An electronic apparatus includes an initializing unit configured to, at power-on, execute in parallel a process of initializing data, which is stored in a first nonvolatile memory and requires initialization, into a first volatile memory by a first microprocessor unit and a process of initializing data, which is stored in a second nonvolatile memory and requires initialization, into a second volatile memory by a second microprocessor unit, and to copy a second set of initialized data, which has been initialized by the second microprocessor unit and stored in the second volatile memory, into the first volatile memory via the communication interface. A startup time of the electronic apparatus is shortened.
