    摘要: A management module registers a request to convert code from a first code set to a second code set, identifies a code set converter (CSC), determines whether a most recently used CSC is the identified CSC and, in response to determining that the most recently used CSC is not the identified CSC, locates a user-preferred CSC pool comprising a subset of locally stored CSCs each corresponding to a preference index. The management module, in response to determining that the identified CSC is located within the user-preferred CSC pool, searches the user-preferred CSC pool for the identified CSC, loads the identified CSC, initiates the identified CSC that converts the code from the first code set to the second code set, modifies usage data for the identified CSC, and orders the user-preferred CSC pool based on a preference index for each CSC stored in the CSC pool.

    摘要: There is realized a data conversion device that performs generation of a hash value with improved analysis resistance and a high degree of safety. There are provided a stirring processing section performing a data stirring process on input data; and a compression processing section performing a data compression process on input data including data segments which are divisions of message data, the message data being a target of a data conversion. Part of multi-stage compression subsections is configured to perform a data compression process based on both of output of the stirring processing section and the data segments in the message data. There is provided such a configuration that the stirring process is executed at least on fixed timing of a compression processing round of plural rounds and thus, there is realized a data conversion device that performs generation of a hash value with improved analysis resistance and a high degree of safety.

    摘要: A data-processing device includes a plurality of data generation units, a plurality of bit change number calculation units, a bit change number comparison unit, a first data selection unit, and a bit-coupling unit. The data generation unit arranges input data to generate first conversion data based on each prescribed arranging method. The bit change number calculation unit compares values of respective bits in the first conversion data output at the n-th time and the (n+1)-th time by the corresponding data generation unit, and calculates a bit number based on the comparison result as a bit change number. The bit change number comparison unit compares values of the respective bit change numbers, selects the data generation unit, and outputs selection information. The first data selection unit outputs any one first conversion data selected based on the selection information as selection data. Then, the bit-coupling unit couples the selection information.

    摘要: A data processing apparatus includes processing circuitry for performing a convert-to-integer operation for converting a floating-point value to a rounded two's complement integer value. The convert-to-integer operation uses round-to-nearest, ties away from zero, rounding (RNA rounding). The operation is performed by generating an intermediate value based on the floating-point value, adding a rounding value to the intermediate value to generate a sum value, and outputting the integer-valued bits of the sum value as the rounded two's complement integer value. If the floating-point value is negative, then the intermediate value is generated by inverting the bits without adding a bit value of 1 to a least significant bit of the inverted value.
