This invention discloses a low-latency UAV-assisted dynamic distribution method for panoramic video streams based on viewport prediction, belonging to the interdisciplinary field of mobile communication and immersive multimedia transmission. By constructing a multi-level forward-looking virtual queue model, future viewport data requests are mapped to current weighted accumulated potential energy, thereby driving the system to perform traffic temporal shaping when channel conditions are favorable. In other words, through proactive resource scheduling, future transmission tasks are shifted to the present for completion, achieving a proactive service mode for data waiting for users. Simultaneously, in conjunction with a trap-aware hierarchical backtracking optimization strategy, this invention can guide UAVs to actively avoid local optimal deadlocks, ensuring that the optimal air-to-ground transmission link is maintained in dynamic environments, thereby fundamentally eliminating queuing time and guaranteeing a low-latency, smooth playback experience for panoramic video.

The application provides a data processing method for a multi-grain chip and the multi-grain chip, and relates to the chip technical field.The method comprises the following steps: firstly, in response to a computing core of a first grain, a memory access transaction is initiated to a target storage controller of a second grain, and a shared attribute identifier is determined.Then, when the shared attribute identifier indicates that the memory access data is non-shared data, a shunting processing procedure is executed: if it is a write transaction, write request data is split into a control packet and a first data packet, the control packet is sent to the target storage controller through a home agent node, and after a write response is received, the first data packet is sent to the target storage controller through a data path bypassing the home agent node; if it is a read transaction, read request data is sent to the target storage controller through the home agent node, and a second data packet returned by the target storage controller through a data path bypassing the home agent node and a read response returned through the home agent node are received.The scheme can reduce the serialization processing overhead of cross-grain memory access in the multi-grain chip.
