ABSTRACT:
The invention relates, in general, to circuits and techniques for generating numbers and, in particular, to digital semiconductor circuit for generating large numbers. For generating such large numbers a large number generator circuit is used, comprising first means having an output for providing a first operand to a first input of a processing unit, second means having an output for providing a second operand to a second input of said processing unit, an output of said processing unit being operatively connected to an input of an arithmetic unit for generating a large number, wherein said second operand is generated by said second means using a parameter having far fewer number of p bits than the number of bits of the first operand.The use of parameters of a significant shorter length of bits has been proven to be less time consuming and much faster in generating large numbers, as special operands of a significant long length of bits are no longer to be read and written from and to the memory unit.
