An audio parameter negotiation method and a communication device, the method comprising: a second communication entity negotiates an audio parameter based on an IVAS encoded audio format and an IVAS decoded audio format supported by a first communication entity, and an IVAS encoded audio format and an IVAS decoded audio format supported by the second communication entity; transmitting fifth audio format information indicating at least one fifth audio format and sixth audio format information indicating at least one sixth audio format to the first communication entity, the fifth audio format information indicating at least one fifth audio format, and the sixth audio format information indicating at least one sixth audio format, the fifth audio format is an audio format to be adopted by the first communication entity during IVAS decoding and / or the second communication entity during IVAS encoding, and the sixth audio format is an audio format to be adopted by the first communication entity during IVAS encoding and / or the second communication entity during IVAS decoding. According to the method, the negotiation of the IVAS coding and decoding audio format with finer granularity can be realized.

The application provides an electric light truck urban cruise control method and system, which comprises the following steps: based on a federal learning architecture, the global parameters of an urban traffic cloud platform are updated cooperatively through a federal average algorithm; a working condition characteristic vector library covering global urban roads is constructed according to the global parameters, a migration learning algorithm is used to migrate the speed trajectory planning experience under the historical optimal working condition to the inside of the working condition characteristic vector library, and a source domain-target domain adaptation model is constructed in combination with the remaining battery capacity and power system state of the electric light truck; a speed trajectory initial framework corresponding to the electric light truck is output through the source domain-target domain adaptation model, and a corresponding optimization objective function is constructed according to the speed trajectory initial framework; preset constraint conditions are called out, and the optimal speed trajectory is calculated according to the constraint conditions and the optimization objective function, so that the corresponding urban cruise is completed according to the optimal speed trajectory. The application can effectively improve the cruise control efficiency of the electric light truck.

The application provides a method, device, storage medium and program product for improving RDMA dual-card switching efficiency, and belongs to the technical field of computer networks, and comprises the following steps: intercepting RDMA calling of an application program through a self-provided RDMA function library of an intermediate library; when the RDMA calling is intercepted, responding to the RDMA calling through the self-provided RDMA function library to perform RDMA communication, mapping resources required by the RDMA communication into resources of the intermediate library so that the application program directly accesses the resources of the intermediate library; standby resource preparation and pre-association; monitoring changes of RDMA network cards through the intermediate library, and when a failure of a main RDMA network card is monitored, the next step is entered; a failure signal and complete association of the standby resource; after the complete association is successfully completed, the resources of the intermediate library of the associated main RDMA network card are switched to the associated standby RDMA network card to continue the RDMA communication. The method further reduces the RDMA network card failure switching time.

The present application provides a data transmission method based on FPGA, wherein the FPGA includes a PL end and a PS end, wherein the PL end collects data through a FIFO buffer ADC and transmits the data to the PS end, and the PS end transmits the data to a host computer through a network port; data transmission is performed between the PL end and the PS end based on CDMA, and is applied to a lower computer including a state machine for controlling a CDMA data transmission process; the state machine includes an idle state, an interrupt waiting state, a CDMA data transmission, a network port data return, and a transmission end state; the method includes cycling through an idle state and an interrupt waiting state before an interrupt is generated, responding to an interrupt to enter a CDMA data transmission state, switching to a network port data return state after completing data movement, and entering a transmission end state to perform a reset after all transmissions are completed. The present application can improve data transmission efficiency and ensure the stability of data transmission from a program perspective.
