Abstract
A Local Dynamic Power Controller (LDPC) generates and deliver to a load a full swing voltage supply signal and a reduced swing voltage supply signal. Both the full and reduce voltage supply signals are generated from a single power supply. The full swing voltage supply signal is supplied when the load is in full operational mode whereas the reduce voltage supply signal is provided when the load is in a sleep mode. As a consequence, power dissipated in the load is reduced.
Claims14
A system comprising:
- a semiconductor module operable to provide a particular function;
- a controller operatively coupled to said semiconductor module, said controller including a first circuit arrangement responsive to a control signal to apply a full power supply voltage to said module;
- and
- a second circuit arrangement responsive to said control signal to generate a reduced power supply voltage from said full power supply voltage and applying said reduced power supply voltage to said semiconductor module.
