When a single upper application has only one event, the embedded programmable chip corresponding to the upper application inputting the event can perform the calculation processing of the event, and when a certain upper application has one event being processed, if the same upper application generates a new event processing request, the computing capability of the embedded programmable chip of the upper application may be insufficient.
Specifically, after the event processing device receives the event to be processed, the event to be processed is split into at least one process task, where a single event may include multiple process tasks, as shown in table 1, a VoIP/VoLTE (Voice over Internet Protocol/Voice over Long-Term event) video call event may be split into process tasks such as camera acquisition signal processing, video compression, audio processing, image processing, and the FLV (FLASH VIDEO) video play event may be split into process tasks such as video compression, audio processing, and image processing. When splitting an event to be processed into at least one process task, assigning a task ID to each process task, for example, the task ID of the camera acquisition signal processing process task in the event task1 in table 1 is task1.1. When splitting the event to be processed into at least one process task, a routing ID of each process task is also determined, specifically, the routing ID of the process task is used to determine a transmission path of the process task, i.e. how the process task is transmitted to the corresponding proxy service. The routing ID of the process task may be determined according to a preset correspondence.
