Abstract: Provided are a method and apparatus capable of reducing a metadata processing time associated with address mapping performed to input/output burst data at a high speed in a virtual file system of a storage unit having a plurality of non-volatile data storage media. The method includes: determining a block group including a block included in each of a plurality of the non-volatile data storage media; determining an access unit including each page included in the determined block group; and mapping an address of input/output data to the determined block group and the access unit. Therefore, it is possible to significantly reduce an address mapping processing time in the virtual file system that may function as a bottleneck in high-speed input/output in a large-capacity storage unit.

Abstract: Disclosed is an apparatus and a method for improving the receive (Rx) sensitivity of a portable Radio Frequency IDentification (RFID). The portable RFID reader/writer is equipped with a variable phase shifter which is connected between an antenna and a directional coupler and then changes an impedance in the direction of the antenna in response to controlling a phase shift, a level of a reflection signal if a transmit (Tx) signal of the portable RFID reader/writer reflected by the antenna flows into an Rx path is measured, and then the phase shift of the variable phase shifter is controlled in such a manner as to minimize the measured level of the reflection signal. Therefore, calibration is implemented so that an antenna impedance changing in response to a position in which contact is made by a user's hand may have an adaptively optimal antenna reflection coefficient, thereby improving the Rx sensitivity.

Abstract: A command scheduling method and apparatus for reducing the complexity of a virtual file system embodied in a nonvolatile data storage device and performing efficient interleaving by setting a preparation phase of a command schedule in the virtual file system embodied in the nonvolatile data storage device is provided. The method includes setting a preparation phase in which a plurality of metadata commands for data management are executed, and if the plurality of metadata commands are completely executed in the preparation phase, executing data read/write commands. Accordingly, by simplifying the scheduling structure of the virtual file system (FTL), code size and resource use can be reduced. In addition, by performing exact interleaving, burst data transmission between a host and a memory storage device can be achieved even without using a large capacity buffer.
