  • Publication number: 20190286609
    Abstract: An electronic device includes plural modules; a return factor detection unit that detects a return factor causing return from an energy-saving state; and a return controller that causes the plural modules to start return processing upon detection of the return factor by the return factor detection unit. The plural modules include a first module and a second module that are connected by using a high-speed serial interface that needs preprocessing for establishment of connection without software, and the second module, which performs return processing upon receipt of a trigger of return from an energy-saving state through the first module, starts the preprocessing for establishment of connection using the high-speed serial interface in parallel with return processing of the first module.
