Abstract
An apparatus is provided, where the apparatus includes a first domain including first one or more circuitries, and a second domain including second one or more circuitries. The apparatus may further include a first voltage regulator (VR) to supply power to the first domain from a power bus, a second VR to supply power to the second domain from the power bus, and a third VR coupled between the first and second domains. The third VR may at least one of: transmit power to at least one of the first or second domains, or receive power from at least one of the first or second domains.
Claims20
A semiconductor package comprising:
- a first domain comprising first one or more circuitries;
- a second domain comprising second one or more circuitries;
- a first voltage regulator (VR) to supply power to the first domain from a power bus;
- a second VR to supply power to the second domain from the power bus;
- and
- a third VR coupled between the first and second domains, the third VR to at least one of:
- transmit power to at least one of the first or second domains, or receive power from at least one of the first or second domains.
A system comprising:
- a memory to store instructions;
- a processor coupled to the memory, the processor to execute the instructions;
- a wireless interface to facilitate communication between the processor and another system;
- a first domain comprising one or more of the memory, the processor, or the wireless interface;
- a second domain comprising another one or more of the memory, the processor, or the wireless interface;
- a first voltage regulator (VR) to supply power to the first domain from a power bus;
- a second VR to supply power to the second domain from the power bus;
- and
- a third VR coupled between the first and second domains, the third VR to perform at least one of:
- transmit power to at least one of the first or second domains, or receive power from at least one of the first or second domains.
A method comprising:
- supplying, by a first Direct Current (DC) to DC converter (DC-DC converter), power from a power bus to a first domain, the first domain comprising first one or more circuitries;
- supplying, by a second DC-DC converter, power from the power bus to a second domain, the second domain comprising second one or more circuitries;
- and
- transmitting, by a cross-domain DC-DC converter, power from or to at least one of the first or second domains.
