Abstract
The invention discloses a power management circuit of a multi-core processor. An optional core processor or a core processor group of the multi-core processor can independently select a channel of suitable voltage from multiple channels of voltage outputs provided by a switch power source via a power grid on a chip according to load (idling degree). By means of providing different voltages to the different core processors or core processor groups of the multi-core processor, self power consumption of the multi-core processor is reduced, energy is saved, and duration time of a battery during power supply is prolonged.
Description
Technical field:
The present invention relates to the power management of polycaryon processor, is a kind of electric power management circuit, specifically, is a kind of polycaryon processor electric power management circuit.
Background technology:
High-performance processor just develops rapidly towards the direction of multinuclear.Double-core, four nuclears, 16 nuclears, 64 nuclears, the check figure of processor constantly increases on single chips.Use for the overwhelming majority, computing machine there is no need to make processors all on the chip all to be in the maximal workload state.Under the low workload state and under the off position, processor can adopt the method that reduces its power supply input voltage to reduce power consumption.At present, on the polycaryon processor chip, all processor cores are shared same power supply input, and this makes arbitrary this processor of nuclear can't select its power supply input voltage independently, and all processors all must be in under a kind of electric source modes.The present invention proposes a kind of novel polycaryon processor power management scheme, makes arbitrary this processor of nuclear can select its power supply input voltage independently, and according to the main system needs, it can get into more energy-conservation state rapidly.
Summary of the invention:
The electric power management circuit that the purpose of this invention is to provide a kind of polycaryon processor.Any core processor or core processor crowd can be through the supply networks on the chip, the independent voltage that selection one tunnel is suitable for from the plurality of voltages output that Switching Power Supply provides.
Technical solution of the present invention is:
A kind of polycaryon processor electric power management circuit is characterized in that: any core processor of polycaryon processor or core processor crowd can select one the tunnel to be suitable for voltage from the plurality of voltages output that Switching Power Supply provides through the electrical network on the chip is independent.
There are one or more Switching Power Supplies that the output of the different voltages of several is provided in the electric power management circuit, give each core processor nuclear (crowd) through the supply network on the chip.Each core processor (crowd) all is connected to several various power lines, can independently select power taking from any one or more supply lines.
Each core processor or each processor crowd are connected on the various power line through several switches, connect a power transistor that switch can be one or more parallel connections of a processor core (crowd) and a supply lines.The switch that connects a core processor or a processor crowd and many supply lines can use logical drive exclusively, and guaranteeing can be by the mistake short circuit between wantonly two supply lines.
The transistor that connects a core processor or a processor crowd and arbitrary supply lines also can use analog drive circuit to drive, and regulates transistorized electric conductivity value.This analog drive circuit can be one or several amplifier.Analog drive circuit uses processor required voltage and alternative supply voltage as input, and the driving power transistor is realized linear voltage decreasing.Under this implementation, Switching Power Supply only need provide a spot of several voltage output (thick accurate the adjusting), and the voltage that the linear voltage decreasing of power transistor allows each core processor (or processor crowd) to be got has more trickle adjusting (thin accurate the adjusting).
In the past, though different processor has different needs on the polycaryon processor, power-supply management system all only provides an identical voltage.The present invention provides different voltages with different through core processors different in polycaryon processor or core processor crowd, has reduced the oneself power consumption of polycaryon processor, energy savings, the cruising time when having prolonged powered battery.
The method for managing power supply of contrast patent documentation: CN 200510102506.4 CPU, the method and apparatus that CN201010248261.7 central processing unit duty and sleep state switch.
