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.
At present, in a chip design scheme for low-power wake-up, only a few fixed pins are available for chip pins capable of supporting wake-up in a low-power mode, which greatly limits the manufacturing of a system circuit board and reduces the flexibility of application.
In view of this, embodiments of the present application provide a low power consumption wake-up method and apparatus, where in a low power consumption mode, an input signal in a chip pin is configured, the input signal is detected, and when a level of the input signal is detected to change, an interrupt wake-up signal is output to wake up the chip, so that all input and output pins of the chip have a low power consumption wake-up function, thereby improving flexibility of chip application.
It is to be understood that the terms "first," "second," and the like in the following description are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.
Fig. 1 is a flowchart of a low power consumption wake-up method according to an embodiment of the present application, where an execution subject of the method shown in fig. 1 may be a low power consumption wake-up apparatus, and referring to fig. 1, the method includes:
s101: in a low power mode of the chip, the input signals in the chip pins are configured.
S102: and carrying out signal detection on the input signal.
S103: when the level of the input signal changes, an interrupt awakening signal is output to awaken the chip.
Specifically, configuring the input signal in the chip pin may include: the method comprises the steps of grouping pins of the chips, configuring input signals in the pins of each group of chips by using an input selector or a logic arithmetic unit aiming at the pins of each group of chips, and grouping the pins of the chips to enable more interrupt sources to be output and achieve the effect of improving the accuracy of the positioning awakening source.
The steps involved will be described in detail below with reference to fig. 2, as shown in fig. 2. Wherein, the IO wake-up module may include: IO source selection circuit, detection circuit and register circuit.
In fig. 2, the functions of the parts are as follows:
IO (Input and Output): the input/output pins on a chip, usually divided by groups, such as 64pin chips, may be divided into 4 groups of IOs, each group of IOs having 16.
An IO wake-up module: the method mainly comprises the steps of selecting an IO input source, detecting edge change of an input signal, and triggering interruption to a CPU and a PC module.
CPU (central processing Unit ): the chip is used for processing instructions and data, controlling other peripheral devices and the like and is a core component of the chip.
NVIC (Nest Vector Interrupt Controller): the portion of the CPU responsible for interrupt processing.
PC (Power Controller): the power management system in the chip is mainly responsible for the functions of regional power off and power on.
RCC (Reset and Clock Controller ): and the control chip is responsible for controlling clocks and reset signals of all peripheral equipment in the chip.
An edge detection circuit: edge variations of the input signal are detected, optionally rising edge detection or falling edge detection or both.
IO Source select register (0-M): the IO inputs of each group are selected, one of which may be selected, or all of which may be entered simultaneously.
PES (Peripheral Event System, Peripheral Event management System): mainly detects the edge change of input signals and triggers the interrupt to CPU and PC module.
In the embodiment of the application, the chip pins can be divided into M groups of ports, namely port0 and port1 … port M, and each group of IO ports has N IOs.
The flowchart of the method shown in fig. 1 is described with reference to the block diagram shown in fig. 2, which specifically includes the following steps: in the low power consumption mode, the IO source selection circuit is used to select an input signal for a pin of the chip, and may select one pin or multiple pins, which is not limited in this embodiment of the application.
The output of the IO source selection circuit is an input signal to be detected, the input signal is input into the signal detection circuit, the selected input signal is subjected to signal detection, and after passing through the signal detection circuit, an interrupt wake-up signal can be output.
It should be noted that how to power up the system after outputting the interrupt wake-up signal will not be described in detail below.
It should be understood that the signal detection circuit in fig. 2 is an edge detection circuit, and may also be another signal detection circuit, which is not limited in this embodiment of the present application.
The interrupt wakeup signal in fig. 2 is stored in the RS flip-flop or in a register, as shown in fig. 3.
It should be noted that the block diagrams shown in fig. 2 and fig. 3 are only different in the location where the wake-up signal is stored, and therefore, redundant description of fig. 3 is not repeated herein.
Further, in the embodiment of the present application, the input signal in the pin of each group of chips may be stored in a first register, and the interrupt wakeup signal may be stored in a second register.
It should be noted that the first register is a register in the IO source selection circuit, and the second register is a register saved by an interrupt wakeup signal output by the signal detection circuit after that.
It can be understood that after the chips are grouped, each group can output an interrupt wake-up signal because each group only has one signal detection circuit.
Specifically, after the chips are grouped, all the IO in Port1 may be connected to an IO selection module, and the output of the IO selection module is connected to an edge detection module. Port2 is connected to Port N in the same manner as Port 1.
Referring to fig. 4, which IO or ones of the IO in the multiplexer or the or logic operator are configured as input, and then whether the input of the signal detection circuit is from the output of the multiplexer or the output of the or logic is selected through the alternative input selector.
It will be appreciated that the inputs selected by the multiplexers or the inputs of the or logic configuration may be stored in the IO source selection registers, and the inputs ultimately selected by the alternative selector may also be stored in the IO source selection registers.
Before the CPU enters a sleep state or a power-off state, the configuration of the selection of the input signals needs to be carried out, after the CPU enters the sleep state or the power-off state, the level change of the selected IO input signals is always detected by a signal detection circuit, when the level change of the IO input signals is detected, a wake-up signal is output, the wake-up signal can be locked in a register, meanwhile, the wake-up signal can send out an interrupt through the OR logic of an IO wake-up module, one side of the interrupt is transmitted to the CPU, and the other side of the interrupt is transmitted to a PC module, so that the chip can be woken up.
If the CPU is in a power-off state at the moment, the PC module can normally supply power to the chip after receiving the wake-up signal, the CPU and the peripheral start to work, the RCC starts to recover a clock and a reset signal of the chip after receiving the power supply, the CPU processes the interrupt sent by the IO wake-up module after recovering the normal power supply and the clock, a corresponding set of IO wake-up mark signals can be found in an IO wake-up module register, and then the level of which pin is changed is judged according to the configuration of the IO source selection register.
If the CPU is in a sleep state at this time, after receiving the interrupt sent by the IO wakeup, the CPU can directly work to process the interrupt sent by the IO wakeup, can find the corresponding group of IO wakeup mark signals in the IO wakeup module register, and judges which pin has the level change according to the configuration of the IO source selection register.
In the embodiments of the present application, it can be understood that: and determining the chip pin with the level change by using the interrupt wake-up signal stored in the second register and the input signal stored in the pin of each group of chips stored in the first register.
To sum up, the embodiment of the present application can firstly group the pins of the chip, which is divided into ports 0, ports 1 are up to ports, the number of specific pins in each group can be any value, then each group of pins is connected to the IO source selection circuit, one or more pins can be selected in the selection circuit as input signals, the output signals of the IO source selection circuit are input into the detection circuit for detection, when the input signals have level change, the detection circuit outputs wake-up signals to wake-up the system, the wake-up signals can be latched through the register, after the system is woken up, the CPU can position specific wake-up pins according to the configuration of the register in the IO source selection circuit and the wake-up information latched by the register.
