An apparatus for fast booting based on a virtualization technique includes: a hardware comprising a processor, a memory and a storage where a status information corresponding to an operating system (OS) is stored; and a virtual machine monitor (VMM) for interfacing between the OS and the hardware, wherein the VMM is operated by the processor and loads the status information on the memory. Herein, the status information may be pre-generated to include data in the memory in a state where the OS is completely booted.

A multi-pointing method using a magnetic field is provided. When one or more pointing devices that generate magnetic fields move or rotate, locations and directions of rotation of the one or more pointing devices are sensed based on patterns of magnetic fields generated by the one or more pointing devices and changes in the patterns.

A data transmitting method of simultaneously reproducing a plurality of moving picture contents includes: encoding a plurality of moving picture contents into a single moving picture content; and transmitting the encoded moving picture content. The data transmitting method further includes receiving play list information for specifying the plurality of moving pictures contents that are to be simultaneously reproduced before the decoding, wherein, in the encoding, the plurality of moving picture contents specified by the received play list information are encoded into a single moving picture content.

A duty cycle correction (DCC) circuit and a delayed locked loop (DLL) circuit using the same are disclosed. The DCC circuit is operated by an enable signal which is enabled when the DLL is locked. The duty cycle correction (DCC) circuit includes a clock input unit and a duty cycle mixing unit. The clock input unit receives the enable signal and first and second clock input signals having opposite phases, generates an inverting signal of the first clock input signal, and when the enable signal is enabled, generates first and second internal clock signals, based on the first and second clock input signals and the inverting signal. The duty cycle mixing unit mixes a phase of the first internal clock signal with a phase of the second internal clock signal.

Spin-coating apparatus for use in manufacturing a semiconductor device or the like and a method of operation of the apparatus prevent substrates from being positioned incorrectly in a process module of the apparatus. The spin-coating apparatus includes an image sensor that captures an image of the wafer in the process module, and a control unit that receives image data from the image sensor. The method includes loading a substrate onto a process module using an arm of a transfer device, capturing an image of the substrate using the image sensor, and comparing image data generated by the image sensor with a standard image data stored to determine an actual position of the substrate. If the substrate is incorrectly positioned, the operation of the arm of the transfer device is adjusted to compensate.

A method for constructing and searching an improved Huffman table which is capable of improving the efficiency over an existing Huffman table in a decoding method and apparatus using a Huffman code. The method includes creating an improved Huffman table including an increment of a Huffman code length and the number of times Huffman code lengths repeats; generating a new bit string by extracting bits by the increment of the Huffman code length and adding the extracted bits to the end of a previous bit string; and reading values of corresponding codes by the number of times Huffman code length repeats from the improved Huffman table and determining whether values identical to a value of the new bit string are present. According to the present invention, unnecessary consumption of system resources can be reduced by decreasing the number of times search and comparison routines of Huffman codes are used.

A method for processing various numbers of ports in a network processor. A method for processing various numbers of ports in a network processor comprises the steps of: a) receiving the number N of ports from a system controller; b) allocating N−1 number of registers for storing N−1 number of port management information in response to the number N of ports; c) processing a packet by sequentially accessing the N number of ports; and d) after processing a packet related to a predetermined port, storing management information related to the predetermined port in a register used for the next port, and storing the management information related to the predetermined port in a first register among the N−1 number of registers when a register for storing management information in a previous packet processing is the last (N−1)-th register among the N−1 number of registers.

The present invention relates to a semiconductor laser, having a construction capable of tuning a wavelength, in which a sampled grating distributed feedback SG-DFB structure portion and a sampled grating distributed Bragg reflector SG-DBR structure portion are integrated. In the present invention, the refraction index are varied in accordance with a current applied to the phase control area in the SG-DFB structure portion and the SG-DBR structure portion, whereby it is possible to continuously or discontinuously tune the wavelength. Therefore, in such a wavelength tunable semiconductor laser, its construction is relatively simple, and it is relatively useful to the manufacturing and mass-producing the semiconductor laser. In addition, such a wavelength tunable semiconductor laser has an excellent output optical efficiency while making it possible to tune the wavelength of the wide band.
