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.
Generally, many failure phenomena of the memory controller are directly related to a power supply system of the circuit board, such as the memory controller cannot be normally started, the memory controller is repeatedly restarted, and the like; recording the power-up and power-down times of the memory controller clearly provides important information for locating such problems. However, a method of recording the time when the memory controller is repeatedly restarted or powered up and down for many times has not been developed. In the recording device for the power-on and power-off moments of the storage controller, the control module determines the target storage area of the power-on according to the zone bit values, the zone bit values are preset in the zone bit value range, the zone bit value range comprises two or more zone bit values, and at least two target storage areas exist in the corresponding storage module and are used for storing the power-on and power-off moments.
The embodiment of the invention discloses a recording device for storing power-on and power-off moments of a controller, which is shown in figure 1 and comprises: a control module 1, a storage module 2 and an RTC (Real Time Clock) module 3, where the control module 1 is configured to execute the following steps:
when the memory controller is powered on, reading the zone bit value of the zone bit in the memory module 2;
judging whether the value of the flag bit is within a preset flag value range or not; if not, setting the flag bit value as the lower limit value of the preset flag value range;
the current time is acquired through the RTC module 3 and written into a power-on time storage unit and a power-off time storage unit of a target storage area; the target storage area is a storage area corresponding to the flag bit value in the storage module 2;
adding 1 to the numerical value of the zone bit and storing the zone bit again to determine a corresponding target storage zone when the storage controller is powered on next time;
and after waiting for a preset time period, updating the recording time in the power-off time storage unit corresponding to the power-on.
It can be understood that the number of the preset flag values in the preset flag value range corresponds to the number of the storage areas, each storage area includes a power-on time storage unit and a power-off time storage unit, and corresponds to the number of the latest power-on times and the latest power-off times that can be recorded by the recording device. The processing of the current zone bit value in the zone bit is actually adjusting the corresponding target storage zone, for example, adding 1 to the zone bit value and storing the value into the zone bit again, so as to determine the target storage zone corresponding to the next power-on of the storage controller, for example, reading and judging whether the zone bit value is within the range of the preset zone bit value as soon as the storage controller is powered on, because the operation of adding 1 to the zone bit value at the last power-on may make the zone bit value at the current power-on larger than the range of the preset zone bit value, and once this occurs, the zone bit value needs to be corrected and set as the lower limit value of the range of the preset zone bit value.
Taking the preset flag value range as n being 1, 2, and 3 as an example, three corresponding storage areas exist in the storage module 2 for recording power-on and power-off times, specifically:
if the storage controller is powered on at this time, and the current zone bit value is 2, directly taking the 2 nd storage area as a target storage area, recording and updating time in a power-on time storage unit and a power-off time storage unit, adding 1 to the zone bit value and storing the zone bit again, and determining that the target storage area corresponding to the next power-on of the storage controller is the 3 rd storage area;
if the storage controller is powered on this time, the current zone bit value of the zone bit in the storage module 2 is read to be 4, because the zone bit value is the upper limit value 3 of the range of the preset zone value when the storage controller is powered on last time, the zone bit value is directly added with 1 after the storage controller is powered on last time and then written into the zone bit, the zone bit value directly obtained by the power on this time is not in the range of the preset zone value, and at this time, the storage module 2 does not have a corresponding storage zone, so that the zone bit value is set to be the lower limit value 1 of the range of the preset zone bit, and the storage zone of the 1 st block corresponding to the storage module 2 is a target storage.
It can be seen that the power-up and power-down time of the memory module 2 in this embodiment is continuously updated, but because the number of the memory areas is limited, the power-up and power-down time of the last power-up times can only be recorded, the number of times is consistent with the number of the memory areas, and once the number of times is exceeded, the earliest power-up and power-down time record is overwritten to write the latest power-up record.
It can be understood that the preset flag value range includes a plurality of integers, the number of the integers corresponds to the number of the most recent power-on records that can be recorded by the recording apparatus, and for the consideration of convenience and convenience of programming, the preset flag value range generally includes a plurality of continuous natural numbers starting from 1, but may also include other sequence numbers, such as a sequence number sequence with a starting point different from 1, or a sequence number sequence with discontinuous intervals, at this time, an action of adding 1 to the flag bit value needs to be correspondingly adjusted, and the action purpose is not changed, and after the target storage area of the power-on of this time is determined according to the current flag bit value, the current flag bit value is changed to determine the target storage area of the power-on of the next time, but the value of the specific preset flag value range may be set according to actual requirements.
Further, the power-on time and the power-off time within the power-on time period of each power-on of the memory controller are respectively recorded in the power-on time storage unit and the power-off time storage unit of the target storage area, because the power-off time is unpredictable, the current time is simultaneously counted into the power-on time storage unit and the power-off time storage unit through the RTC module 3 during actual recording, the current time is the power-on time, then the recording time of the power-off time storage unit is updated after waiting for a preset time period each time, and once the storage controller is powered off, the control module 1 stops updating the recording time of the power-off time storage module, so that the recording time in the power-off time storage module is the last update during power-on, that is, the power-off time of the storage controller, and the error between the power-off time and the actual power-off time does not exceed a preset time period. The preset time period may be set to 1 minute or other values, and the smaller the preset time period is, the faster the update frequency is, the smaller the error between the recording time and the actual time is, and the larger the resource power consumption is, so that the value of the preset time period needs to be balanced between the frequency and the power consumption.
Generally, when the power-off time storage unit is updated, a new recording time can be acquired by the RTC module 3 and then written into the power-off time storage unit by the control module 1, or a new recording time can be obtained by directly adding a preset time period to the original recording time by the control module 1 and written into the power-off time storage unit, and waiting for the preset time period in the execution process can be realized by the RTC module 3, or by a timer inside the control module 1.
That is, after waiting for a preset time period, the process of updating the recording time in the power-off time storage unit may specifically include: after waiting for a preset time period, the current time is acquired through the RTC module 3, and the current time is written into the power-off time storage unit.
Or, after waiting for a preset time period, the process of updating the recording time in the power-off time storage unit may specifically include: and after waiting for a preset time period, reading the recording time in the power-off time storage unit, and writing the sum of the recording time and the preset time period into the power-off time storage unit.
At this time, the process of acquiring the current time by the RTC module 3 further includes: starting a timer, wherein the timing time is a preset time period;
correspondingly, after waiting for a preset time period, the process of updating the recording time in the power-off time storage unit comprises the following steps:
and when the timer reaches a preset time period, updating the recording time in the power-off time storage unit.
When the modules of each part are selected, the control module 1 may be a CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gate Array), and the storage module 2 is an EEPROM (Electrically Erasable Programmable read only memory). Further, the storage module 2 and the control module 1 are connected via an I2C (Inter-Integrated Circuit) communication interface, and the control module 1 and the RTC module 3 are connected via an I2C communication interface. In addition to these options, other approaches to achieve the effects of the recording apparatus in the present embodiment are also within the scope of the present embodiment.
It will be appreciated that in order to avoid the power supply of the storage controller affecting the power supply of the recording apparatus, a separate power supply or a backup power supply such as a button cell may be provided, and therefore the recording apparatus further comprises: the power module is used for supplying power to the control module 1, the storage module 2 and the RTC module 3, or the recording device further comprises: and the standby power supply is used for supplying power to the RTC module 3 after the onboard power supply is powered off.
