Provided are an initial synchronization acquiring device and method in a parallel processed DS-CDMA UWB system and a DS-CDMA UWB system’s receiver using the same. A stream transmitting unit receives the table and the frequency of transmission, converts the table to stream information, and transmits a stream at a frequency determined based on the transmission frequency. The casting mold includes a header plate, a casting ring, and a feed ring. A product manager generates a first artifact version string for the first artifact based on the first source code version string of the first source code version used to build the first artifact. If the new mapping produces a sufficient improvement in the distribution of interrupts among the processors, based on the same criteria used to detect the imbalance, the new mapping is used by the central hub for subsequent distribution of interrupts to the processors. Its perimeter has at least two longitudinal portions, and each of them has a concave portion that passes into convex portions at both sides.
