Method and apparatus for selectively assigning circuit data to a plurality of programmable logic circuits for maintaining each programmable logic circuit within an operation range at a minimum voltage

Abstract

Programmable logic circuits are changeable circuit components based on circuit data. A circuit data memory stores a plurality of circuit data and performance requirements. A feature data memory stores feature data of each programmable logic circuit. A control unit calculates a minimum voltage of the plurality of programmable logic circuits to execute the plurality of circuit data based on the performance requirements, and selectively assigns the plurality of circuit data to the plurality of programmable logic circuits so that the performance requirement of circuit data assigned to each programmable logic circuit is within the operation range of the programmable logic circuit at the minimum voltage. A supply unit supplies the minimum voltage to the plurality of programmable logic circuits.
