Abstract: A communication device includes a storage unit to store quotients and remainders associated with multiplication values obtained by multiplying a specified integer number, which is expressed in a form of (2?+?) where ? is a positive integer number and ? is a positive integer number other than integral multiples of 2, respectively, the quotients and the remainders being obtained by dividing the multiplication values by 2?, respectively, a first unit to divide a dividend by 2?and calculate a quotient and a remainder, a second unit to obtain a quotient, which corresponds to the remainder from the storage unit, and a third unit to determine that the data length of the packet data is normal, when a combination of the quotient and the remainder calculated by the first unit is in the storage unit.

Abstract: A dividing unit sets an actual packet length transferred from a packet receiving section to a variable U, and then sets 2? to a variable V. If a positive number determining section determines that a subtraction result of subtracting a remainder N0 from a quotient M0, both found by dividing U by V, is a positive number, the dividing unit overwrites the subtraction result to U. The dividing unit repeats such operations of dividing the subtraction result by V, until the positive number determining section determines that the subtraction result of subtracting the remainder from the quotient, both found by dividing U by V, is a non-positive number. When the subtraction result becomes a non-positive number and the quotient and the remainder match, a packet length determining section determines that received data has a normal size, and notifies it to a discard determining section.

Abstract: A judgment apparatus includes a storage configured to store first reference data representing data that a detector should output in a first area when a detection target passed the first area, and second reference data representing data that the detector should output in the first area when the detection target passed a second area being different from the first area; and a processor to perform processes of: obtaining data from the detector outputting, in a time-series manner, data according to a detection condition of the detection target passing the first area or the second area; judging a degree of similarity between data obtained by the obtaining and the first and second reference data stored in the storage; and judging whether or not the detection target passed the first area, based on the judgment result by the judging the degree of similarity.

Abstract: A processing apparatus has a master processing module and a plurality of slave processing modules. The master processing module has a master recording unit and a slave recording unit recording part of the data recorded in the master recording unit. The slave processing modules access the master processing module when it is necessary to access the data recorded in the master recording unit. When the data to be accessed from one slave processing module is recorded in the slave recording unit, the master processing module transmits the data to be accessed, from the slave recording unit to the one slave processing module. In the processing apparatus such as a base transceiver station communicating with transceivers such as mobile telephones, a reduction in the overall cost of the apparatus and an efficient internal communication are realized, and the overall processing time is reduced.

Abstract: A data transferring unit performs hit determination on a cache memory based on a management table and a request from a CPU board. If requested data is not available in the cache memory, the data transferring unit reads and sequentially transfers the requested data from a shared memory in packets of optimum packet length stored in a time table in such a way that the previous packet is transferred while the next packet is read. In addition, the data transferring unit measures a packet transfer time. A packet-length optimizing unit varies, based on the packet transfer time calculated by the data transferring unit and data stored in the time table, an optimum packet length so that the difference between the packet transfer time and a packet read time is minimized.
