Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Currently, referring to the schematic diagram of PS State transition shown in fig. 1, in the conventional Power consumption control method of SSD, PS0/1/2/3/4 is Power State command, specifically:

PS 0: a full speed operating condition. PS 1: and reducing the speed of a CPU (central processing unit) and an NFC (nand flash controller) flash controller in a speed reducing operation state. PS2: and the speed reduction operation state further reduces the speed of a CPU (central processing unit) and an NFC (nand flash controller) flash controller. PS3: next to the low power mode, the CPU0 enters a WFI (wait for interrupt) state and turns off the NFC power supply. PS4: in the lowest power consumption mode, hardware for processing power and PMA (physical layer electric sub-layer) of PCIE (high speed serial computer expansion bus) are in a power-on state, and other power-off states. The English description in the figure is as follows:

device IDLE: the SSD is in an idle state, and the host does not issue commands to the SSD.

Host Mode Set: the host machine enables the SSD to switch the power state by issuing an NVME command.

CLKREQ #0- >1 (host-given signal): the host goes the clock request signal from low to high and if this state is PS3, it indicates that PS4 is to be entered.

CLKREQ #1- >0 (host-supplied signal): the host goes the clock request signal from high to low, which if the state is PS4, indicates that PS3 is to be entered.

PERST #0- >1 (signal from host): a global reset signal for PCIE indicates to enter PS3 if the state is PS 4.

The method comprises the following steps: PS0/PS1/PS2 are switched with each other, and the switching is directly configured in a software mode, because the related operations are less, the host has requirements on speed switching, a power-off module is not generally related, and only the clock is reduced.

PS3 because the configuration involved is not too much, and because the operation is low power consumption in software, the nand flash controller and nand particles are normally shut down and other modules are not powered down. The CPU is adopted, the power consumption is reduced in a software mode, and the defects that the power consumption is effectively reduced and the CPU cannot be closed are overcome.

PS4 adopts a single micro-control unit to reduce power consumption, and has obvious power consumption reduction and good benefit.

Based on this, the invention provides a normalization low-power-consumption processing method based on a solid state disk, and particularly integrates a low-power-consumption processing flow similar to PS4 in PS3 into a unified flow, so that the power consumption of PS3 is obviously reduced. Because the PS3 exit time is much lower than that of PS4, the requirement of supporting PS3 to exit quickly is also considered in the normalized low power consumption processing flow.

In one embodiment, as shown in fig. 2, a normalized low power consumption processing based on solid state disk is provided, the method includes:

step 202, acquiring a normalized low-power-consumption processing request based on the solid state disk, and entering a low-power-consumption processing flow if the request comprises a PS3 or PS4 command sent by a host;

step 204, judging whether the acquired command is a PS3 command or a PS4 command;

step 206, if the obtained command is a PS3 command, supporting configurable automatic wake-up or host wake-up;

step 208, if the obtained command is a PS4 command, entering a PS4 low power consumption processing flow, and then entering a wait host wakeup state;

in step 210, in the waiting host wakeup state, when any one command of PS0, PS1 and PS2 sent by the host is received, the low power consumption processing flow is exited.

In this embodiment, a normalized low power consumption processing method based on a solid state disk is provided, and it is considered that, when the PS3 considers that a fast exit is taken into consideration, it is required to ensure that a DDR is in a self-refresh state or an ISRAM is in a retention state, because mapping table information is stored in the PS4, the PS4 needs to be acquired from a nand flash, and thus, the time is long.

Firstly, a normalized low-power consumption processing request based on the solid state disk is obtained, and if the request comprises a PS3 or PS4 command sent by a host, a low-power consumption processing flow is entered. The low power consumption processing flow here is low power consumption processing common to PS3 and PS 4.

Next, it is determined whether the acquired command is a PS3 command or a PS4 command. The PS3 needs to multiplex as much as possible the PS4 low power consumption processing modes. PS4 SSD lowest power consumption, DDR is in power-down state or ISRAM is in shut down state compared to PS 3.5. And (4) wake-up of Host: waking up is typically done by PS 0/1/2.

Time configurable auto-wake or host wake up is supported if the command fetched is the PS3 command. If the acquired command is the PS4 command, the method enters the PS4 low power consumption processing flow and then enters the wait host wakeup state. The PS4 low power consumption processing flow is added to the low power consumption processing common to PS3 and PS 4.

In one embodiment, if the obtained command is the PS4 command, the PS4 low power consumption processing procedure is first entered, and then the step of entering the wait for host wakeup state is entered, specifically, the PS4 low power consumption processing procedure further includes a DDR shutdown procedure and an ISRAM shutdown procedure.

Finally, in the waiting host wake-up state, when any command of PS0, PS1 and PS2 sent by the host is received, the low-power consumption processing flow is exited, and the normal processing command is executed.

In this embodiment, by obtaining a normalized low power consumption processing request based on a solid state disk, if the request includes a PS3 or PS4 command sent by a host, a low power consumption processing flow is entered; judging whether the acquired command is a PS3 command or a PS4 command; support time configurable auto-wake or host wake if the retrieved command is a PS3 command; if the obtained command is a PS4 command, the low-power consumption processing flow of the PS4 is firstly entered, and then the state of waiting for the host to wake up is entered; in the wait for host wakeup state, the low power consumption processing flow exits upon receiving any one of commands of PS0, PS1 and PS2 sent by the host. In the scheme, PS3 is combined into a unified flow by going through a low-power-consumption processing flow similar to PS4, so that the power consumption of PS3 is obviously reduced, and the requirement of supporting the rapid exit of PS3 is also met. The scheme realizes simplification of complexity, is easy to maintain, has high flexibility, high speed and small influence on the read-write performance by normalization low-power consumption processing.

In one embodiment, as shown in fig. 3, a normalized low power consumption processing based on solid state disk is provided, in which if the obtained command is a PS3 command, the step of supporting time-configurable auto-wake or host-wake further comprises:

step 302, setting automatic wake-up time;

step 304, the device will automatically wake up when the set wake-up time is reached;

step 306, entering a waiting host waking state if the automatic waking is not needed;

and 308, in the waiting host awakening state, when any command of PS0, PS1 and PS2 sent by the host is received, exiting the low-power consumption processing flow.

In this embodiment, referring to fig. 4, a complete method for implementing the normalized low power consumption processing state is provided, and implemented steps are as follows:

s1: receiving PS3 or PS4 commands sent by the host.

S2: low power consumption processing is entered, which is low power consumption processing common to PS3 and PS 4.

S3: judging whether the command is a PS3 command, if so, entering a state S4; if PS4, proceed to S5.

S4: supporting automatic awakening or Host awakening, setting automatic awakening time, if the set time is up, automatically awakening device, if the set time is not needed, entering a waiting Host awakening state S6; once there is a Host wake-up command PS0/1/2, then state S7 is entered, where processing of commands is commenced.

S5: the low power consumption processing of PS4 is entered, and the low power consumption processing of PS4, such as DDR shut down or ISRAM shut down, is added on the basis of S2; and then enters a wait-Host awake state S6.

S6: when the Host sends PS0/1/2, the process goes to S7 to start processing the relevant command.

S7: and exiting low power consumption and processing the command normally.

In the embodiment, the proposed method for normalizing low power consumption processing performs power processing on PS1/PS2/PS3/PS4 (PS0 is in full-speed mode, and does not relate to low power consumption), and the SSD power consumption, especially the PS3 power consumption, is significantly improved without affecting the performance. In addition, the design scheme has the advantages of high switching speed, high flexibility, low power consumption and low cost.
