It supports the latest version (v2.0) of the MIPI-SPMI specification, and is suitable for the implementation of either master or slave nodes in an SPMI bus. The core is designed to minimize the software load on the host processor. Once configured,
The MIPI System Power Management Interface, MIPI SPMI℠, specifies the hardware interface between baseband or application processors and peripheral components to support advanced power management techniques. The specification also reduces design costs and shortens time to market of mobile devices by simplifying the interconnection of devices
could be negatively affected by the BIOSconfigured power management settings, causing systems to go to sleep during presentations or other inconvenient times. Second, the power management interface was proprietary on each system. This required developers to learn how to configure power management for each individual system. Finally, the
SPMI is the short form of System Power Management Interface. The specifications of SPMI are defined and managed by MIPI Alliance. It is 2 wire bi-directional interface with lines SDATA and SCLK. It supports multi-master and multi-slave configurations. In this protocol, Slaves work in two modes viz. request capable and non-request capable.
Interface management is classified as an SE technical management process. As such, the interface management process provides a framework to identify, define, manage and ensure compliance with internal and external system interfaces. The interface management process helps ensure that developers capture all internal and external interface
