This invention discloses a graphics processing unit (GPU), a task execution method, an electronic device, and a storage medium. The GPU includes at least a filtering calculation unit, an execution unit, a first data loading unit, and a second data loading unit. The first data loading unit loads execution data for a first filtering task and stores the execution data in a first buffer. The second data loading unit loads execution data for a second filtering task and stores the execution data in a second buffer. The execution unit filters target execution data that meets the full-load condition of the filtering calculation unit from the first and second buffers and transmits the target execution data to the filtering calculation unit. The filtering calculation unit performs filtering calculations on the target execution data. This invention maximizes the bandwidth utilization of the filtering calculation unit and improves the execution efficiency of the GPU's filtering tasks.

An adaptive link management method and system based on satellite mobile communication employs a PPP-based UDP protocol for initial link negotiation. Network address and other information are exchanged through link establishment request and confirmation signaling interactions. Network segment relationships are determined based on address information: GRE encapsulation with proxy ARP assistance is used for same network segments, while standard GRE encapsulation is used for different network segments. Link endpoint identifiers are negotiated and a bidirectional transmission link is established under the selected encapsulation mode. After link establishment, both parties periodically exchange keep-alive signaling to maintain connectivity. Simultaneously, the status of connected local access devices is monitored, and information is synchronized according to a preset period and / or status changes to dynamically update the transmission path and perform IP address conflict detection and handling. The transmission link is released normally through link release signaling. This scheme improves link adaptability and bandwidth utilization, effectively prevents address conflicts, and thus enhances network reliability.

The application belongs to the field of data security, and particularly relates to a multi-modal secure data transmission method and system based on differentiated code rate allocation. The method decouples the synchronously collected multi-modal data stream into a semantic primitive sequence, evaluates the semantic influence factors of each mode through a proxy model mask aligned with the backend secure recognition large model task, and extracts a task attention coefficient from the attention weight of the large model to generate a transmission importance coefficient. When the network bandwidth is limited and the time delay is high, the first deep compression strategy is performed on the lowest importance mode according to the transmission importance coefficient, the semantic redundant area is identified and compressed through cross entropy comparison for the high importance mode, and finally, the compressed data packet is added with a semantic label and a cross-modal identifier for priority queue scheduling and retransmission control, so as to maximize the secure recognition semantic throughput.

This invention discloses a SATA command acceleration system and method. The system includes a command queue, a DMA queue, a submission unit, a hardware resource management unit, and a DMA status queue, used to record the status of DMA tasks completed by the DMA engine. The firmware periodically processes commands in the command queue to configure corresponding DMA task descriptors in the DMA queue, and periodically queries the DMA status queue to determine the completion status of SATA commands. Thus, through hardware-coordinated management of the command, DMA, and status queues, the system reduces the real-time DMA transfer management task of the firmware, achieving automation and pipelined DMA transfer, thereby significantly reducing CPU load and improving data transfer efficiency and system response speed. It reduces firmware intervention in the SATA command transfer process, lowering CPU load; and through queuing and automation mechanisms, it achieves seamless DMA transfer, maximizing bus bandwidth utilization.
