Data processing apparatus for performing cumulative processing on time series data

摘要

A vector operation data path (3) in a vector calculator is composed of a cumulative data selection unit (5) and a cumulative calculator (6). The cumulative data selection unit (5) outputs cumulative data Z(1) to Z(n) which are time series data on the basis of operation data A and operation data Y, sequentially to the cumulative calculator (6). A selector (66) in the cumulative calculator (6) outputs selected data S(i) by selecting one of differential data {Z(i)-Z(i+1)}, differential data {Z(i)-Z(i+2)} and cumulative data Z(i). The selected data S(i) is applied to an absolute value circuit (67) and a square circuit (68), and the obtained square data SQ(i) is given to an accumulator (69), and the accumulator (69) determines the cumulative value.
