Description

Technical Field

[0001] This application relates to the technical field of image data processing, and in particular to an image data transmission method, apparatus, computer device, storage medium, and computer program product. Background Art

[0002] In modern computer systems, the efficiency of data transmission directly affects the overall performance of the system. In the fields of semiconductors and image processing, high-speed image transmission technology is the key to realizing real-time image acquisition, processing, and display. Especially in fields involving high-speed data processing, such as real-time video processing and big data analysis, how to efficiently transmit data between the host and FPGA has become a key issue. In the field of semiconductor electron microscopy, image transmission technology is a crucial link to ensure the real-time and accurate transmission of high-resolution images. With the continuous progress of semiconductor manufacturing processes, the device size has gradually shrunk to the nanometer level, posing higher requirements for the resolution and accuracy of microscopic imaging. Electron microscopes (such as transmission electron microscopes TEM and scanning electron microscopes SEM) generate high-resolution images by the interaction of electron beams with samples. However, the amount of these image data is huge, and traditional wired transmission methods have limitations in terms of bandwidth and latency, making it difficult to meet the requirements of real-time processing and remote control.

[0003] In related technologies, with the development of high-speed network technology and image compression algorithms, image transmission technology has been significantly improved. For example, high-speed transmission systems based on optical fibers can achieve large-bandwidth and low-latency data transmission, while advanced image compression technologies (such as JPEG2000, HEVC) effectively reduce the amount of data while maintaining image quality. In addition, the introduction of wireless transmission technologies (such as 5G) further expands the application scenarios of remote microscopic imaging, enabling researchers to obtain and analyze microscopic images at a distance in real time. The combination of these technologies not only improves the efficiency and reliability of image transmission but also provides strong support for real-time monitoring and defect analysis in the semiconductor manufacturing process.

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.

[0068] In the related art, with the development of high-speed network technology and image compression algorithms, image transmission technology has been significantly improved. For example, high-speed transmission systems based on optical fibers can achieve large-bandwidth and low-latency data transmission, while advanced image compression technologies (such as JPEG2000 and HEVC) effectively reduce the amount of data while maintaining image quality. In addition, the introduction of wireless transmission technologies (such as 5G) further expands the application scenarios of remote microscopy, enabling researchers to obtain and analyze microscopic images at a distance in real time. The combination of these technologies not only improves the efficiency and reliability of image transmission but also provides strong support for real-time monitoring and defect analysis in the semiconductor manufacturing process.

[0069] However, the current image data transmission methods have the following technical problems:

[0070] The current image data transmission methods have the problem of process redundancy, resulting in poor real-time performance of data transmission.

[0071] Based on this, the embodiments of the present application provide an image data transmission method, device, computer device, storage medium, and computer program product.

[0072] The image data transmission method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Figure 1 An image data transmission system is shown, including an acquisition (SICU), a processing side, a storage (DMA), and a driving side.

[0073] In one embodiment, as Figure 2 shown, an image data transmission method is provided. Taking the application of this method to the Figure 1 image data transmission system as an example, the method includes the following steps:

[0074] Step 202: In response to the processing side obtaining the image data to be processed, store the image data in a predefined memory area.

[0075] Step 204: In response to the completion of storing the image data, the processing side generates an interrupt signal and sends it to the driving side.

[0076] Step 206: In response to the driving side obtaining the interrupt signal, read the image data from the memory area.

[0077] Step 208: The driving side transmits the obtained image data to the host computer to implement the processing of the image data.

[0078] In the above-mentioned image data transmission method, through reasonable derivation in combination with the technical features in the embodiments, the following beneficial effects can be achieved to solve the technical problems proposed in the background art:

[0079] This application provides an image data transmission method. The method is implemented based on an image data transmission system. The image data transmission system includes a driving side and a processing side. The method includes: in response to the processing side obtaining the image data to be processed, storing the image data in a predefined memory area; in response to the completion of storing the image data, the processing side generates an interrupt signal and sends it to the driving side; in response to the driving side obtaining the interrupt signal, reading the image data from the memory area; the driving side transmits the obtained image data to the host computer to realize the processing of the image data. In implementation, the above method deletes the unnecessary BAR space register handshake confirmation step in traditional PCIE communication, avoids redundant interaction between the processing side and the driving side, and shortens the delay of data transmission; through the predefined memory area (DMA mapping), direct data interaction between the processing side and the driving side is realized, bypassing the frequent intervention of the CPU, and reducing the overhead of the intermediate link of data transmission. On the other hand, the image data forms a seamless pipeline from acquisition (SICU), processing side, storage (DMA) to the driving side, and each link operates in parallel, shortening the end-to-end processing time; the driving side quickly responds to the interrupt and uploads the data to the host computer, ensuring that the GUI or subsequent analysis module can obtain the latest image data in real time, and enhancing the adaptation effect for scenarios with strict timeliness requirements such as semiconductor detection.

[0080] In one embodiment, as Figure 3 shown, step 204 includes:

[0081] Step 302: Obtain the image data, and based on the association relationship between the image data and the images, determine the target image data associated with the same target image.

[0082] Step 304: Generate the interrupt signal when all of any one of the target image data is stored in the memory area.

[0083] In this embodiment, in the process of image data transmission, when all the data of the entire image is transmitted, an interrupt signal is triggered, which helps to improve the stability of the process and reduce the possibility of transmission anomalies caused by multiple interruptions.

[0084] In one embodiment, as Figure 4 shown, before step 202, it further includes:

[0085] Step 402: The processing side verifies the image data;

[0086] Step 404: If the image data is abnormal, generate abnormal information and store the abnormal information in a predefined status memory.

[0087] In this embodiment, verifying the image data before transmitting it helps improve the stability of image data transmission and handle abnormal situations in a timely manner.

[0088] In one embodiment, as Figure 5 shown, the method includes:

[0089] Step 502: The driving side generates definition information and sends it to the processing side;

[0090] Step 504: The processing side defines the memory area in the memory based on the definition information and the mapping relationship between the processing side and the memory.

[0091] In this embodiment, performing initialization and memory allocation processing before startup enables the transmission, storage, and extraction of image data in a predefined memory area, which helps improve the stability of method implementation.

[0092] In one embodiment, as Figure 6 shown, before step 208, it further includes:

[0093] Step 602: Obtain the data requirements of the application layer and filter the image data;

[0094] Step 604: The driving side transmits the filtered image data to the host computer.

[0095] In this embodiment, filtering the image data before it is transmitted to the application layer helps the image data match the application requirements and improves the stability of image data application processing in the application layer.

[0096] In one embodiment, as Figure 7 shown, the method further includes:

[0097] Step 702: In response to the scan image instruction issued by the host computer, the driving side registers an asynchronous processing function based on a preset processing flow;

[0098] Step 704: The processing side processes the image data based on an asynchronous communication method, and triggers the callback execution of the asynchronous processing function in response to the completion of the transmission of the image data, so that the host computer determines that the image data transmission is completed.

[0099] In this embodiment, processing the transmission of image data based on asynchronous communication helps improve the transmission efficiency.

[0100] In a most specific embodiment, an image data transmission system provided by the present application can be as follows Figure 8 shown. The process of the image data transmission method implemented by applying the image data transmission system as shown in Figure 8 and Figure 9 can be as shown in Figures 10 - 12 shown.

[0101] Specifically by way of example, the specific module composition of the image data transmission system can be as shown in Figure 9 shown, where:

[0102] Clock Domain Sync: The input data and control signals are synchronized to the PCIE clock domain, and flow control logic is embedded to prevent data loss caused by data overflow;

[0103] DMA Engine: The DMA engine includes basic Block DMA transceiver / scheduling / address mapping / 4KB out-of-bounds prevention calculation logic, and is one of the basic component modules for user control and interaction with the BAR space / host computer;

[0104] Reg Space: Stores control / status registers such as DMA and PCIE.

[0105] TX_Req Engine: A control module that actively initiates TLP read / write requests from the user to the RC.

[0106] TX_Cpl Engine: A control module for sending TLP response packets in response to RC requests.

[0107] RX_Req Engine: A control module for receiving BAR space read / write requests initiated by the RC.

[0108] RX_Cpl Engine: A control module for receiving response TLP packets returned in response to requests actively initiated by the user to the RC.

[0109] EP_Logic & High-Speed SerDes: The IP core of the EP.

[0110] Specifically by way of example, the interaction process of the image data transmission method based on the above system can be described as follows:

[0111] First, the driver writes the length / address / dma_start information to the corresponding positions of the BAR0 register of the FPGA; after the FPGA receives the necessary information of length / address / dma_start in sequence, it sets an update signal and then starts the DMA transfer; the FPGA receives an image sent from the SICU, and after the image reception is completed, the FPGA side will check the received image. If there is an error in the image, the error information will be filled into the status register; the FPGA stores the received image information in the memory area mapped during the driver initialization process through the Block DMA mode; after the FPGA successfully transfers an image information to the DDR, it will send an MSI interrupt to the driver.

[0112] Among them, during the device initialization matching process, the mapping relationship between the physical address and the virtual address is obtained using the DMA memory mapping method; when the GUI issues a scan image instruction, the driver sends the parsed length and the pre-allocated and mapped address information to the FPGA; the driver reads the status register of the FPGA to ensure that the status of the FPGA is ready.

[0113] The driver sends the dma_start (DMA start instruction) to the FPGA to start DMA image reception, and then the driver enters the waiting and sleeping state; when the FPGA finishes sending the image and triggers an interrupt, it will wake up the currently sleeping driver thread in the interrupt; the driver reads the image data from the DDR after receiving the interrupt and transfers it to the application layer; the data received by the application layer is the raw data collected by the ADC. After filtering out the highest 4 bits, the lower 12 bits are processed into 1-byte (8-bit) image data and then passed to the GUI for display.

[0114] For the above-mentioned driver-side solution, improvements can also be made in the driver-side implementation plan. The specific implementation plan is as Figure 12 shown. Since the synchronous communication of dma has a large overhead on system resources, in order to ensure faster and more efficient image data transmission, the synchronous communication method of dma is changed to the asynchronous communication method of dma.

[0115] When the GUI issues a scan image instruction, in addition to sending the length and address information to the fpga, the driver side will also register an asynchronous io processing function and notify the kernel that there is an asynchronous io event waiting to be processed;

[0116] After the image transfer is completed, it will trigger the execution of the asynchronous callback function and notify the application layer.

[0117] In an implementation, the asynchronous communication with DMA helps to achieve that there is no need to use the wait / block timeout method to obtain images whether at the application layer or the driver layer. After the image data transmission is completed, the kernel will notify the driver in the way of asynchronous notification, and the driver will then notify the application. This approach can greatly improve the transmission efficiency and is more concise both in terms of code style and DMA transmission behavior.

[0118] Specifically, in the interaction process implemented based on the above image data transmission system in this embodiment, the processing steps of the FPGA in the hardware part can be as follows:

[0119] After all elements required for DMA and control are passed into Reg_Space through Driver_Logic→EP Logic→Rx_Demux→RX_Req_Engine→Reg_Space, the DMA engine control module of the FPGA will retrieve the information of the corresponding register in Reg_Space, start the DMA engine, and wait for the data at the data input end to be transmitted to the DMA engine module after passing through the clock synchronization module. The data will be converted into the TLP format specified by the PCIE 2.0 protocol and sent to the corresponding memory space of the Host PC through TX_Req_Engine→TX_Mux→EPLogic→Driver Logic. At the same time, an MSI interrupt is sent to wake up the software driver and wait for the software driver to execute the next step. In addition, the FPGA logic can also write TX_Cpl_Engine to passively reply with the CPLD packet of the MRD type TLP packet sent by the Host through Rx_Req_Engine. Among them, in order to debug TX_Req_Engine, RX_Cpl_Engine is written to obtain the CPLD packet of the MRD type TLP packet sent by the FPGA to the Host. This helps to improve the overall stability and integrity of the system.

[0120] In the implementation, DMA uses the Block DMA technology, simplifies all necessary elements of SG-DMA, reduces the number of registers that need to be configured between the software driver and the FPGA, further reduces the transmission overhead of the TLP packet carrying configuration information, and thus reduces the time consumption of each DMA start and stop, greatly improving the overall transmission efficiency.

[0121] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are sequentially shown according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times.
