ABSTRACT:
In a data processing circuit for calculating a total sum of a succession of data in a pipeline fashion, an arithmetic unit (28) carries out an addition iteratively on the data to produce intermediate results of addition. Work registers (31, 32), equal in number to the number of the pipeline stages, successively temporarily stores the intermediate results. Specifying circuit (35) cyclically specifies the work registers as specified registers to store the intermediate results in the specified registers in the pipeline fashion. Selector (33) selects each of the work registers as a selected register to supply the arithmetic unit with the intermediate result stored in the selected register. When the arithmetic unit carries out the addition on all the data, contents of the work registers are added to each other by the use of the arithmetic unit to provide an ultimate result representative of the total sum.
