Abstract:
The method manages the same data duplex in the disk memory region not to affect disordering or losing some data so that either of the duplex data provides high availability. The method is arranged that: the start and stop of mirror disk implementation is informed through a mirror commander (3) an then a mirror disk driver (4) controls a mirror disk table (5) related to the mirrored disk and in the case of starting, and demands duplex writing and optimal reading to the I/O processor in order to obtain duplex copy in the disk (8) through the disk controller (7); otherwise, it separates the duplex relationship.
Abstract:

CONSTITUTION: A process unit(121) transmits and receives information by an L3 terminal(110) and a gigabit ethernet port. A baseband modem unit(123) modulates or demodulates information that the process unit receives using 64 QAM(Quadrature Amplitude modulation) into a digital signal. A frequency conversion unit(125) converts the digital signal into an analog signal of 20MHz bandwidth. The frequency conversion unit transmits the analog signal by a plurality of multiple antennas.
Abstract:
PURPOSE: A turbo decoder and a turbo decoding method are provided to improve the processing speed of the whole CODEC system by reducing the delay time of the delay time between the code block and the turbo decoding itself. CONSTITUTION: Sub block division parts(210, 310) divide the turbo-coded code block into the sub block of m. Turbo engines of m turbo-decode each sub block. Sub turbo-sub block synapses(230, 330) output the turbo-decoded code block. A memory(400) stores the turbo-coded transport block encoded turbo. A code block division part(101) divides the transport block stored in the memory into a plurality of code blocks.
Abstract:
A transmission method for a data rate matching and an apparatus thereof are provided to prevent a punch for data having a high weight value by performing efficient data rate matching based on a variably allocated resource. A transmission method for a data rate matching includes the steps of: receiving a coded input signal based on a predetermined coding rate(S100), and segmenting the received input signal into a systematic bit and a plurality of parity bits based on the coding rate(S110); matching the parity bits based on a size of a received buffer(S120); performing a data rate matching for the parity bits and the systematic bit based on resource information for a physical channel allocated on an input signal and information for a resource which is additionally punched (S130,S140); and integrating the systematic bit and the parity bits which are matched in the second matching step(S150).

Packet calls corresponding to the packet services are divided by connecting the first, second and third delimiters.
Abstract:
PURPOSE: A USB(Universal Serial Bus) drive method, and an embedded system adopting the method are provided to efficiently set an I/O scheme of a USB device at a user application program layer, and to minimize a code and a program size to be considered in an embedded system with limited resources. CONSTITUTION: A user application program enables a user to select an I/O scheme of a USB device, e.g a DMA(Direct Memory Access) scheme or a programmable scheme by using a standard I/O function of an OS(S10). An I/O control block within a USB device driver analyses parameters to be transferred simultaneously with the standard I/O function when the standard I/O function is called, checks whether a USB device related I/O request is transmitted(S20), and then analyses the parameters included in the standard I/O function(S30). In a case that the requested I/O scheme is set at a DMA scheme, the I/O control block sets a call back table of a DMA I/O scheme(S50). In a case that the requested I/O scheme is set at a programmable I/O scheme or a CPU bound I/O scheme, the I/O control block sets a call back table of a programmable I/O scheme(S60).
