Abstract: PURPOSE:To speed up a processing, by arranging a numeric function arithmetic processor in parallel with an integer arithmetic processor and a floating point arithmetic processor, and operating it independently in parallel with them. CONSTITUTION:Each token outputted from a data memory 14 is inputted to either an integer arithmetic processor queue 24, a floating point arithmetic processor queue 25, or a numeric function arithmetic processor queue 26 corresponding to its processing code, and is inputted to succeeding integer arithmetic processor 20, floating point arithmetic processor 21, and numeric function arithmetic processor 22. Even while the numeric function arithmetic processor 22 occupies hardware by one of data by performing a repetitive processing with a variable time, the integer arithmetic processor 20 and the floating point arithmetic processor 21 receive the supply of input tokens from a buffer queue 15 corresponding to them, and are operated in parallel. In such a way, a fast processing can be realized.

Abstract: PURPOSE:To reduce a token flow rate and to realize a fast operation, by generating the access address of a function table by performing an arithmetic operation by using a systemizer different in each token. CONSTITUTION:When the sum of vector data with length of N is obtained, a pair of tokens with the length of N that is attached on the vector data are used. Those tokens are provided with the systemizers other than link table addresses and data values, and after the same function table base address is obtained by referring to a link table 12, the access address of a function address table 13 can be obtained by performing the arithmetic operation of the function table base address and the systemizer at a function table address generation part 20. In such a way, it is possible to perform the preceding and succeeding processings continuously with an intermediate processing only by sending N tokens for one time to an arithmetic part, and to reduce a load on a program and to realize the fast processing.

Abstract: PURPOSE:To process data having accuracy of two-word quantity without changing the bit width of the data value, by providing a double-accuracy processing and controlling unit which processes double-accuracy data composed of continuous two words together with a processor unit. CONSTITUTION:In the case of the operation of data which requires the accuracy of two-word length, the data are given to this device after dividing them into continuous two words and a bit which indicates that the data are to be processed in the unit of the two words with double accuracy is given to the first one of each two words. Each data circulate the ring bus of the device and are successively calculated by a processor unit 6, but, when it is indicated that the data and continuous data are of double accuracy by the bit of the data, calculated results of the first word which are necessary for calculating the next coming second word are given through a double-accuracy processing and controlling unit 7 which holds the internal state of the processor unit 6 and double-accuracy calculation is executed. Therefore, processes by double- accuracy data can be executed while the bit width and function of conventional data value are maintained.

Abstract: PROBLEM TO BE SOLVED: To provide an information processing apparatus in which a user himself/herself is capable of decrypting contents of file only by inputting biometrics data without saving a cryptographic key when encrypting the contents.
SOLUTION: An intrinsic value peculiar for an individual is calculated from the inputted biometrics data and based upon the intrinsic value, a key to be used for encrypting the file is calculated. In decryption, only when one and the same biometrics is inputted, the same key is calculated, thereby decrypting the file.

Abstract: PROBLEM TO BE SOLVED: To provide a low cost and low overhead fingerprint authenticating method for determining the suitability of an input image to a fingerprint sensor from the widely ranged points of view only by software, and authenticating the fingerprint by combining it with a characteristic collation result.
SOLUTION: The spacial frequency analysis of an input image is used for determining the suitability of an input image to a fingerprint sensor. At first, the Fourier conversion image(middle stage) of an input image(upper stage) is calculated. It is detected that a spot (A) corresponding to the cyclic structure of a ridge and a spot (B) corresponding to a structure whose cycle is smaller than that of the ridge due to sweat duct prongs clearly appear in the Fourier conversion image corresponding to a fingerprint real spacial image obtained under proper conditions. The mean strength (a) or distribution (b) of a frequency band including the frequencies of the spots A and B are used in featured values to be used for determining the suitability of the input image so that it is possible to determine whether or not the input image is suitable.
