AI Technical Summary
In multi-device connection scenarios, existing technologies face challenges in wiring between devices, resulting in high costs, system stability, and flexibility. This is especially true in in-vehicle multimedia systems, where the number of devices increases linearly, leading to a rise in the number and weight of connecting cables. Furthermore, communication between device nodes is highly dependent on the control node, which can easily cause line conflicts and system paralysis.
A daisy-chain topology is used to connect multiple nodes through a single bus. The bus transmits data in frames, which contain downlink and uplink subframes. Nodes process data autonomously by transmitting configuration information, reducing the amount of wiring and enabling bidirectional data transmission within each frame. Nodes can operate normally without processor intervention.
It effectively reduces the number and cost of wiring between devices, improves data transmission efficiency, enhances system flexibility and stability, reduces system weight, and maintains normal system operation without processor intervention.
