Abstract:
1. A method comprising: operating an integrated circuit using a first supply voltage level, wherein the integrated circuit is in a mobile computer; transmitting, from the integrated circuit to a voltage regulator, an indication of a second supply voltage level to be provided to the integrated circuit; receiving the second supply voltage level from the voltage regulator; and operating the integrated circuit using the second supply voltage level, wherein the integrated circuit does not change operating modes during transition between operation at the first supply voltage level and the second supply voltage level, wherein the voltage regulator provides multiple intermediate supply voltages between the first supply voltage level and the second supply voltage level, wherein the multiple intermediate supply voltages have programmable multiple intermediate intervals and programmable multiple intermediate operating voltage levels, and wherein operating the integrated circuit using the second supply voltage level includes waiting a programmable dwell time for changing an operating frequency of the integrated circuit.
