Description

Technical Field

[0001] The present application relates to but is not limited to the field of millimeter wave chip technology, and in particular to a cascade processing method, data transmission interface, device, and medium for a millimeter wave chip. Background Art

[0002] The existing millimeter wave chips are mainly divided into two categories: RF chips and SOC chips. Among them, RF chips generally only output intermediate frequency signals after detection, and specific sampling and subsequent data processing are completed by the main control; among them, SOC chips integrate functions such as RF, sampling, and data processing. The data transmission interfaces are basically integrated with existing conventional IP cores, such as SPI, UART, Ethernet, etc. The cost of integrating these interfaces is high. Based on this, the application of cascade chips has been proposed. For example, multiple SOC chips of the same type are cascaded and work together to improve data processing performance while avoiding the use of higher-configuration chips to reduce costs. However, when the chip is cascaded, the data transmission method is relatively limited. Data can only be transmitted according to the fixed architecture and protocol of the chip. For example, the transmission between the front-stage chip and the back-stage chip must be maintained at the same clock and cannot be changed according to actual application requirements.

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It is understood that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flow chart. The terms "first", "second", etc. in the specification, claims or the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] The existing millimeter wave chips are mainly divided into two categories: RF chips and SOC chips. Among them, RF chips generally only output intermediate frequency signals after detection, and specific sampling and subsequent data processing are completed by the main control; among them, SOC chips integrate functions such as RF, sampling, and data processing. The data transmission interfaces are basically integrated with existing conventional IP cores, such as SPI, UART, Ethernet, etc. The cost of integrating these interfaces is high. Based on this, the application of cascade chips has been proposed. For example, multiple SOC chips of the same type are cascaded and work together to improve data processing performance while avoiding the use of higher-configuration chips to reduce costs. However, when the chip is cascaded, the data transmission method is relatively limited. Data can only be transmitted according to the fixed architecture and protocol of the chip. For example, the transmission between the front-stage chip and the back-stage chip must be maintained at the same clock and cannot be changed according to actual application requirements.

[0042] In order to solve the above-mentioned problems, the embodiment of the present application provides a cascade processing method, data transmission interface, device, and medium of a millimeter wave chip, the method comprising: obtaining the target data from the previous chip or the next chip, and storing the target data in the data storage unit; determining the chip type of the next chip, and determining the target data transmission mode based on the chip type, the target data transmission mode being a full-duplex transmission mode or a half-duplex transmission mode; based on the target data transmission mode, adjusting the target enable mode of the data signal line, the valid flag signal line, the clock signal line, and the reset signal line respectively through the register management unit, and enabling each signal line in the physical IO interface based on the corresponding target enable mode to transmit the target data to the next chip or the previous chip. According to the scheme provided by the embodiment of the present application, the actual data transmission requirements of different types of next chips are different, and the target enable mode of each signal line of the data transmission interface is adaptively adjusted based on the type of the next chip, thereby realizing the improvement of the application flexibility of the millimeter wave cascade chip.

[0043] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0044] refer to Figure 1 , Figure 1is a flowchart of a cascade processing method of a millimeter wave chip provided by an embodiment of the present application. The embodiment of the present application provides a cascade processing method of a millimeter wave chip, which is applied to Figures 2 to 4 The data transmission interface 300 shown in FIG. 1 is electrically connected to the front-stage chip 100 and the rear-stage chip, respectively. The rear-stage chip may be as shown in FIG. Figure 3 The FPGA chip 210 shown, or Figure 4 The chip type shown is a millimeter wave chip rear chip 220, the front chip 100 is a millimeter wave chip, the data transmission interface 300 includes a physical IO interface, a data storage unit 302 and a register management unit 301, the physical IO interface includes a data signal line 304, a valid flag signal line 303, a clock signal line and a reset signal line 307, and the method includes but is not limited to the following steps:

[0045] Step S10, acquiring target data from a previous chip or a subsequent chip, and storing the target data in a data storage unit.

[0046] Specifically, refer to Figure 2 The data transmission interface 300 of this embodiment includes a data storage unit 302, which is used to store target data from the previous chip 100 or the next chip 210 / 220 before determining the data transmission mode between the previous and next chips.

[0047] Specifically, Figure 2 As shown, the data transmission interface 300 of this embodiment also includes a working clock, which is provided by the previous-stage chip 100 to the data transmission interface 300 module for operation. The data storage unit 302, the register management unit 301 and the working clock unit are all electrically connected to the chip core of the previous-stage chip 100, and the physical IO interface of the data transmission interface 300 is electrically connected to the chip Pad of the subsequent-stage chip.

[0048] Step S20, determining the chip type of the subsequent chip, and determining a target data transmission mode based on the chip type, the target data transmission mode being a full-duplex transmission mode or a half-duplex transmission mode.

[0049] Specifically, this embodiment does not limit the specific chip type of the subsequent chip, which may be the same as the previous chip 100, a millimeter wave chip, or an FPGA chip, etc., and technicians in this field may select it according to actual needs.

[0050] Specifically, in one embodiment, Figure 1 Step S20 includes but is not limited to the following steps:

[0051] Step S21, when the chip type characterizes that the subsequent chip is an FPGA chip, the half-duplex transmission mode is determined as the target data transmission mode;

[0052] Step S22: When the chip type characterizes that the subsequent chip is a millimeter wave chip, the full-duplex transmission mode is determined as the target data transmission mode.

[0053] Specifically, the specific method for determining the target data transmission mode of the data transmission interface of the present embodiment is based on considerations such as the hardware compatibility between the front-stage chip 100 and the back-stage chip, signal processing and power consumption, and application requirements. For example, when the back-stage chip is an FPGA chip, considering that the FPGA chip requires additional signal processing circuits and power consumption when processing millimeter-wave signals, and the half-duplex transmission mode can reduce the complexity and power consumption of signal processing, the half-duplex transmission mode is more suitable for data transmission between the FPGA chip and the millimeter-wave chip; and considering that there is a high bandwidth requirement between millimeter-wave chips, and the millimeter-wave chip has a built-in module that supports the full-duplex transmission mode, therefore, when the front-stage and back-stage chips in the cascade chip are both millimeter-wave chips, the use of the full-duplex transmission mode can maximize the use of bandwidth resources and improve data transmission efficiency and reliability.

[0054] Step S30, based on the target data transmission mode, adjust the target enable modes of the data signal line, the valid flag signal line, the clock signal line and the reset signal line respectively through the register management unit, and enable each signal line in the physical IO interface based on the corresponding target enable mode to transmit the target data to the subsequent chip or the previous chip.

[0055] It can be understood that the data transmission interface applied to cascade chips in this embodiment can adjust the target data transmission mode based on the hardware characteristics of the previous and next chips and the transmission requirements of the target data, determine the target enable mode of each signal line in the physical IO interface corresponding to the target data transmission mode, and configure and enable each signal line in the physical IO interface through the register management unit based on the target enable mode to realize data transmission between the previous and next chips. Compared with the existing data transmission interface that can only perform data transmission in a fixed transmission mode, this embodiment can improve the application flexibility and versatility of the data transmission interface, while enabling the millimeter wave chip to have large data throughput and high frame rate, thereby improving the transmission performance between millimeter wave cascade chips.

[0056] In addition, in some embodiments, reference Figure 2 and Figure 3 In the case where the chip type characterizes that the subsequent chip is an FPGA chip, the half-duplex transmission mode includes a half-duplex receiving mode and a half-duplex sending mode, and the clock signal line includes a clock input signal line 306 and a clock output signal line 305. In this case, Figure 1In step S30, based on the target data transmission mode, the target enable modes of the data signal line, the valid flag signal line, the clock signal line, and the reset signal line are respectively adjusted by the register management unit, and each signal line in the physical IO interface is enabled based on the corresponding target enable mode, including but not limited to the following steps:

[0057] Step S31, when the target enable mode is the half-duplex transmission mode, enable the clock output signal line, enable the data signal line, and determine the input and output direction of the data signal line as output, and enable the valid flag signal line and the reset signal line;

[0058] or,

[0059] Step S32, when the target enable mode is the half-duplex receiving mode, enable the clock input signal line, enable the data signal line, and determine the input and output direction of the data signal line as input, and enable the valid flag signal line and the reset signal line.

[0060] Specifically, in this embodiment, the valid flag signal line is enabled by default and used as an output. In the valid flag signal transmitted by the valid flag signal line, the data transmission of the target data starts from the timestamp corresponding to the rising edge, and the data transmission ends at the timestamp corresponding to the falling edge. The register management unit can also be configured to start the data transmission of the target data from the timestamp corresponding to the falling edge, and end the data transmission at the timestamp corresponding to the rising edge. No restrictions will be made here.

[0061] It is understandable that when the chip type characterizes that the subsequent chip is an FPGA chip, reference Figure 3 In this embodiment, the target enable mode of the data transmission interface is a half-duplex transmission mode, and the half-duplex transmission mode corresponds to a half-duplex sending mode and a half-duplex receiving mode. Specifically, when the target enable mode is the half-duplex sending mode, the clock output signal line is enabled, the data signal line is enabled, and the input and output direction of the data signal line is determined to be output, and the valid flag signal line and the reset signal line are enabled; and when the target enable mode is the half-duplex receiving mode, the clock input signal line is enabled, the data signal line is enabled, and the input and output direction of the data signal line is determined to be input, and the valid flag signal line and the reset signal line are enabled. That is to say, the data transmission interface 300 of this embodiment can dynamically configure the target enable modes of different signal lines in the physical IO interface adaptively according to different half-duplex requirements, thereby improving the application flexibility of the interface.

[0062] In addition, in some embodiments, when the chip type characterizes that the subsequent chip is an FPGA chip, the cascade processing method of the millimeter wave chip in the embodiment of the present application also includes but is not limited to the following steps:

[0063] Step S311, when the target data comes from the previous chip, determine the first number of data signal lines that meet the current data transmission requirement according to the data volume of the target data, and when the first number is less than the total number of data signal lines, calculate a first difference between the total number and the first number, and turn off the enable signal of the data signal lines whose number is the first difference;

[0064] or,

[0065] Step S321, when the target data comes from the subsequent chip, determine the second number of data signal lines that meet the current data receiving requirements based on the data volume of the target data; when the second number is less than the total number of data signal lines, calculate the second difference between the total number and the second number, and turn off the enable signal of the data signal lines whose number is the second difference.

[0066] It can be understood that the present embodiment also adjusts the number of enabled data signal lines according to the amount of target data currently received or to be sent. Specifically: Figure 3 When the target data comes from the front-stage chip 100, the first number of data signal lines 304 that meet the current data sending requirements is determined according to the data volume of the target data. When the first number is less than the total number of data signal lines 304, the first difference between the total number and the first number is calculated, and the enable signal of the data signal lines 304 whose number is the first difference is turned off; when the target data comes from the back-stage chip 210 (i.e., the FPGA chip), the second number of data signal lines 304 that meet the current data receiving requirements is determined according to the data volume of the target data. When the second number is less than the total number of data signal lines 304, the second difference between the total number and the second number is calculated, and the enable signal of the data signal lines 304 whose number is the second difference is turned off. While enhancing flexibility, it can effectively save hardware resources, reduce the overall power consumption of the system, improve transmission efficiency, and reduce the maintenance cost of signal transmission lines.

[0067] Specifically, this embodiment does not involve improvements to the millimeter wave chip. For example, Figure 3 and Figure 4 The front-stage chip 100 of this embodiment includes a radio frequency unit 110, an ADC sampling unit (i.e., a digital-to-analog interface 120), and an algorithm unit 130 including a 1-dimensional FFT operation unit, a 2-dimensional FFT operation unit, a 3-dimensional FFT operation unit, and a CFAR operation unit. Starting from the digital-to-analog interface 120, the output data can be sent out through the data transmission interface 300 of the embodiment of the present application. At the same time, the data received by the data transmission interface 300 from the rear-stage chip can be sent to the front-stage chip 100 and processed again by the core processor 140 of the front-stage chip 100.

[0068] Specifically, in a specific embodiment, referring to Figure 3In the case where the front-stage chip 100 is a millimeter wave chip and the back-stage chip is an FPGA chip 210, half-duplex is mainly used to transmit large data packets in this application. After the front-stage chip 100 completes ADC sampling or 1D FFT operation or 2D FFT operation or 3D FFT operation or CFAR operation through the digital-analog interface 120 and the algorithm unit 130 to obtain the target data, the target data is sent to the FPGA chip through the data transmission interface 300. After the FPGA chip receives the data and performs further processing, it can choose to directly feedback the results or transmit it back to the front-stage chip 100 through the data transmission interface 300, and the front-stage chip 100 performs re-processing or result feedback. The advantage of this method is that when the hardware algorithm unit 130 integrated in the front-stage chip 100 cannot meet the application requirements, the algorithm can be secondary developed through the external FPGA chip 210 to meet the requirements of the application scenario.

[0069] In addition, in some embodiments, when the chip type characterizes that the subsequent chip is a millimeter wave chip, reference Figure 4 The data transmission interface 300 includes a first transmission interface 310 and a second transmission interface 320. The first transmission interface 310 includes a first IO interface, and the second transmission interface 320 includes a second IO interface. The first transmission interface 310 is electrically connected to the front-stage chip 100, and the second transmission interface 320 is electrically connected to the back-stage chip 210. The first IO interface includes a first data signal line 311, a first clock output signal line 313, a first clock input signal line 314, a first valid flag signal line 315 and a first reset signal line 316. The second IO interface includes a second data signal line 321, a second clock output signal line 323, a first valid flag signal line 315 and a first reset signal line 316. The first clock input signal line 324, the second valid flag signal line 325 and the second reset signal line 326, the first clock output signal line 313 is electrically connected to the second clock input signal line 324, the first clock input signal line 314 is electrically connected to the second clock output signal line 323, the first data signal line 311 is electrically connected to the second data signal line 321, the number of the first data signal line 311 and the second data signal line 321 is the same and the number is multiple, the first valid flag signal line 315 is electrically connected to the second valid flag signal line 325, and the first reset signal line 316 is electrically connected to the second reset signal line 326. In this case, Figure 1 In step S30, based on the target data transmission mode, the target enable modes of the data signal line, the valid flag signal line, the clock signal line, and the reset signal line are respectively adjusted by the register management unit, and each signal line in the physical IO interface is enabled based on the corresponding target enable mode, including but not limited to the following steps:

[0070] Step S33, enabling the first clock output signal line, the second clock output signal line, the first clock input signal line, and the second clock input signal line;

[0071] Step S34, enabling all the first data signal lines, determining the input / output direction of the third number of first data signal lines as output, and determining the input / output direction of the remaining fourth number of first data signal lines as input;

[0072] Step S35, enabling all the second data signal lines, determining the input / output direction of the third number of second data signal lines as input, and determining the input / output direction of the remaining fourth number of second data signal lines as output;

[0073] Step S36, enabling the first reset signal line, the second reset signal line, the first valid flag signal line and the second valid flag signal line.

[0074] Understandably, reference Figure 4 As described in the above embodiments, in the case where the front-stage chip 100 and the back-stage chip are both millimeter wave chips, two transmission interfaces need to be set, namely the first transmission interface 310 and the second transmission interface 320, the first transmission interface 310 and the second transmission interface 320 are connected one-to-one through the corresponding physical IO interface, the first clock output signal line 313 is electrically connected to the second clock input signal line 324, the first clock input signal line 314 is electrically connected to the second clock output signal line 323, the first data signal line 311 is electrically connected to the second data signal line 321, the number of the first data signal line 311 and the second data signal line 321 is the same and the number is multiple, the first valid flag signal line 315 is electrically connected to the second valid flag signal line 325, the first reset signal line 316 is electrically connected to the second reset signal line 326, and on this hardware basis, by enabling the first clock output signal Line 313, the second clock output signal line 323, the first clock input signal line 314 and the second clock input signal line 324; enable all the first data signal lines, determine the input and output direction of the third number of first data signal lines 311 as output, and determine the input and output direction of the remaining fourth number of first data signal lines 312 as input; enable all the second data signal lines, determine the input and output direction of the third number of second data signal lines 321 as input, and determine the input and output direction of the remaining fourth number of second data signal lines 322 as output; enable the first reset signal line 316, the second reset signal line 326, the first valid flag signal line 315 and the second valid flag signal line 325 to realize full-duplex data transmission between the front-stage chip 100 and the back-stage chip 210, so as to improve the transmission rate between the front-stage chip 100 and the back-stage chip 210.

[0075] In addition, in some embodiments, when the chip type characterization post-stage chip is a millimeter wave chip, the first transmission interface includes a first register management unit and a first data storage unit storing first target data, and the second transmission interface includes a second register management unit and a second data storage unit storing second target data. The cascade processing method of the millimeter wave chip in the embodiment of the present application also includes but is not limited to the following steps:

[0076] Step S37, obtaining a first data volume of the first target data and a second data volume of the second target data;

[0077] Step S38, based on the first data amount and the second data amount, the first register management unit in combination with the second register management unit updates the third quantity and the fourth quantity of the first data signal line, and updates the third quantity and the fourth quantity of the second data signal line.

[0078] Specifically, since the chip type characterizes that the rear-stage chip 210 is a millimeter wave chip, data transmission between the front-stage and rear-stage chips is realized through the first transmission interface 310 and the second transmission interface 320. This embodiment adjusts the number of data signal lines used as input and output by determining the first data amount and the second data amount. For example, this embodiment includes N data signal lines, and the third number of data signal lines (for example, the 1st to N / 2nd) are configured as outputs through the register unit, and the remaining fourth number of data signal lines, that is, the (N / 2+1)th to Nth data signal lines are configured as inputs; or the number of data bits is changed, and the 1st to N / 4th data signal lines are configured as outputs, and the remaining (N / 4+1)th to Nth data signal lines are configured as inputs. Technical personnel in this field adjust the specific number of data signal lines 304 and the specific configuration of the input and output directions of the data signal lines according to actual conditions.

[0079] It is understood that, in one embodiment, if Figure 4As shown, in the millimeter wave cascade chip, when the front-stage chip 100 and the rear-stage chip are both millimeter wave chips, full-duplex mode is mainly used to transmit data. At this time, the first data signal line 311 of the first transmission interface 310 connected to the front-stage chip 100 is configured so that the number of output signal lines is much greater than the number of input signal lines. For example, the front-stage chip 100 has 24 output signal lines and 8 input signal lines; accordingly, the second data signal line of the second transmission interface 320 connected to the rear-stage chip 210 is configured as 8 output signal lines and 24 input signal lines; the front-stage and rear-stage chips are connected, and the first valid flag signal line 315 connected to the first transmission interface 310 of the front-stage chip 100 is configured as output, and the second valid flag signal line 325 connected to the second transmission interface 320 of the rear-stage chip 210 is configured as output; the first clock output signal line 313 of the front-stage chip 100 is connected to the rear-stage chip 210. The first clock input signal line 324 of the chip 210 is electrically connected, and the first clock input signal line 314 of the front-stage chip 100 is electrically connected to the second clock output signal line 323 of the back-stage chip 210; after the front-stage chip 100 completes ADC sampling at the digital-to-analog interface 120, or completes 1-dimensional FFT operation, 2-dimensional FFT operation, 3-dimensional FFT operation or CFAR operation in the algorithm unit 130, the first target data obtained is sent to the back-stage chip through the data output signal line, and the back-stage chip 210 completes subsequent processing. The subsequent processing refers to the secondary processing result of the result of the FFT operation or the result of the CFAR operation performed by the algorithm unit 221 of the back-stage chip 210 in combination with the core processor 222. The amount of the result information data is much smaller than the amount of data sent by the front-stage chip, so at the same valid flag bit effective time, only a small number of data bits are needed to complete the data transmission. Furthermore, since the transmission clocks of the front-end and rear-end chips are independent, the data transmission time of the front-end chip 100 is used as the basis, and the data transmission rate of the rear-end chip can be individually configured according to actual application requirements (adjusting the number of inputs and outputs) to ensure that the information transmitted by the rear-end chip can be completed when the same valid flag takes effect.

[0080] In this way, this embodiment adjusts the enable mode of each signal line in the physical IO module of the data transmission interface based on actual data transmission requirements, such as adjusting the number of data bits used to transmit target data, thereby enhancing flexibility and effectively improving transmission efficiency.

[0081] In addition, in some embodiments, the cascade processing method of the millimeter wave chip provided in the embodiment of the present application includes but is not limited to the following steps:

[0082] Step S41, determining the transmission rate requirement of target data;

[0083] Step S42: Based on the transmission rate requirement, the clock output frequency of the clock signal line is adjusted by the register management unit.

[0084] It can be understood that this embodiment adjusts the clock output frequency of the clock signal line through the register management unit based on the transmission rate requirement of the target data, and can adjust the configuration of the data transmission interface based on the actual data transmission requirement, thereby enhancing the flexibility of interface application.
