure virtual

Simulate a single stage in the operation's execution.

This can be used in more detailed simulation models (SystemC at the moment) to more accurately simulate each stage of operation's execution.

Parameters

operation	The operation being simulated.
cycle	The stage/cycle to simulate, 0 being the trigger cycle.

Returns: Return true in case the simulation behavior was overridden by the method implementation. In case false is returned, the default behavior simulation is performed (by calling the OSAL TRIGGER at cycle 0 to produce the results and just simulating the latency by making the result(s) visible at correct time).
