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. The result is then recycled, if needed, to the input list until an eventual result is obtained, each cycle of a multi-cycle operation being influenced only by the output of the result of the next preceding cycle presented on the output bus. The output list then becomes, through this recycling operation, the input list to be further processed.
