Detailed Description

Models the latency of an operation result.

This is used to make results visible in the output ports of the FU at the correct time.

advanceCycle()

void ExecutingOperation::PendingResult::advanceCycle

(

)

Signals a cycle advance.

Makes the result visible to the output port in time.

    if (--cyclesToGo_ == 0) {
        target_->setValue(*result_);
        cyclesToGo_ = INT_MAX;
