摘要

PROBLEM TO BE SOLVED: To provide a high speed, small size and inexpensive convolutional integration arithmetic unit to be used as an interpolation device capable of easily changing a degree of parallelism and dimension. SOLUTION: This folding integration arithmetic unit is constituted by providing a barrel shifter to successively read memory data matrixes by every specified number m, to shift and output them, providing the specified number m of product sum calculating part matrixes formed by vertically connecting plural product sum calculating parts formed by connecting two inputs a and b and providing an output f to output the product between weight W and the input b and the sum of the input a and an output g to use the input b as output, a processing is performed by successively outputting the input b of each product sum calculating part in the first line from memory data in the input a of the product sum calculating part on the lower line and successively outputting the input b in the input b in the product sum calculating part on the left adjacent part and the lower line.
