POWER MANAGEMENT FOR PROGRAMMABLE LOGIC DEVICES

A programmable circuit is provided with a number of current regulating circuits, such as sense amplifiers, by which the user can regulate the amount of current drawn by any of a number of circuit functions within the programmable circuit. Additional current regulating circuits are associated with circuit elements which can be programmably shared between one or more circuit functions. The user can therefore programmably control the current consumption, and thereby the speed, of each circuit function as well as circuit functions interacting via the shared circuit elements.
