Abstract: A method is shown for computation of rational functions of many arguments given in a sequential code whereby the arguments are input and the results are output simultaneously. Regardless of the number of arguments the senior of digits of the result are formed in on steps and at every step only one digit of the argument is input. The paper gives algorithms for arithmetic operations using a redundant positional reference system for presentation of the operands and the results. The same algorithms can be used for fast computation of rational functions of an arbitrary type. The methods are easily realized in LSI units.
