<P>PROBLEM TO BE SOLVED: To provide a product-sum computing element for automatically generating the address of a register in which a plurality of calculation data are stored, obtaining the output of data in the midst of calculation processes and the notification of an overflow, improving the processing efficiency of the product-sum computing element, and simplifying a recursive filter. <P>SOLUTION: This product-sum computing element is provided with a coefficient register 100, a data register 110, a multiplier 130, an adder 140 and a data bus 120 for performing data transfer to/from an external device. This product-sum computing element is further provided with a data collectively automatically storing means 180 for automatically generating the data storage address only by inputting an address showing the data register 110 only once at the beginning from the outside without individually designating all the addresses of the data register 110 from the outside, and storing a series of data. Also, recursive product-sum calculations are performed by automatically storing intermediate result data in the midst of the product-sum calculation processes into the data register 110. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
