Detailed ways

FIG. 1 is a block diagram of a temperature detection control circuit provided by an embodiment of the present disclosure.

Referring to Figure 1, the temperature detection control circuit provided by the embodiment of the present disclosure includes: a first signal module 101 configured to generate an enable signal TSEn0 in response to the power-on signal Poweron, where the enable signal is a pulse signal; a mode control module 102, It is configured to receive the test signal TmTSProbe, perform segmented transmission of the enable signal TSEn0, output the enable signal TSEn0 during the period when the test signal TmTSProbe is invalid, and use the enable signal TSEn0 as the first enable signal TSEn, and output during the period when the test signal TmTSProbe is valid. Enable signal TSEn0 and use enable signal TSEn0 as the second enable signal TmTSEn; wherein, the test signal TmTSProbe is valid in the test mode, and the test signal TmTSProbe is invalid in the working mode; the second signal module 103 is configured to receive the second enable signal TmTSEn. An enable signal TSEn, a second enable signal TmTSEn and a temperature measurement end signal TSDone. The temperature measurement enable signal TSCoreEn is generated based on the first enable signal TSEn and the temperature measurement end signal TSDone. Based on the second enable signal TmTSEn and the temperature measurement end signal TSDone, the temperature measurement enable signal TSCoreEn is generated. The end signal TSDone generates the temperature measurement enable signal TSCoreEn, and the temperature measurement enable signal TSCoreEn is used to control the temperature detection module for temperature detection.

In the above technical solution, the first signal module 101 generates the enable signal TSEn0 after receiving the power-on signal Poweron; the mode control module 102 receives the enable signal TSEn0 and the test signal TmTSProbe, and indicates that it is in the working mode during the period when the test signal TmTSProbe is invalid. , then the mode control module 102 receives the enable signal TSEn0 and uses the enable signal TSEn0 corresponding to the period when the test signal TmTSProbe is invalid as the first enable signal TSEn. During the period when the test signal TmTSProbe is valid, it indicates that it is in the test mode, then the mode control module 102 receives The enable signal TSEn0 and the enable signal TSEn0 corresponding to the valid period of the test signal TmTSProbe are used as the second enable signal TmTSEn. In this way, the mode control module 102 can generate the first enable signal TSEn corresponding to the working mode and the corresponding test mode. the second enable signal; in the working mode, the second signal generation module 103 receives the first enable signal TSEn to generate the temperature measurement enable signal TSCoreEn; in the test mode, the second signal generation module 103 receives the second enable signal TmTSEn generates the temperature measurement enable signal TSCoreEn, thereby realizing the generation of the test enable signal using different enable signals in different modes, and avoiding the signal noise of the corresponding enable signal under the operating conditions of one mode from affecting the operation of the other mode. That is to say, the noise that occurs during the operation of one of the first enable signal or the second enable signal is prevented from affecting the effective operation of the other one.

In addition, the first enable signal TSEn corresponding to the working mode and the second enable signal TmTSEn corresponding to the test mode both come from the enable signal TSEn0 generated by the first signal module 101. That is to say, the first enable signal TSEn corresponding to the working mode and the second enable signal TmTSEn corresponding to the test mode can be used. The enable signal TSEn0 generated by the signal module 101 is used to generate the first enable signal and the second enable signal that are valid in different periods, which is beneficial to reducing circuit complexity and saving power consumption of the temperature detection control circuit.

The temperature detection control circuit provided by the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

In some embodiments, the temperature detection control circuit may be applied to temperature detection of the storage device. When the first signal module 101 receives the power-on signal Poweron, it indicates that the temperature detection control circuit needs to enable the temperature detection control function and needs to generate the temperature measurement enable signal TSCoreEn for controlling temperature detection.

Figure 2 is a block diagram of the first signal module in the temperature detection control circuit provided by an embodiment of the present disclosure. Figure 3 is a schematic circuit structure diagram of the first signal module in the temperature detection control circuit provided by an embodiment of the present disclosure. Figure 4 The signal timing diagram of each signal in the first signal module 101 is provided for the embodiment of the present disclosure.

Referring to Figure 2, in some embodiments, the first signal module 101 may include: an oscillation circuit 111 configured to generate an oscillation signal OSC in response to the power-on signal Poweron; an enable signal generation circuit 121 configured to receive the oscillation signal OSC, and based on the number of oscillations of the oscillation signal OSC, an enable signal TSEn0 is generated.

The power-on signal Poweron is a high-level signal, that is, the power-on signal Poweron is a logic "1" level, and the oscillation circuit 111 starts to oscillate. It can be understood that in some embodiments, the power-on signal Poweron can be transmitted not only to the first signal module 101 but also to the storage array of the storage device, indicating that the storage array is powered on to enter the working state.

The oscillation circuit 111 is used to generate a periodically changing voltage signal, that is, an oscillation signal OSC. The oscillation circuit 111 may be a sine wave oscillator or a non-sinusoidal wave oscillator. The waveform generated by a sine wave oscillator is very close to a sine wave or cosine wave, and the oscillation frequency is relatively stable; the waveform generated by a non-sinusoidal oscillator is a non-sinusoidal pulse waveform, such as square waves, rectangular waves, sawtooth waves, etc. Non-sinusoidal oscillators do not have high frequency stability. Correspondingly, the oscillation signal OSC can be a sine wave or a cosine wave, and the oscillation signal OSC can also be a square wave, rectangular wave or sawtooth wave. Depending on the specific circuit structure of the oscillation circuit 111, the oscillation signal OSC may have different waveforms.

Referring to Figure 3, in some embodiments, the oscillation circuit 111 may be an RC delay based Ring oscillator, including: a NAND gate AN, an input end of the NAND gate AN receives a power-on signal; a cascade connection At least two resistors R and at least two inverters inv, the first resistor R is connected to the output end of the NAND gate AN, and the last resistor is connected to the other end of the NAND gate AN via an inverter inv. , and two resistors R of adjacent stages are connected through an inverter inv; there are at least two capacitors C, one end of the capacitor C is connected to the connection node between the resistor R and the input end of the inverter inv, and the other end is connected to the ground. It should be noted that FIG. 3 only illustrates two resistors R, two inverters inv and two capacitors C. In fact, the oscillation circuit 111 may include N resistors R, N inverters inv and N A capacitor C, N can be any even number greater than or equal to 2, such as 4, 6, 8, etc.

In other examples, the oscillation circuit 111 may also be an LC oscillator or a quartz crystal oscillator.

The oscillation signal OSC is transmitted to the enable signal generation circuit 121, and the enable signal generation circuit 121 obtains the oscillation period of the oscillation signal OSC, and when the oscillation period reaches the preset period, a pulse is generated; after that, the enable signal generation circuit 121 obtains The oscillation period is reset to zero and the oscillation period is reacquired. When the reacquired oscillation period reaches the preset period, the next pulse is generated; in this cycle, multiple pulses are generated to continuously form the enable signal TSEn0.

Continuing to refer to FIG. 3 , in some embodiments, the enable signal generation circuit 121 may include: a counter 11 configured to receive the oscillation signal OSC and count the number of oscillations of the oscillation signal OSC, and obtain a count value B<n:0 >, and the count value B<n:0> is reset to zero and the number of oscillations of the oscillation signal OSC is counted again; the pulse generation unit 12 is configured to receive the count value B<n:0>, and when the count value B< When n:0> reaches the preset value, the enable signal TSEn0 is generated, and the count value B<n:0> of the counter 11 is controlled to return to zero.

The counter 11 obtains the number of oscillation cycles of the oscillation circuit 111 by counting the number of oscillations. It can be understood that the count value B<n:0> represents the number of cycles of the oscillation cycle. The count value B<n:0> serves as an external trigger signal for the trigger pulse generation unit 12 to generate the enable signal TSEn0. When the count value B<n:0> reaches the preset value, the pulse generation unit 12 generates a pulse of the enable signal TSEn0. , and after the count value B<n:0> of the counter 11 is reset to zero, the oscillation signal of the oscillation signal OSC is counted again, and a new count value B<n:0> is generated; at the new count value B<n:0 >When the preset value is reached, the pulse generation unit 12 generates the next pulse of the enable signal TSEn0. By repeating this cycle, the pulse generation unit 12 generates the required enable signal TSEn0. Specifically, the pulse generation unit 12 may also be configured such that if the pulse generation unit 12 generates a pulse of the enable signal TSEn0, it also generates a first reset signal CntRst, and the counter 11 responds to the first reset signal CntRst for the count value B< n:0>reset to zero.

It can be understood that the count value B<n:0> represents the number of oscillation cycles, and the duration of a single oscillation cycle of the oscillation circuit 111 can be known, and the corresponding count value B<n:0> can also represent the oscillation duration, The preset value also represents the preset duration. When the count value B<n:0> reaches the preset value, it indicates that the oscillation duration meets the preset duration. The pulse generation unit 12 generates a pulse of the enable signal TSEn0.

The counter 11 may be a flip-flop based counting circuit. In a specific example, the counter 11 can be a 16-bit counter, and n in the corresponding count value B<n:0> is 15. It can be understood that the number of bits of the counter 11 can be determined according to actual needs. The counter 11 has a maximum count value, and the maximum count value represents the maximum oscillation duration, as long as the maximum oscillation duration represented by the maximum count value of the counter 11 is less than or equal to the predetermined value. Just set the default duration of the representation. For example, the counter 11 may be a 4-bit counter, an 8-bit counter, or a 32-bit counter.

In addition, the counter 11 has a reset terminal, and the reset terminal of the counter 11 is also activated by receiving the power-on signal Poweron.

Continuing to refer to FIG. 3 , in some embodiments, the pulse generation unit 12 may include: a decoding unit 1201 configured to receive the count value B<n:0>, and when the count value B<n:0> reaches the preset value A decoded signal is generated when The first reset signal CntRst is used to control the count value B<n:0> of the counter 11 to return to zero.

Specifically, when the count value B<n:0> reaches the preset value, the decoding unit 1201 generates a pulse of the decoded signal. In a specific example, the pulse of the decoded signal generated by the decoding unit 1201 may be a high-level pulse, The decoded signal has rising and falling edges. The output unit 1202 may be triggered by the rising edge of the decoded signal to generate a pulse of the enable signal TSEn0. In a specific example, the pulse of the enable signal TSEn0 generated by the output unit 1202 may be a high-level pulse. It can be understood that the output unit 1202 can also be triggered by the falling edge of the level of the decoded signal to generate a pulse of the enable signal TSEn0. After receiving the first reset signal CntRst, the counter 11 resets the count value B<n:0> to zero in order to re-count, thereby causing the decoding unit 1201 to generate the next pulse of the decoding signal, and the output unit 1202 outputs the enable signal TSEn0 Next pulse.

Referring to Figure 3 and Figure 4 in conjunction, in some embodiments, the time interval between receiving the power-on signal Poweron and generating the first pulse of the enable signal TSEn0 is the first interval t1, and the enable signal TSEn0 The time interval between the remaining pulses is the second interval t2, and the first interval t1 may be smaller than the second interval t2. Correspondingly, the preset value may include a first preset value and a second preset value, and the first preset value is smaller than the second preset value; the decoding unit 1201 may include; a first decoding unit 21 configured to receive Count value B<n:0>, and when the count value B<n:0> reaches the first preset value, the first decoding signal En1ms is generated. The first decoding signal En1ms is used to control the first pulse of the enable signal TSEn0. Generate; the second decoding unit 22 is configured to receive the count value B<n:0>, and generate the second decoding signal En32ms when the count value B<n:0> reaches the second preset value, the second decoding signal used to control the generation of remaining pulses of the enable signal TSEn0; the output unit 1202 is also configured to, in response to the first pulse of the enable signal TSEn0, generate a shutdown signal En1msDis, and the shutdown signal En1msDis controls the first decoding unit 21 to stop working. .

The output unit 1202 receives the first decoded signal En1ms and generates the first pulse of the enable signal TSEn0; the output unit 1202 receives the second decoded signal En32ms and generates the remaining pulses of the enable signal TSEn0.

In a specific example, the first interval t1 may be 1 ms, and the second interval t2 may be 32 ms. It can be understood that in other embodiments, the first interval t1 may also be the same as the second interval t2, or the time interval between adjacent pulses, that is, the second time interval, may also have multiple different parameters. The decoding unit 1201 is configured with corresponding multiple sub-decoding units that generate different decoding signals, and this can be achieved if the preset values corresponding to each sub-decoding unit are different, that is, each sub-decoding unit generates corresponding decoding when counting reaches different preset values. signal, correspondingly, the output unit controls at least one of the plurality of sub-decoding units to turn on based on a preset program, for example, according to the number of received pulse signals. It can be understood that since the sub-decoding unit corresponding to the smaller preset value will shield the sub-decoding unit corresponding to the larger preset value, therefore, controlling at least one sub-decoding unit among the multiple sub-decoding units to turn on essentially means that the output unit needs to To close other sub-decoding units whose preset values are less than the target preset value, or at least other sub-decoding units whose preset values are greater than the target preset value, you can judge whether to turn it on based on actual needs, such as current conditions; it should be further explained that, in actual The order in which the sub-decoding units that output decoded signals are turned on may have nothing to do with their corresponding preset values, that is, the time intervals of the enable signal TSEn0 are not necessarily from large to small.

With reference to Figure 3 and Figure 4, after receiving the power-on signal Poweron, that is, the power-on signal Poweron is a high-level signal, the oscillation circuit 111 generates a periodic oscillation signal OSC; the counter 11 starts counting, with the counter 11 as a 16-bit Counter, the first preset value corresponding to the first count value B<15:0> indicates that the oscillation duration is 1ms, and the second preset value corresponding to the second and subsequent count values B<15:0> indicates the oscillation. The duration is 32ms as an example; when the first count value B<15:0> reaches the first preset value, a pulse of the first decoding signal En1ms is generated; when the first count value B<15:0> reaches the first preset value When the second preset value is reached, a pulse of 32ms of the second decoding signal En is generated. The output unit 1202 generates the first pulse of the enable signal TSEn0 in response to the first decoding signal En1ms, generates the turn-off signal En1msDis after generating the first pulse of TSEn0, and generates the enable signal En32ms in response to the second decoding signal En32ms. For the remaining pulses, the first reset signal CntRst is generated during the pulse period when the enable signal TSEn0 is generated. At this time, the count value B<15:0> of the counter 11 is reset to zero.

Referring to Figure 1, the mode control module 102 has a first node net1 and a second node net2. In the working mode, the enable signal TSEn0 is output through the first node net1, and the enable signal TSEn0 output by the first node net1 is used as the first enable signal. enable signal TSEn; in the test mode, the enable signal is output through the second node net2, and the enable signal TSEn0 output by the second node net2 is used as the second enable signal TmTSEn.

Specifically, in the working mode, the mode control module 102 can cut off the transmission path of the enable signal TSEn0 to the second node net2, or the mode control module 102 can have the function of lowering the potential of the second node net2, so that the second node net2 The output enable signal TSEn0 directly changes to a low level signal, which is an invalid enable signal TSEn0. In the test mode, the mode control module 102 can cut off the transmission path of the enable signal TSEn0 to the first node net1, or the mode control module 102 can have the function of lowering the potential of the first node net1, so that the first node net1 outputs The enable signal TSEn0 directly changes to a low level signal, which is an invalid enable signal TSEn0.
