Abstract

Abstract A binary number stored in an N stage register is shifted a bit at a time, most significant bit first, into a serial divider. The divider is adjustable in the sense that it may be set to divide by any number R, where R is the radix of the number system into which the binary number is to be converted. The divider produces a quotient bit in response to each bit it receives and produces a multiple bit, binary-coded character to the new base after each N shift pulses. The quotient bits are shifted back into the least significant bit position of the register as they are produced.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 210 words
A circuit for changing a number to one base to a number to any one of M other bases comprising, in combination: a divider which can be adjusted to divide by any integer chosen from a group of M such integers, where M is an integer greater than 1; control means for setting said divider to perform a division by any one of the integers in said group; means for applying a number to a base other than R to said divider and obtaining therefrom a quotient Q and a remainder T, where said control means has set said divider to divide by the integer R in said group; means for applying each quotient thereby obtained back to the divider to obtain, in each case, a new quotient and new remainder until the final remainder obtained is of a value less than that of the integer R, whereby each remainder T obtained by the divider is a character of different significance; and said control means including means for maintaining R at one value during the first division in which a remainder is obtained, and for thereafter setting the value of R to any desired value from 2 to M during any other division in which a new remainder is obtained.
Claim 2
Dependent Claim 210 words
A circuit for changing a number to one base to a number to any one of M other bases comprising, in combination: a divider which can be adjusted to divide by any integer chosen from a group of M such integers, where M is an integer greater than 1; control means for setting said divider to perform a division by any one of the integers in said group; means for applying a number to a base other than R to said divider and obtaining therefrom a quotient Q and a remainder T, where said control means has set said divider to divide by the integer R in said group; means for applying each quotient thereby obtained back to the divider to obtain, in each case, a new quotient and new remainder until the final remainder obtained is of a value less than that of the integer R, whereby each remainder T obtained by the divider is a character of different significance; and said control means including means for maintaining R at one value during the first division in which a remainder is obtained, and for thereafter setting the value of R to any desired value from 2 to M during any other division in which a new remainder is obtained.
