Detailed Description

Models an operation executing in the FU pipeline.

This is a helper class used by MultiCycleOperationExecutor to produce a more detailed simulation of operations executing in the FUs. Notably, this model is used in the interface to override operation simulation models from SystemC simulations (see tce_systemc.hh).

advanceCycle()

void ExecutingOperation::advanceCycle

(

)

Should be called at the end of a simulation cycle.

Definition at line 73 of file ExecutingOperation.cc.

    for (std::size_t i = 0; i < pendingResults_.size(); ++i)

io()

SimValue & ExecutingOperation::io

(

int

operand

)

Returns the value bound to the input or output operand with the given ID.

Note

operand is the OSAL ID, thus 1 is the first input and the outputs follow sequentially.

Definition at line 41 of file ExecutingOperation.cc.

                                  {
    return iostorage_[operand - 1];
}

References iostorage_.

isLastPipelineStage()

bool ExecutingOperation::isLastPipelineStage ( ) const

inline

Returns true in case the currently simulated stage for the operation is the last before finishing the execution.

The next advanceCycle call will push the operation out from the FU pipeline after which all results are assumed to have arrived.

Definition at line 75 of file ExecutingOperation.hh.

{ return stage_ == stages_ - 1; }

operation()

const Operation& ExecutingOperation::operation ( ) const

inline

Definition at line 63 of file ExecutingOperation.hh.

{ return *op_; }

References op_.

stage()

unsigned ExecutingOperation::stage ( ) const

inline

Definition at line 65 of file ExecutingOperation.hh.

{ return stage_; }

References stage_.

start()

void ExecutingOperation::start

(

)

Methods that should not be called from SystemC models.

Sets the operation execution to be started.

Should be called at the beginning of a single operation's simulation.

Definition at line 51 of file ExecutingOperation.cc.

                          {
    for (std::size_t i = 0; i < pendingResults_.size(); ++i) 
        pendingResults_[i].reset();

    stage_ = 0;
}

stop()

void ExecutingOperation::stop

(

)

Sets the operation execution to be stopped.

Should be called at the end of a single operation's simulation. This sets the object to be reusable for other operation execution.

Definition at line 65 of file ExecutingOperation.cc.
