Detailed Description
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
users often start functions of an internet of things (IoT) chip, such as a WIFI function, a bluetooth function, and the like, but actually there is no actual data transmission, and in this state, it is very important to reduce power consumption of the internet of things (IoT) chip, and simultaneously achieve the purpose of keeping the system always on line or connecting to a network. For example, it is important to reduce power consumption when WIFI is turned on, and to keep the system always on-line with WIFI. The embodiment of the invention discloses a method for reducing chip power consumption, which comprises the following steps,
An internet of things (IoT) chip keeps a system always on line or is connected to a network, a certain connection keeping frame needs to be sent in a fixed period of X ms, the duration of the connection keeping frame is defined as Y ms, and the IoT chip can enter a sleep state within the time of (X-Y) ms without data transceiving. A counter working in a 32K clock domain is arranged inside an Internet of things (IoT) chip, when the chip sleeps, only a TIMER working in the IoT chip works, and a TIMER counting clock is 32KHz at a slow speed. Before an internet of things (IoT) module in the IoT chip prepares to transmit or receive a next period keep connection frame, the IoT chip wakes up the whole chip in advance through timing of TIMER and powers on other modules, so that the IoT module of the IoT chip can normally receive the keep connection frame. Therefore, the power consumption of an internet of things (IoT) chip can be greatly reduced under the condition that the system is always on line or connected with a network.
And the Internet of things (IoT) chip receives the next period of connection maintaining frame, decides to sleep or wake up next time according to the frame information, and if the Internet of things (IoT) chip wakes up, the Internet of things (IoT) chip may also need to wake up the application processor AP chip or the microcontroller MCU chip. When an application processor AP chip or a microcontroller MCU chip is needed by an Internet of things chip, a microprocessor in the Internet of things (IoT) chip sets an IOT _ WAKEUP signal to be at a high level, when the application processor AP chip or the microcontroller MCU chip receives the IOT _ WAKEUP signal, the application processor AP chip or the microcontroller MCU chip enters an internal awakening flow of the application processor AP chip or the microcontroller MCU chip and enters a working state, and then the application processor AP chip or the microcontroller MCU chip sets the IOT _ WACK signal to be at the high level. When an internet of things (IoT) chip receives the IoT _ wake, knowing that the application processor AP chip or the microcontroller MCU chip has woken up, the IoT _ wake signal is set to a low level. The application processor AP chip or the microcontroller MCU chip and the internet of things (IoT) chip may both enter a sleep mode to reduce power consumption. The specific flow and interaction is shown in fig. 1. Fig. 1 is a method for interaction between an AP chip or a MCU chip of a microcontroller and an internet of things (IoT) chip according to the present invention.
accordingly, in order to implement the interaction flow in fig. 1, three working states are set inside an internet of things (IoT) SOC chip.
OFF, this is the Internet of things (IoT) chip power-on default state. The power supply of most modules of an internet of things (IoT) chip is closed, and only an IO pin module and a Power Management Unit (PMU) supply power.
Working is the normal working mode of an Internet of things (IoT) chip. When the internet of things (IoT) chip carries out data transmission, the IoT chip is in a normal working mode.
SLEEP internet of things (IoT) chip SLEEP mode. When an internet of things (IoT) chip has no data transmission within a set time, the sleep module is entered. And the MCU inside the Internet of things (IoT) chip enters standby, and other functional modules are in a low-power-consumption mode and can be powered off. The Timer module operates.
the three states and transition conditions are shown in figure 2. Fig. 2 is a diagram of an internet of things (IoT) chip internal state machine and state condition transition.
in some application scenarios, an internet of things (IoT) chip works independently, an application processor AP chip or a microcontroller MCU chip is not provided at the periphery of the system, and at this time, input signals IoT _ ONOFF and IoT _ WACK may be connected to a high level, and the internet of things (IoT) chip works independently. In this case, the internet of things (IoT) chip will transition in the WORK and SLEEP states.
Correspondingly, different power domains are arranged in an Internet of things (IoT) chip to achieve the aim of reducing power consumption by turning off the power supplies of the different power domains under different states.
in the power domain division in the Internet of things (IoT) chip, in the IoT chip, under the default state, the power supply of most modules is closed, and only an IO pin module and a power management unit PMU supply power. When IOT _ ONOFF is high, the power and clock management unit wakes up the chip, turns on switch 1, i.e. the MCU block switch,
at this moment, the MCU (micro control processor unit) inside the Internet of things (IoT) chip supplies power, after the MCU supplies power, the MCU receives the IOT _ ONOFF interruption and exits from the standby state, the MCU module instructs the power management unit PMU to start the switch 2 and the switch 3, namely the IoT module switch and the timer switch, and at this moment, all modules inside the chip supply power. And opening the function of the chip of the Internet of things.
When a user needs to close the function of an internet of things (IoT) chip, the application processor AP chip or the microcontroller MCU chip sets the IOT _ ONOFF to be a low level, and the function of the IoT chip is closed. The method comprises the following specific steps: inside thing networking (IoT) chip, MCU receives the interrupt that IOT _ ONOFF set to low level, and the MCU module instructs power management unit PMU to close switch 2, switch 3, closes the power supply of other inside chips. MCU gets into the standby state, and power management unit PMU detects that MCU gets into the standby state, and other conditions satisfy, and power management unit PMU closes MCU switch 1, and the chip gets into the OFF state.
correspondingly, a set of module power on and off processes is provided for independently controlling the power supplies of the modules (e.g., the power switches 1, 2, 3 described above). The method comprises the following specific steps:
When an Internet of things (IoT) chip needs a certain power domain to work, the starting process of the independent power supply of the module is started, and the corresponding module can work normally after finishing the power supply starting.
when the Internet of things (IoT) chip does not need a certain module to work, the power-off process of the module independent power supply can be started, and the module can be powered off, so that the standby power consumption of the chip is reduced.
the method for reducing the power consumption of the chip provided by the invention is described in detail above, a specific example is applied in the text to explain the principle and the implementation of the invention, and the description of the above example is only used to help understanding the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
