摘要： A method of data placement and control in a block-divided distributed disk array is provided. At first, data to store is divided into logical blocks, and each of the divided logical blocks is further divided into a plurality of data blocks. Then, a parity block is created through performing an XOR operation on the data blocks of each logical block in a unit of a strip, and the parity block is arranged at the first block of a strip unit. Then, parity blocks are arranged at a next block of a previous logical block's the last data block through a left/right shifting for uniformly arranging the parity blocks through out all disks in order to fill an empty block between the logical blocks.

摘要： Disclosed is a method for embedding and extracting a spatial domain blind watermark using a sample expansion. The sample expansion method using a sample expansion coefficient is introduced to basically improve a common disadvantage of the conventional watermarking method based on the patchwork method, for instance, the watermark is not robust against a compression attack such as JPEG. By applying the sample expansion to a sample group, the embedded watermark comes to contain a low frequency component more larger than ever, so that radio frequency component decreases as much. Thus, although the radio frequency component of the watermark is damaged by the image compression such as JPEG, it is possible to relatively reduce the damage of the watermark. Also, an adaptive watermark embedding method can be considered such that the embedded watermark value is proportional to an average value of the pixel. In order to overcome non-robustness that is a common disadvantage of the conventional methods based on the conventional patchwork method or the conventional modified patchwork method, not a single pixel but sample-expanded pixel is chosen, and there is proposed a spatial domain blind watermarking method using a watermark value that is proportional to an average value of pixel every tile.

摘要： Provided are a microprocessor suitable for constructing a multi-processor system and a method for controlling the reset and processor ID of the microprocessor. The microprocessor includes decoder receiving a reset ID having a predetermined binary value and a reset signal and decoding the reset ID, an ID generator receiving the decoding result of the decoder and generating at least one microprocessor ID and a reset ID of a microprocessor serially connected to the microprocessor, and a reset vector unit selecting a reset vector according to the decoding result of the decoder. The multi-processor system is constructed such that independent microprocessors of the system respectively generate their own reset vectors and processor IDs when a reset signal is input to the multi-processor system to initialize it. Thus, all the microprocessors of the system can be simultaneously started up when the reset signal is disabled. Accordingly, a resetting process in the multi-processor system is simplified, a period of time required for starting up the microprocessor is reduced, and the multi-processor system is easily designed.

摘要： A cache coherency maintenance system and method of a user file manager in an object-based storage system are provided. According to the cache coherence maintenance system and method, by maintaining the coherency of a writeback cache based on time using a timer, metadata and data information are efficiently managed. Accordingly, even when accesses by users increase, the cost of maintaining the coherency of the cache is distributed to respective user file managers. In this way the performance of the entire object-based storage system is enhanced and the consistency and efficiency of information increase.

摘要： An efficient snapshot technique based on a mapping for a large logical volume shared in multiple hosts. According to the present invention, problems of time delays in a conventional snapshot technique is solved by employing a FAB and an SSB, which are bits representing whether a COW operation is carried out to a mapping entry. In other words, the present invention solves the problems of delaying a write operation of corresponding volume, which is simultaneously executed when a snapshot is created, until the snapshot creation is completed.

摘要： A hardware apparatus for receiving a packet for a TCP offload engine (TOE), and receiving system and method using the same are provided. Specifically, information required to protocol processing by a processor is stored in the internal queue included in the packet receiving hardware. Data to be stored in a host memory is transmitted to the host memory after the data is stored in an external memory and protocol processing is performed by the processor. With these techniques, it is possible that a processor can operate asynchronously with a receiving time of a practical packet and it is possible to reduce an overhead that processor deals with unnecessary information.
