OPERATION METHOD FOR HOST APPARATUS TO SAVE POWER CONSUMPTION

摘要

An operation method for a host apparatus is provided. When a peripheral device connects to the host apparatus through a data transmission interface, the host apparatus is checked whether or not accessing data with the peripheral device. When the host apparatus doesn't access data with the peripheral device continuing a predetermined time, the peripheral device is shut down to make the peripheral device entering a power saving mode from a normal operation mode but an interrupt operation of the data transmission interface is still activated. When the host apparatus need to access data with the peripheral device being in the power saving mode, the interrupt operation is triggered for waking the peripheral device up to revive the peripheral device working under the normal operation mode.
