DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

Referring to FIG. 1 , FIG. 1 is a structural block diagram of a data transmission system in an embodiment of the present application, and the system may include:

A complex programmable logic device 1 is used to monitor the network status between the cloud server and the central processor in the edge device; when it is determined that the network status is that the network module is blocked, a first network switching instruction is sent to the improved internal integrated circuit multiplexer 2; receiving the data to be cached sent by the central processor through the improved internal integrated circuit bus, and sending the data to be cached to the data buffer 3; when it is monitored that the network status changes from the network module being blocked to the network being normal, a second network switching instruction is sent to the improved internal integrated circuit multiplexer 2; the cached data in the data buffer 3 is read, and the cached data is uploaded to the cloud server through the improved internal integrated circuit bus;

The improved internal integrated circuit multiplexer 2 is used to switch the central processing unit from being connected to the cloud server to being connected to the complex programmable logic device 1 according to the first network switching instruction; and to switch the central processing unit from being connected to the complex programmable logic device 1 to being connected to the cloud server according to the second network switching instruction, so that the central processing unit uploads data to the cloud server through the network module;

The data buffer 3 is used to buffer the data to be buffered.

The data transmission system provided in the embodiment of the present application includes a complex programmable logic device 1 (Complex Programmable Logic Device, CPLD), an improved inter-integrated circuit multiplexer 2 (Improved Inter-Integrated Circuit Multiplexe, I3C MUX) and a data buffer 3. The network status between the cloud server and the central processing unit (Central Processing Unit, CPU) in the edge device is monitored by the complex programmable logic device 1. When it is determined that the network status is that the network module is blocked, a first network switching instruction is sent to the improved internal integrated circuit multiplexer 2. The improved internal integrated circuit multiplexer 2 switches the central processing unit from being connected to the cloud server to being connected to the complex programmable logic device 1 according to the first network switching instruction. The complex programmable logic device 1 controls the improved internal integrated circuit multiplexer 2 to receive the data to be cached sent by the central processing unit through the improved internal integrated circuit bus, and sends the data to be cached to the data buffer 3, and the data buffer 3 caches the data to be cached.

When the complex programmable logic device 1 detects that the network status has changed from network module congestion to network normality, it sends a second network switching instruction to the improved internal integrated circuit multiplexer 2, reads the cached data in the data buffer 3, and uploads the cached data to the cloud server through the improved internal integrated circuit bus. The improved internal integrated circuit multiplexer 2 switches the central processing unit from being connected to the complex programmable logic device 1 to being connected to the cloud server according to the second network switching instruction, so that the central processing unit can upload data to the cloud server through the network module. This achieves that the data cached in the data buffer 3 and the newly generated data of the central processing unit are uploaded to the cloud server in parallel.

Compared to a microcontroller unit, the complex programmable logic device 1 has a basic programmable structure that enables users to quickly program to perform corresponding functions. In addition, the complex programmable logic device 1 can perform multiple logical operations in parallel, significantly improving computing efficiency. The complex programmable logic device 1 can also support a wider data bus width (more than 16 bits) for interfacing with external memories, which makes it very suitable for bus interfaces and protocol bridging applications. The complex programmable logic device 1 also allows precise control of timing logic, making it more suitable for server and other needs. The embodiment of the present application improves the efficiency of edge computing devices by dynamically allocating resources using a complex programmable logic device 1, solving the pain points of intermittent connections, disconnections and delays, robust error handling, and efficient power management in edge environments.

In areas such as servers where data integrity is critical, additional mechanisms need to be implemented at the application level. As an enhanced version of the Inter-Integrated Circuit (I2C), the improved inter-integrated circuit multiplexer combines the functions of the inter-integrated circuit, the serial peripheral interface (SPI) and the universal asynchronous receiver/transmitter (UART) to support synchronous and asynchronous communication. In certain modes (such as HDR-BT mode), it can support the cyclic redundancy check (CRC) function at a high rate.

The edge device acts as an intermediary between the local device and the cloud server. To ensure seamless synchronization, the edge cloud synchronization buffer (i.e., data buffer 3) plays a vital role, temporarily storing data before transmitting it to the cloud, and using complex programmable logic devices 1 to verify the correctness of this data. By aggregating data from multiple terminals and sending data in larger blocks, edge devices reduce communication overhead.

It can be seen from the above technical solution that by connecting the complex programmable logic device with the central processing unit, data buffer, etc. in the edge device, and using the improved internal integrated circuit bus for signal transmission between the central processing unit and the complex programmable logic device, the advantages of the improved internal integrated circuit bus, such as high data transmission rate, low power consumption, and fewer cables, are fully utilized. The use of complex programmable logic devices to realize network edge processing data caching fully utilizes the advantages of complex programmable logic devices such as being able to perform multiple logical operations in parallel, supporting wider data bus widths, and allowing precise control of timing logic, thereby achieving adaptive perception of edge server resources, good scalability, and improved data caching efficiency.

It should be noted that, based on the above embodiments, the embodiments of the present application also provide corresponding improved solutions. In the subsequent embodiments, the same steps or corresponding steps as those in the above embodiments can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be repeated one by one in the following improved embodiments.

In a specific implementation of the present application, the data buffer 3 is a flash memory chip 31 set including at least two flash memory chips 31 .

See Figure 2, which is a topological diagram of a complex programmable logic device 1 edge cloud synchronization buffer system in an embodiment of the present application. The data buffer 3 for caching the cached data can be set to a flash memory chip 31 set including at least two flash memory chips 31. By using the flash memory chip 31 as a high-speed cache for storing frequently accessed data, an efficient synchronization buffer is established, bridging the gap between the edge device and the cloud server, and improving the data cache efficiency.

The embodiment of the present application provides an edge computing device architecture including a complex programmable logic device 1, which is a heterogeneous multi-core architecture. The complex programmable logic device 1 is combined with a system-level chip, a flash memory chip 31, etc., and an improved internal integrated circuit bus with a cyclic redundancy check is used. The complex programmable logic device 1 is used for real-time control and data management verification, and the flash memory chip 31 data cache is implemented to reduce the delay in the data transmission process. The embodiment of the present application can monitor and control peripheral signals and redundant improved internal integrated circuit buses in a simple, cost-effective way. Users can easily add additional I/O (Input/Output) to the design, thereby freeing up the GPIO (General Purpose Input/Output) of devices such as the central processing unit for other more important functions.

In a specific implementation of the present application, the complex programmable logic device 1 is also used to roll back to a pre-stored verified firmware version when it is determined that the current new firmware version has an error.

See Figure 3, which is another topology diagram of the edge cloud synchronization buffer system of the complex programmable logic device 1 in the embodiment of the present application. Multiple firmware versions of the complex programmable logic device 1 are maintained in advance in the complex programmable logic device 1 firmware flash memory chip 31 (CPLD Firmware FLASH), and the complex programmable logic device 1 is also used to roll back to the pre-stored verified firmware version when it is determined that there is an error in the current new firmware version. By setting the firmware version rollback strategy, the fault-tolerant setting of the complex programmable logic device 1 firmware version is realized, and the reliability of the operation of the complex programmable logic device 1 is improved.

In a specific embodiment of the present application, the system may further include a central processing unit load sensor 4 disposed between the central processing unit and the complex programmable logic device 1, the central processing unit load sensor 4 being used to detect the load state of the central processing unit and obtain a load state detection result;

The complex programmable logic device 1 is also used to adjust the voltage and clock frequency of the central processing unit according to the load state detection result.

Refer to Figure 4, which is a topological diagram of the resource and power management system of the complex programmable logic device 1 in the embodiment of the present application. The data transmission system provided in the embodiment of the present application may also include a central processing unit load sensor 4 (such as a utilization counter) arranged between the central processing unit and the complex programmable logic device 1. The central processing unit load sensor 4 is used to collect real-time data to detect the load state of the central processing unit and obtain a load state detection result. The complex programmable logic device 1 is also used to adjust the voltage and clock frequency of the central processing unit according to the load state detection result. During heavy loads, the voltage and clock frequency are increased to obtain better performance. During light loads, the voltage and clock frequency are reduced to save power. During sleep, the power supply of the power supply chip related to the central processing unit is turned off to reduce power consumption during idle periods and maximize power saving, thereby achieving fine-tuning of performance without affecting efficiency.

In a specific implementation of the present application, the complex programmable logic device 1 is specifically used to control the power supply chip of the central processing unit to shut down when it is determined that the central processing unit is in a sleep state according to a load state detection result.

The CPU operating modes include Normal, Idle, and Sleep. In normal operation, the CPU is fully enabled, the device is fully powered and receives active clocks. In Idle mode, all CPU clocks are stopped, and only the clocks to the peripherals are active, even if the CPU and other components are powered. In Sleep mode, power to the CPU and other peripheral components is disabled. Sleep mode disables all functions except the real-time clock, interrupt controller, power manager, and general-purpose I/O.

Efficient resource and power management in edge devices is critical. Dynamic Voltage and Frequency Scaling (DVFS) adjusts CPU performance based on workload. Sleep mode reduces power consumption during idle periods. By balancing performance and energy use, edge devices can maximize their operational lifespan.

The complex programmable logic device 1 is specifically used for controlling the power supply chip of the central processing unit to shut down when it is determined that the central processing unit is in a sleep state according to the load state detection result, thereby reducing the power consumption during the idle period.

In a specific implementation of the present application, the complex programmable logic device 1 is specifically used to verify the data to be cached, and when the verification passes, the data to be cached is sent to the data buffer 3.

The complex programmable logic device 1 is specifically used to verify the data to be cached, and when the verification passes, the data to be cached is sent to the data buffer 3. Robust error detection mechanisms, such as cyclic redundancy check (CRC) and parity check bits, identify damaged data during transmission. In the embodiment of the present application, the improved internal integrated circuit bus uses HDR-BT HDR Bulk Transport Mode, HDR bulk transmission mode), so that the complex programmable logic device 1 verifies to the central processor whether the transmission cyclic redundancy check value of each information frame is consistent with the cyclic redundancy check value calculated from the received data. The central processor can determine through the cyclic redundancy check whether the buffer can be released and continue to send information to the complex programmable logic device 1, or whether the data must be resent, which can prevent data corruption and enhance system reliability.

The complex programmable logic device 1 is specifically used to obtain the data size of the data to be cached and the remaining storage space size of the data cache 3. When it is determined that the data size is greater than the remaining storage space size, the data to be deleted is screened from the data cache 3 and the data to be deleted is deleted. That is, the complex programmable logic device 1 stores the received and verified data in the flash memory storage chip 31. The number and size of the flash memory storage chip 31 can be flexibly configured according to the actual redundancy requirements and the size of the information to be stored based on the network situation. When the storage file format exceeds the size that the flash memory storage chip 31 can accommodate, the oldest data is replaced with the latest data. By deleting the cached data in the data cache 3 in a timely manner, the smooth caching of subsequent data is ensured, data loss is avoided, and data reliability is improved. When network congestion occurs, critical data is given priority. If the flash memory storage chip 31 is limited, the less critical data is discarded, or the oldest data is replaced with the latest data. When the network is restored and the old data transmission is completed, the circular buffer is cleared to efficiently manage the storage.

Edge devices must be able to withstand hardware failures without interrupting service, and redundancy and fault tolerance are key. Dual power supplies, mirrored storage, and redundant network paths ensure continuity. If a component fails, the system will seamlessly switch to backup resources. The following designs can be used in the architecture of the embodiment of the present application to achieve fault-tolerant hardware recovery effects:

Redundant components (such as multiple flash memory chips 31) are used to minimize the impact of single point failures.

Implement data replication: store data in multiple locations (primary flash memory chip 31 and backup flash memory chip 31) simultaneously.

As shown in FIG3 , a watchdog timer is integrated in the CPLD 1. If the CPLD 1 stops responding (due to a fault), the watchdog timer will trigger a reset. At this time, the improved internal integrated circuit multiplexer 2 is fixedly switched between the central processor and the network module to ensure that the CPLD 1 can fully operate even if it hangs.

Monitor the operating status of the complex programmable logic device 1, the flash memory chip 31, and the network. Set up alarms for abnormal situations (e.g., SNMP traps, email notifications). Take proactive measures based on the alarms (e.g., switch to backup components).

Maintain multiple firmware versions of complex programmable logic devices 1, such as setting a fixed CPLD FirmwareFLASH and rolling back to a known stable version if a new version causes problems.

The design allows for seamless switchover to the redundant component if one component fails.

In a specific embodiment of the present application, the system may further include:

The cooling device is used to cool down the complex programmable logic device 1 when it is sensed that the operating temperature of the complex programmable logic device 1 exceeds a preset value.

See Figure 5, which is a topological diagram of another CPLD 1 edge cloud synchronization buffer system in an embodiment of the present application. The data transmission system provided in the embodiment of the present application may also include a cooling device, such as a cooling device that can be configured as a fan 5 connected to the CPLD 1. When the cooling device senses that the operating temperature of the CPLD 1 exceeds a preset value, the CPLD 1 is cooled, and thermal management optimization is achieved through the intelligent cooling device.

By selecting a suitable complex programmable logic device 1 with sufficient I/O pins and logic resources, and using hardware description languages (Hardware Description Language, HDL) such as VHDL (Very High Speed Integrated Circuit Hardware Description Language) or Verilog to develop the logic of the complex programmable logic device 1, it can play the following roles:

Acts as a central controller to manage data flows between edge devices and cloud servers.

Implement a cyclic redundancy check or other error checking mechanism.

Optimize power usage and resource allocation based on server computing tasks.

When the complex programmable logic device 1 detects that the network is stuck for a long time, only critical data is written to the flash memory chip 31, and the power supply of the central processing unit is reduced according to the strategy.

According to the above system architecture, the edge server latency can be minimized while achieving a good balance between performance and energy efficiency, which can be used in common edge device application scenarios. By connecting the complex programmable logic device 1 with the central processing unit, flash memory chip 31, power supply and other modules, using improved internal integrated circuit bus, universal asynchronous receiver and transmitter and other buses for signal transmission, using complex programmable logic device 1 to achieve fine-grained resource allocation, using predictive pre-fetch transmission scheme to reduce data retrieval latency, improve fault-tolerant recovery mechanism and enhance system reliability. The completion of this solution can greatly solve the needs of edge device resource perception adaptation, prediction strategy, robust error handling and efficient power management, and the BOM (Bill of Materials) increase is small, scalability is good, and it is very suitable for edge computing application scenarios.
