Abstract
An electronic device includes a first CPU, a second CPU, an auxiliary storage unit, and a controller. The auxiliary storage unit includes a first starting program for the first CPU and a second starting program for the second CPU. The first CPU loads the first starting program via the controller, and causes the controller to load the second starting program in DMA transfer. The controller, if the controller is caused by the first CPU to transfer part of the first starting program while the controller is loading the second starting program, stops loading the second starting program. When completing the transfer of the part of the first starting program, the controller restarts loading the second starting program.
