摘要： In a signal processor for processing zeroth through (N-1)-th input signal elements into zeroth through (N-1)-th output signal elements, the input elements are initially stored, as memorized data, in respective memory addresses of a memory arrangement (11, 12) by a memory accessing arrangement which comprises a first address calculating arrangement (311, 321) for calculating a first address for the memory addresses. A distance indicating arrangement (312, 322) is for indicating an address distance from the first address among the memory addresses. By using the first address and the address distance a second address is calculated by a second address calculating arrangement (313, 323). A pair of stored data are read from the first and the second addresses as a pair of read data. A calculation performing circuit (20) is for performing a predetermined calculation on the pair of read data by using a coefficient read from a read-only memory (14) to produce a pair of calculated data which are stored in the first and the second addresses as the stored data. The calculation performing circuit performs the predetermined calculation a plurality of times to produce the output elements.

摘要： A double precision multiplyer for performing the multiplication of two double precision data using a 2's complement single precision multiplier. The 2n-1 bit double precision data is divided into one single precision data formed by taking the upper n bits of the double precision data and another single precision data formed by adding a "0" bit before the most significant bit of the remaining n-1 bits of the double precision data. Apparatus for performing the double precision multiplication thereby eliminates the necessity of discriminating the sign bit and enhances the speed of the double precision multiplication.

摘要： In a processing circuit for successively accumulating a first predetermined number of products, each product is shifted in a barrel shifter (20) downwards by a second predetermined number of bits determined in relation to the first predetermined number and is successively added to a previous result of accumulation in an arithmetic/logic unit (ALU) (21) the first predetermined number of times to produce a final result of accumulation. The first result is shifted in a shifter (27) upwards by a third predetermined number of bits determined in relation to the second predetermined number. An overflow detector (26) monitors each result of accumulation to detect occurrence of an overflow in the ALU and the shifter to substitute either a positive or a negative maximum number for each result by an overflow corrector (25) on occurrence of the overflow. The substituted maximum number or the shifted final result is produced as an output signal.

摘要： Overflow monitoring circuitry for an arithmetic unit offsets consecutive positive and negative overflows against one another to eliminate unnecessary overflow compensation during an arithmetic operation. In a first embodiment, an up/down counter is used to count positive overflows in one direction and negative overflows in another, with the value of the counter at the end of the arithmetic operation indicating the net overflow, if any has occurred, and the most significant bit of the counter representing the direction of any net overflow. In a second embodiment, logic circuitry offsets alternate positive and negative overflows against one another but will provide an overflow signal if either an odd number of overflows occurs or if two consecutive overflows in one direction occur during the arithmetic operation.

摘要： An authentication apparatus comprises a first acquiring part for acquiring three-dimensional shape information of a face of a target person to be authenticated, a compressing part for compressing said three-dimensional shape information by using a predetermined mapping relation, thereby generating three-dimensional shape feature information, and an authenticating part for performing an operation of authenticating said target person by using said three-dimensional shape feature information. When a vector space expressing said three-dimensional shape information is virtually separated into a first subspace in which the influence of a change in facial expression is relatively small and which is suitable for discrimination among persons and a second subspace in which the influence of a change in facial expression is relatively large and which is not suitable for discrimination among persons, said predetermined mapping relation is decided so as to transform an arbitrary vector in said vector space into a vector in said first subspace.

摘要： An autonomous vehicle capable of traveling and stopping parallel to a wall includes right and left driving wheels receiving driving force to be driven independently, a dependent wheel for supporting the autonomous vehicle together with the driving wheels for a straightforward movement and a U-turn, a motor for driving the right and left driving wheels, a coupling mechanism for transmitting the rotation of the motor to the driving wheels, an encoder for detecting the rotation amount and velocity of the motor, a gyro sensor for detecting the direction of the autonomous vehicle, a distance measurement sensor for measuring the distance to a right or left object of interest, and a controller for controlling the autonomous vehicle through the motor and the driving wheels. The controller receives the output of the encoder, calculates a control value for the driving wheels based on the rotation amount and rotation velocity of the motor, and determines that the autonomous vehicle travels parallel to the wall if the ratios of a time period to turn the autonomous vehicle rightward and a time period to turn the vehicle leftward in a prescribed time period are equal based on the control value.
