Detailed Description

This class represents cost estimates for a machine configuration.

Class stores estimates of area (in gates), longest path delay (in nano seconds) and energy consumptions (in milli joules) when the configuration is used to run different programs. Area and longest path delay are constants to one configuration while there can be multiple programs executed so multiple energy consumption estimations and cycle counts as well. Each energy consumption is bound to one program.
