Description

Technical Field

[0001] The present invention relates to the field of electronic circuits and signal processing, and in particular to a sensing-storage-computing integrated macro unit circuit, system and analog-to-digital conversion method. Background Art

[0002] With the development of the industrial Internet, higher requirements are placed on video acquisition and processing technologies. In traditional visual application systems, image sensors collect image information, convert optical signals into electrical signals, and convert them into digital signals after digital-to-analog conversion. The image data is then processed by the image signal processing unit and finally output to the processor in the system through a special video interface. The processor then performs data analysis and makes corresponding controls and operations.

[0003] In applications such as image processing and laser ranging, Figure 1 As shown, the sensing, storage and computing integrated chip realizes efficient and low-power data processing by integrating sensing, storage and computing functions. Among them, in the middle is the processing macro unit (PE) 1 array, which is closely arranged together in the form of an array of PEs, such as a 1024*1024 scale. Because each PE includes a sensing, storage and computing basic unit, all PEs in the PE array can process the data in each unit in parallel at the same time. This method is also often called single instruction multiple data mode, namely SIMD, which is more common in GPUs. Row control modules 5 and column control modules 6 are designed in the horizontal and vertical directions of the PE array respectively. The row control module 5 is used to select rows and perform related control on the PE array. The corresponding column mode control module is used to select columns and perform related control on the PE array, as well as data readout selection. The periphery of the PE array also includes a peripheral digital module 4, an INS bus 41, a peripheral analog module 3, and an interface module 7.

[0004] like Figure 2 As shown, the PE unit includes a sensing unit (SU), an analog signal operator operation unit (AOP), an analog storage unit (AREG Bank), a digital storage unit (DREG bank), a tag module (TAG), and an adjacent PE communication unit (AdjacentIF). The analog storage unit includes several analog signal memories AREG0, AREG1..., and the analog signal memory itself is also an operation unit. Similarly, the digital storage unit includes several digital signal memories DREG0, DREG1..., and the digital signal memory can perform logical operations in addition to storing digital signals. The output of the tag unit is used as a judgment signal to control whether the current PE executes the current SIMD instruction.

[0005] To convert conventional analog signals to digital signals, a special ADC chip or ADC circuit is needed to realize the conversion. For traditional image sensors, from the early single ADC to the column-level ADC, and then to the latest pixel-level ADC design, the chip area and the energy consumption required for conversion will increase, and the pixel-level ADC requires more advanced process technology, such as stacking process. Because of the ADC design size limitation and the ADC frequency characteristic requirements, the traditional data handling process results in high processing delay and high power consumption.

[0006] Especially for the memory and computing chip, the analog memory and computing units and digital memory and computing units in PE face great problems when the signals interact or flow in the analog and digital domains. Either the ADC circuit is designed in PE, but it brings problems of circuit area and power consumption. Or the serial conversion is carried out through a single ADC circuit, which brings efficiency problems, data flow delay and power consumption problems. Summary of the invention

[0083] like Figure 1 As shown, in this embodiment, the sensing-storage-computing integrated macro unit system is specifically designed in a pixel-level sensing-storage-computing integrated chip, with a processing macro unit (PE) array in the middle, which is closely arranged together in the form of an array by PE1, for example, a scale of 1024*1024. The internal structure of PE is described in detail with reference to the specific sensing-storage-computing integrated macro unit circuit and the embodiments of the sensing-storage-computing integrated macro unit circuit later. Here, only the overall architecture of the sensing-storage integrated macro unit system is described.

[0084] Because each PE includes a basic sensing, storage and computing unit, all PEs in the PE array can process the data in each unit in parallel at the same time. This method is also often called single instruction multiple data mode, namely SIMD, which is more common in GPUs. Row control modules and column control modules are designed in the horizontal and vertical directions of the PE array respectively. The row control module is used to perform row selection and related control on the PE array, and the corresponding column mode control module is used to perform column selection and related control on the PE array, as well as data readout selection.

[0085] In one embodiment, the sensing-storage-computing integrated macro unit system includes a plurality of sensing-storage-computing integrated macro unit circuits arranged in an array structure, and specifically may be a sensing-storage-computing integrated macro unit circuit of a distance measurement sensor, such as Figure 2 As shown, the PE unit includes a sensing unit SU, an analog signal operator operation unit AOP, an analog storage unit AREG bank, a digital storage unit DREGbank, a tag module TAG, an adjacent PE communication unit adjacent IF, an iSC bus, and an INS bus. The above units and modules are connected to the iSC bus and the INS bus. The iSC bus is used to transmit sensing signals and operation signals, and the sensing unit and the storage unit are both connected to the iSC bus; the INS bus is used to transmit instructions. The tag module is used to read the analog signal from the iSC bus; traverse and compare the read analog signal with a plurality of reference analog signals, and output the comparison result; the output module is used to output a digital signal according to the comparison result and the reference analog signal; the first control module is used to provide a reference analog signal to the tag module, and the plurality of reference analog signals are data that gradually increase or decrease with a functional relationship.

[0086] In one embodiment, the reference analog signal gradually increases or decreases with the number of times according to a linear function, an exponential function, a logarithmic function, a power function or a trigonometric function relationship.

[0087] In one embodiment, the encoding module is used to correspond the reference analog signal and the digital signal according to a certain encoding rule, and the encoding rule of the digital signal is standard binary code, Gray code, Hamming code or Huffman code.

[0088] In one embodiment, outputting a corresponding digital signal according to the comparison result and the reference analog signal further comprises the steps of:

[0089] The initialization value of the digital storage unit is 0;

[0090] When the comparison result of the tag module is that the analog signal is less than the reference analog signal, the digital signal stored in the digital storage unit changes a value according to the encoding rule each time the comparison is performed until the analog signal is greater than or equal to the reference analog signal, and the digital storage unit outputs the stored digital signal.

[0091] In one embodiment, the sensing unit, analog storage and computing unit, digital storage and computing unit, iSC bus, INS bus and tag module are integrated on the same chip.

[0092] In one embodiment, the analog storage and computing unit includes multiple analog signal memories, which also serve as analog computing units. By connecting the multiple analog storage and computing units to the same iSC bus for read and write operations, analog signals can be directly added, subtracted, multiplied, and divided in the analog signal memories.

[0093] In one embodiment, the digital storage and computing unit includes a plurality of digital signal memories, and the digital signal memories have both storage and logic operation capabilities.

[0094] In one embodiment, a DREG BANK is provided in the digital storage and computing unit, and the DREG BANK includes multiple digital signal memories, a digital read bus iSC RD data bus and a digital write bus iSC WR data bus, and the digital signal memory is a digital register DREG; multiple digital registers DREG are connected in parallel between the digital read bus iSC RD data bus and the digital write bus iSC WR data bus, wherein the input end IN of the digital register DREG is connected to the iSCWR data bus, and the output end OUT of the digital register DREG is connected to the iSC RD data bus, and a multiplexer MUX is also connected between the digital read bus iSCRD data bus and the digital write bus iSC WR data bus, and the digital read bus iSC RD data bus of the digital register DREG is also connected to the iSC bus through a switch.

[0095] In one embodiment, the digital signal memory is implemented using 3T DRAM, or 6T DRAM, or SRAM.

[0096] In one embodiment, the digital signal memory is implemented using Flash, which further includes: multiple FLASH memories, a read-write control circuit, a read data iSC RD data bus and a multiplexer MUX, wherein the input end IN of the FLASH memory is connected to the read-write control circuit, the output end of the FLASH is connected in parallel to the iSC RD data bus, and a multiplexer MUX is connected between the iSC RD data bus and the read-write control circuit.

[0097] In one embodiment, it also includes: identification data is stored in the label module, and whether the current sensing, storage and computing integrated macro unit circuit executes the instruction sent by the INS bus is determined based on the stored identification data.

[0098] In one embodiment, during operation, one or more digital register DREG signals read out from the digital read bus iSC RD data bus are written back to the digital write bus iSC WR data bus through the multiplexer MUX and then written into the corresponding one or more digital registers DREG to implement the operation.

[0099] In one embodiment, each label module corresponds to a processing unit, which is used to determine whether the current processing unit PE executes the current INS instruction based on the comparison result stored in the label module, that is, the identification data; when the comparison result stored in the label module is a first value, the corresponding processing unit executes the current INS instruction, and when the comparison result stored in the label module is a second value, the corresponding processing unit does not execute the current INS instruction.

[0100] In one embodiment, the analog storage and calculation unit includes a number of analog signal memories AREG0, AREG1..., and the analog signal memory itself is also an operation unit. The signal can be added, subtracted, multiplied and divided through the analog memory. For example, 5 registers can be designed to meet basic calculation requirements. Similarly, the digital storage and calculation unit is provided with a DREG BANK, and the DREG BANK includes a plurality of digital signal memories, and the digital signal memory is a digital register DREG; a dedicated digital read bus iSC RD bus and a digital write bus iSC WR bus are designed in the DREGBANK, and multiple DREG read control signals RD are opened to the read bus at the same time, so as to realize the line and operation of storing digital signals. The digital read bus can pass the signal to the iSC bus through the selection tube for further operation. A multiplexer MUX is designed between the two buses to write the read signal of the read bus back to the write bus and then write it to the corresponding DREG. The written back signal can be the same as the original signal and can also be selected to be inverted and written back. This is the role of the multiplexer MUX, refer to Figure 3, multiple digital registers DREG0, DREG1, ... are connected in parallel between the digital read bus iSC RD DBUS and the digital write bus iSC WR DBUS. In addition to storing digital signals, the digital signal memory can also perform logical operations. Among them, the input terminal IN of the digital register DREG is connected to the iSC WRDBUS, the output terminal OUT of the digital register DREG is connected to the digital read bus iSC RD DBUS, and a multiplexer MUX is also connected between the digital read bus iSCRD DBUS and the digital write bus iSC WR DBUS. The digital read bus iSCRD DBUS of the digital register DREG is also connected to the iSC bus through a switch.

[0101] The digital signal memory is implemented by 3T DRAM, or 6T DRAM, or SRAM. 6T SRAM is used as the circuit for digital signal storage DREG in PE. Compared with the previous DRAM, the storage is more stable, but the unit size of DREG will be increased. Data is written through the MWR tube, WR is valid, IN inputs a valid signal, and the write operation is completed. Correspondingly, data is read out through the MRD tube, RD is valid, OUT outputs a valid signal, and the read operation is completed. In this embodiment, the specific RAM reference Figure 4 .

[0102] In one embodiment, in addition to performing conventional operations through analog registers, the analog signal operator operation unit AOP can independently design efficient special operators to implement special operations, such as square operations, log operations, square root operations, etc., according to the particularity of the application scenario.

[0103] During operation, one or more digital register DREG signals read out by the digital read bus iSC RD DBUS are written back to the digital write bus iSC WR DBUS through the multiplexer MUX and then written into the corresponding one or more digital registers DREG to implement the operation.

[0104] In one embodiment, the tag module determines whether the current sensing-storage-computing-in-one macro unit circuit executes the instruction sent by the INS bus based on the stored identification data.

[0105] In one embodiment, reference Figure 5 The tag unit includes a comparator for reading an analog signal from the iSC bus; traversing and comparing the read analog signal with a number of reference analog signals, and outputting a digital signal according to the comparison result.

[0106] In one embodiment, the output of the tag module is used as a judgment signal or an enable signal to control whether the current PE executes the global SIMD instruction. For a PE designed with a TAG module, when the TAG output state is "invalid", the current PE does not execute the current instruction. On the contrary, when the TAG output state is "valid", the current PE executes the current instruction. The signal affecting the TAG tag module comes from the operation process of the analog register, such as signal overflow after operation, and the numerical judgment of the digital signal "0" and "1", as well as other operation results. The TAG tag module is designed to consist of a comparator circuit and a latch circuit. The comparator circuit is used to compare the signal on the iSC bus with the reference input signal, and then the output result of the comparator is stored in the latch behind. The TAG tag module controls the PE internal perception unit, analog storage unit, digital storage unit, and adjacent PE communication module, and controls the read and write operations or working states of the above unit circuits through the enable circuit. The control range of the TAG tag module is only the current PE. The chip restores the TAG to its initial state through the global TAG reset signal.

[0107] In this embodiment, in the digital-to-analog conversion mode, the comparator circuit of the label module is used to compare the analog signal with a number of reference analog signals, and the latch is used to store the comparison result. When the comparison result stored in the label module is a first value, the corresponding processing unit executes the current instruction, and when the comparison result stored in the label module is a second value, the corresponding processing unit does not execute the current instruction.

[0108] In the non-digital-to-analog conversion mode, the comparator also compares the identification data and the input reference signal, and then stores the output result of the comparator in the subsequent latch; when the comparison result stored in the label module is a first value, the corresponding processing unit executes the current instruction, and when the comparison result stored in the label module is a second value, the corresponding processing unit does not execute the current instruction.

[0109] The PE also designs the communication interface between adjacent PEs. Figure 2 The adjacent PE communication unit (Adjacent IF) can provide the current PE with information about the eight PEs surrounding the current PE. The above module units are connected together through a specially designed sense-storage-computing bus iSC bus. The analog signal can be a voltage or a current signal. In addition to the iSC bus, a global instruction bus INS bus is also designed in the PE to perform overall operation control on each functional module in the PE. Because the INS bus of each PE is controlled by the same global signal, storage-computing integration (SIMD) is achieved in this way.

[0110] In one embodiment, the original signal may come from the SU unit, or be written into the PE from outside the chip, such as the IO access in the figure, or the signal of the adjacent PE, which is transmitted to the PE bus through the adjacent IF. The SU, IO or adjacent IF transmits the sensing signal to the analog register AREG BANK or the AOP unit through the iSC bus. The AREG can be stored and calculated. The specific implementation method is described in detail below. The analog signal is converted into a digital signal and then stored in the DREGBANK, which can be digitally calculated and stored. The calculation result can be stored in the AREG or DREG of the PE, and then output to the outside of the chip through the iSC bus or other buses and transmission lines to realize a certain type of application function.

[0111] In one embodiment, it further includes: a DAC unit arranged outside the array structure, and the external DAC unit serves as a first control module.

[0112] In one embodiment, the sensing, storage and computing integrated macro unit circuit array is located on the same chip, and the external DAC is located inside or outside the chip.

[0113] In one embodiment, the sensing, storage and computing integrated macro unit circuit also includes: a second control module, which is used to initialize the digital storage and computing unit to 0; when the comparison result of the label module is that the analog signal is less than the reference analog signal, the digital signal stored in the digital storage and computing unit changes a value according to the encoding rule for each comparison until the analog signal is greater than or equal to the reference analog signal, and the digital storage and computing unit obtains a digital signal.

[0114] The following is further explained in conjunction with the sensing, storage and computing integrated macro unit circuit and its analog-to-digital conversion method.

[0115] refer to Figure 6 In this embodiment, the analog-to-digital conversion method of the sensing-storage-computing integrated macro unit circuit includes the following steps:

[0116] The tag module reads the analog signal from the iSC bus;

[0117] The tag module compares the read analog signal with several reference analog signals;

[0118] Obtaining a corresponding digital signal according to the comparison result;

[0119] The plurality of reference analog signals are data that gradually increase or decrease along a functional relationship.

[0120] Among them, several reference analog signals are data that gradually increase or decrease along with a functional relationship.

[0121] In one embodiment, the reference analog signal gradually increases or decreases with the number according to a linear function, an exponential function, a logarithmic function, a power function or a trigonometric function relationship.

[0122] In one embodiment, the encoding rule of the digital signal is standard binary code, Gray code, Hamming code or Huffman code.

[0123] The present invention realizes the conversion from PE analog domain to digital domain, that is, converting the analog signal in PE into the corresponding digital signal. The following example converts the analog signal of AREG in PE, such as the current signal, into 3-bit precision. In actual use, 5-bit precision or even higher 8-bit digital signal can be used and stored in the digital memory DREG.

[0124] In this embodiment, the original signal can come from the SU unit, or be written into the PE outside the chip, or it can come from the analog register AREG BANK, or the AOP unit, and then sent to the iSC bus. The TAG unit receives the analog signal from the iSC bus, and thus can obtain the converted digital signal according to the size of the AREG analog current signal and the size of the voltage input at the negative input terminal, and then store it in the DREG BANK, and digital operations and storage can be performed. The operation result can be stored in the DREG of the PE, and then output to the outside of the chip through the iSC bus to realize a certain type of application function. In the analog-to-digital conversion step, the analog storage unit sends the analog signal to the iSC bus.

[0125] All the above data transmission and signal collection require INS command control. The INS bus connects the components in each PE. The INS can come from the system outside the chip, or it can be issued by the MCU module inside the chip, or the chip itself generates an INS for specific applications. The label module determines whether the current sensing, storage and computing macro unit circuit executes the instruction sent by the INS bus based on the stored identification data.

[0126] Specifically, in this embodiment, the storage current range of AREG is -8uA to 8uA, and the voltage output to the iSC bus will also change accordingly, from 0.2V to 0.9V.

[0127] Specifically, the output of the tag module is used as a judgment signal or an enable signal to control whether the current PE executes the global SIMD instruction. For a PE with a TAG module, when the TAG output status is "invalid", the current PE does not execute the current instruction. On the contrary, when the TAG output status is "valid", the current PE executes the current instruction. The signal that affects the TAG tag module comes from the operation process of the analog register, such as signal overflow after operation, digital signal "0" and "1" value judgment, and other operation results. The TAG tag module is designed by a comparator circuit such as Figure 5 As shown in the figure, the comparator circuit is used to compare the signal on the iSC bus with the reference input signal, and then the output result of the comparator is stored in the latch behind. TAG controls the internal sensing unit, analog storage unit, digital storage unit, and adjacent PE communication module of the PE, and controls the read and write operation or working status of the above unit circuits through the enabling circuit. The control range of the TAG tag module is only the current PE. The chip restores the TAG to its initial state through the global TAG reset signal.

[0128] In one embodiment, the step is further included: the tag module determines whether the current sensing-storage-computing-in-one macro unit circuit executes the instruction sent by the INS bus based on the stored identification data.

[0129] In one embodiment, the steps are further included: in the digital-to-analog conversion mode, the comparator circuit is used to compare the analog signal with a plurality of reference analog signals, the latch is used to store the comparison result, when the comparison result stored in the label module is a first value, the corresponding processing unit executes the current instruction, and when the comparison result stored in the label module is a second value, the corresponding processing unit does not execute the current instruction.

[0130] In one embodiment, the steps are further included: in a non-digital-to-analog conversion mode, the comparator also compares the identification data and the input reference signal, and then stores the output result of the comparator in a subsequent latch; when the comparison result stored in the label module is a first value, the corresponding processing unit executes the current instruction, and when the comparison result stored in the label module is a second value, the corresponding processing unit does not execute the current instruction.

[0131] The specific D / A conversion mode and non-D / A conversion mode can be selected by connecting a multi-way selection switch at the reference signal input terminal of the comparator, for example, selecting to input the reference analog signal in the D / A conversion mode, and selecting to input the comparison reference signal with the identification data in the non-D / A conversion mode. In addition, a multi-way selection switch can be set at the positive input terminal of the comparator to select to read the analog signal from the iSC bus in the corresponding mode.

[0132] Because the main circuit of the TAG module is the comparator circuit, the characteristics of the TAG comparator are used to realize the ADC function in the PE, that is, to realize the mutual conversion of analog domain signals in the PE to digital domain signals. Specifically, the iSC bus is connected to the positive end of the comparator in the TAG. The negative end of the comparator in the TAG inputs the reference analog signal.

[0133] Specifically, the AREG or SU can send an analog signal to the iSC bus. The TAG includes a comparator circuit inside to compare the magnitude of the analog signal obtained from the iSC and the reference analog signal. Figure 5As shown, the gate input voltage signal A of the MOS tube M171, the gate input voltage signal B of the MOS tube M172, and the drain of the MOS tube M172 are used as the output terminal. The comparator circuit is used to compare the sizes of the two signals. When A is smaller than B, the output of TAG will become 0, or the output terminal of the analog register AREG is input to the B terminal, and the reference analog signal voltage is input to the A terminal to determine whether the value of AREG exceeds the given reference analog signal voltage. If it exceeds, it becomes 0, and if it is lower than the threshold, it becomes 1.

[0134] For example, in this embodiment, the DAC unit outside the PE array is connected to the negative end of the comparator in the TAG to provide a reference analog signal. Figure 8 and Fig. 9 The DAC module on the chip can be used to generate a ramp step voltage and output it to the negative end of the comparator. The output range is equivalent to the signal range stored in AREG. The change of the ramp step output voltage is related to the quantization accuracy. For example, 3-bit quantization accuracy requires 8 step voltage values. This correspondence is a linear relationship. The size of the code is linearly related to the quantized voltage.

[0135] In this embodiment, the coding rule of the digital signal is a standard binary code, and in other embodiments, it can also be based on Gray code, Hamming code or Huffman code, etc., all of which are within the scope of protection of the present invention. The reference analog signal gradually increases or decreases with the number of times according to a linear function, exponential function, logarithmic function, power function or trigonometric function relationship. In another embodiment of this invention, another nonlinear quantization method is used to adjust the output characteristics of the DAC to make it nonlinear output, such as a LOG curve, and corresponding to a linear digital code, which can achieve a quantization conversion method with a higher dynamic range, especially data conversion for optical imaging.

[0136] In one embodiment, if Figure 7 As shown in the figure, the control process is controlled by instructions. The chip performs operations according to the instructions, and the entire PE array operates in SIMD mode. The specific operation process and steps of converting analog signals into digital signals are as follows:

[0137] S10: The TAG unit is reset and the TAG value becomes "0".

[0138] S20: DREGs is initialized to 0, and DREG1, DREG2, and DREG3 are stored as initial values, such as 000.

[0139] S30: The TAG unit compares the analog signal with the reference analog signal.

[0140] The TAG unit receives an analog signal from the iSC bus, and the external DAC provides an analog reference signal, such as 0.2V, to the TAG unit.

[0141] S40: assign a TAG value according to the comparison result; if the TAG unit comparison analog signal is smaller than the reference analog signal, TAG=0, and execute step S50.

[0142] Otherwise, TAG=1, and execute step S60.

[0143] S50: DREGs changes a value according to the coding rules, for example, adds 1, and the corresponding values ​​of the three bits DREG1, DREG2, and DREG3 change, and the external DAC provides an analog reference signal to the TAG unit that increases by a fixed value, for example, 0.1v, and the reference analog signal increases to 0.3v, and returns to execute step S30.

[0144] S60: DREGs are locked and a digital-to-analog conversion is completed.

[0145] Therefore, in steps S30 and S40, the loop is continued until one digital-to-analog conversion is completed.

[0146] The specific corresponding relationships are as follows:

[0147] If the analog signal is less than 0.2V, DREGs is set to 000;

[0148] When the analog signal is between 0.2V and 0.3V, DREG is set to 001;

[0149] When the analog signal is between 0.3V-0.3V, DREG is set to 010;

[0150] When the analog signal is between 0.4V and 0.5V, DREG is set to 011;

[0151] When the analog signal is between 0.5V and 0.6V, DREG is set to 100;

[0152] When the analog signal is between 0.6V and 0.7V, DREG is set to 101;

[0153] When the analog signal is between 0.7V and 0.8V, DREG is set to 110;

[0154] When the analog signal is between 0.8V and 0.9V, DREG is set to 111;

[0155] The counter function is realized by controlling multiple DREGs through global instructions. For example, 3-bit precision conversion requires 3 DREGs, DREG0 / DREG1 / DREG2. Let DREG0 / DREG1 / DREG2 change from "000" to "111". At the same time, each time the value changes, the negative input of the comparator corresponds to the voltage. When the voltage of the negative input of the comparator is equivalent to or greater than the iSC bus voltage, the comparator output in TAG changes from 0 to 1, and the TAG value becomes 1. At this time, the current PE will not respond to the global instruction, and the value in DREG0 / DREG1 / DREG2 will not be output. The current value is locked and no longer changes with INS control. The value at this time corresponds to the size of the analog signal. DREG locks the current value and no longer responds to the global DREG operation, that is, a digital-to-analog conversion is completed.

[0156] In another embodiment, as shown in the figure, the reference analog signal may be gradually increased with the number of times according to a logarithmic function relationship.

[0157] In another embodiment, reference Fig.10 , the encoding rule of digital signals is to use Gray code. Gray code can improve quantization efficiency, because the change between natural number sequences involves multiple bits changing at the same time, which requires multiple instructions to achieve the corresponding value change. If Gray code is used, only one bit needs to change between each number, that is, only one instruction is needed to achieve the change of the corresponding value sequence. Figure 3 The bit sequence and 4-bit value sequence change.

[0158] The specific corresponding relationships are as follows:

[0159] If the analog signal is less than 0.2V, DREG is set to 000;

[0160] When the analog signal is between 0.2V and 0.3V, DREG is set to 001;

[0161] When the analog signal is between 0.3V-0.3V, DREG is set to 011;

[0162] When the analog signal is between 0.4V and 0.5V, DREG is set to 010;

[0163] When the analog signal is between 0.5V and 0.6V, DREG is set to 110;

[0164] When the analog signal is between 0.6V and 0.7V, DREG is set to 111;

[0165] When the analog signal is between 0.7V and 0.8V, DREG is set to 101;

[0166] When the analog signal is between 0.8V and 0.9V, DREG is set to 100.

[0167] In another embodiment, 4-bit encoding may be used, that is, the accuracy of DREG is 4 bits.

[0168] The specific corresponding relationships are as follows:

[0169] If the analog signal is less than 0.2V, DREG is set to 0000;

[0170] When the analog signal is between 0.2V and 0.25V, DREG is set to 0001;

[0171] When the analog signal is between 0.25V and 0.3V, DREG is set to 0011;

[0172] When the analog signal is between 0.3V and 0.35V, DREG is set to 0010;

[0173] When the analog signal is between 0.35V and 0.4V, DREG is set to 0110;

[0174] When the analog signal is between 0.4V and 0.45V, DREG is set to 0111;

[0175] When the analog signal is between 0.45V and 0.5V, DREG is set to 0101;

[0176] When the analog signal is between 0.5V and 0.55V, DREG is set to 0100;

[0177] When the analog signal is between 0.55V and 0.6V, DREG is set to 1100;

[0178] When the analog signal is between 0.6V and 0.65V, DREG is set to 1101;

[0179] When the analog signal is between 0.65V and 0.7V, DREG is set to 1111;

[0180] When the analog signal is between 0.7V and 0.75V, DREG is set to 1010;

[0181] When the analog signal is between 0.75V and 0.8V, DREG is set to 1011;

[0182] When the analog signal is between 0.8V and 0.85V, DREG is set to 1001;

[0183] The analog signal is between 0.85V-0.9V, and DREG is set to 1000.

[0184] To convert conventional analog signals to digital signals, a special ADC chip or ADC circuit is needed to realize the conversion. For traditional image sensors, the early single ADC has developed to column-level ADC, and then to the latest pixel-level ADC design, but this requires advanced process requirements. Because of the ADC design size limitation and ADC frequency characteristic requirements, the traditional data handling process results in high processing delay and high power consumption.

[0185] Especially for the sensing storage chip, there are analog signal operation and storage units and digital signal operation and storage units in the PE. When the signal interacts or flows in the analog domain and the digital domain, it faces great problems. Either the ADC circuit is designed in the PE, but it brings problems of circuit area and power consumption. Or a single ADC circuit is used for serial conversion, which brings efficiency problems, data flow delay, and power consumption problems.

[0186] The present invention utilizes the quantized digital signal and stores it in DREGs, which can be used for digital domain calculations or as the final calculation result. The present invention provides a method for parallelizing analog domain to digital domain signal conversion in PE. This method does not require a dedicated ADC circuit, but uses the existing circuit of PE to realize the conversion function. This parallel conversion is equivalent to pixel-level or PE-level signal conversion, with high efficiency and high bandwidth, and is very suitable for visual signal processing and conversion. Output to the digital system of the chip post-stage, such as MCU.

[0187] By utilizing existing components in PE, such as comparators, analog signals such as Pixel signals and AREG current signals are converted into digital signals and stored in DREG in PE. This method realizes parallel analog domain to digital domain signal conversion without adding special conversion circuits. This method does not require a dedicated ADC circuit and utilizes the existing circuits of PE to realize the conversion function. This parallel conversion is equivalent to pixel-level signal conversion, with high efficiency and high bandwidth, and is very suitable for visual signal processing and conversion.

[0188] In line with the SIMD execution mode of the memory computing chip, this conversion method only circulates in the PE and does not need to be transmitted outside the PE. This reduces the flow of data and greatly reduces the delay and power consumption caused by data transportation.
