Abstract: A method and a device to perform arithmetic, arithmetical, logical and related operations on numerical value elements is characterized by providing an input list including the numerical value elements to be processes, and instruction information on a predetermined number of inputs/output buses. The operation on the numerical value elements on the input list is directly controlled and performed using the instruction information. Various computing circuits adapted to perform a specific operation on the numerical value representations are connected on the input buses, thereby providing the results of their computations in parallel. The calculation in the arithmetic logical unit is performed by rewriting the elements in the input list. The result is presented as an output list.
