Detailed Description

A Equation power model.

The power is represented as a combination of some stats and automatic variables (like temperature).

Member Function Documentation

double MathExprPowerModel::eval ( const MathExpr & expr ) const

private

Evaluate an expression in the context of this object, fatal if evaluation fails.

Parameters

expr	Expression to evaluate

Returns: Value of expression.

Referenced by getDynamicPower(), and getStaticPower().

double MathExprPowerModel::getDynamicPower ( ) const

inlinevirtual

Get the dynamic power consumption.

Returns: Power (Watts) consumed by this object (dynamic component)

Implements PowerModelState.

Definition at line 69 of file mathexpr_powermodel.hh.

References dyn_expr, and eval().

double MathExprPowerModel::getStaticPower ( ) const

inlinevirtual

Get the static power consumption.

Returns: Power (Watts) consumed by this object (static component)

Implements PowerModelState.

Definition at line 76 of file mathexpr_powermodel.hh.

References eval(), and st_expr.

double MathExprPowerModel::getStatValue ( const std::string & name ) const

Get the value for a variable (maps to a stat)

Parameters

name	Name of the variable to retrieve the value from

Returns: Power (Watts) consumed by this object (static component)

void MathExprPowerModel::regStats ( )

virtual

Register statistics for this object.

Reimplemented from SimObject.

Definition at line 153 of file mathexpr_powermodel.cc.

References PowerModelState::regStats().

void MathExprPowerModel::startup ( )

virtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from SimObject.
