Abstract: The present invention provides an electronic device including a plurality of processing circuits is disclosed, wherein the apparatus includes a circuitry configured to perform the steps of: receiving a model an input data for execution; analyzing the model to obtain a graph partition size of the model; partitioning the model into a plurality of graphs based on the graph partition size, wherein each of the graphs comprises a portion of operations of the model; deploying the plurality of graphs to at least two of the processing circuits, respectively; and generating output data according to results of the at least two of the processing circuits executing the plurality of graphs.

Abstract: A multi-screen synchronized playback system including a group, a network time protocol (NTP) server is provided. The group includes a plurality of playback devices connected to a local area network (LAN). One of the playback devices is designated as a master playback device, the remaining playback devices of the playback devices are designated as slave playback devices. The NTP server is connected to the LAN and provides a standard time information for each of the playback devices. In preparing state, the master playback device sends a first type packet to each of the slave playback devices through the local area network, and the first type packet includes a starting playback time information according to the standard time information provided by the NTP server. A multi-screen synchronized playback method is also provided.
