AI Technical Summary
Technical Problem
Existing System Power Management Interface (SPMI) protocols struggle to effectively address and transmit large amounts of data when dealing with emerging use cases such as multi-core processors, leading to increased latency and performance degradation.
Method used
By extending the functionality of datagrams, addressing options are added to support more than four master devices, and the address and payload format of datagrams are modified to allow simultaneous broadcasting of datagrams, thereby improving data transmission efficiency.
Benefits of technology
It reduces latency, improves the overall performance of the SPMI system, and adapts to the needs of complex systems such as multi-core processors.

Abstract
系统电源管理接口(SPMI)系统中的扩展功能数据报允许从设备使用扩展功能数据报来寻址与SPMI系统相关联的大量主设备(例如，4个以上)。此外，寻址可以允许数据报被同时广播到多个主设备。此外，通过发信号通知主设备寻址不同于标准的SPMI格式，数据报的地址和有效载荷的性质可以变化，以处理比SPMI标准平常允许的更大的数据量。
