A method and an apparatus for managing power of a Wireless Local Area Network (WLAN) module in a portable terminal are provided. In the method, the WLAN module is operated according to a Power Save Mechanism (PSM). Whether the portable terminal operates in a sleep state is determined. At least one of a beacon interval and a Delivery Traffic Indication Map (DTIM) interval of the PSM is changed depending on whether the portable terminal operates in the sleep state.

Provided is an apparatus and method for saving power in a dual mode portable terminal that concurrently supports a cellular network and an unlicensed band network. The method includes, upon disassociating from an in-association Access Point (AP) of an unlicensed band network, measuring a Received Signal Strength Indicator (RSSI) from the AP during a predetermined time and calculating an average value of the RSSI; and comparing the calculated average value with a predetermined threshold value and deciding whether to perform a mode conversion between a low power mode and a general mode.

An apparatus and a method for processing high speed data using hybrid Direct Memory Access (DMA) are provided. The method includes determining a size of data to be transmitted, determining a memory access method of the data by comparing the determined size of the data with a first threshold, and determining an I/O bus access method of the data by comparing the determined size of the data with a second threshold.
