Abstract
A sub-circuit configuration allowing an external device access to a storage device provided at the host through configuration of a sub-circuit is separated using a power controller from a main circuit configuration in portable electronic device; the power controller being related to a power supply loop to switch among circuit configurations of a main system and its subsystems, and the connection among components of the main and the sub-circuit configurations.
Claims5
A sub-circuit configuration in a portable electronic device to access to a storage device in a portable electronic device with the electronic device in power on or power off status, comprising:
- a sub-circuit configuration segregated with a power controller from a main circuit configuration containing a microprocessor and a storage device;
- and the power controller being provided to switch a power supply loop of the main circuit configuration and/or the sub-circuit configuration, and controls the connection among components between the sub-circuit configuration and the main circuit configuration,
- wherein the main circuit configuration is integrated with at least one first device selected from a first group consisting of an encoder and sound effect output port;
- and the sub-circuit configuration has a decoder and a memory,
- wherein the power controller is comprised of one or multiple electronic switches,
- wherein the sub-circuit configuration is further integrated with a wireless transmission modulus, the decoder of the sub-circuit configuration is connected to the memory and the wireless transmission modulus thereof,
- wherein the wireless transmission modulus connected to the decoder if the sub-circuit configuration is a Bluetooth wireless transmission.
