ABSTRACT:
Disclosure is made of a method for dividing two numbers, whereby the numbers are converted to the binary code, and there is formed an address code of three digits of the dividend (the or remainder) by determining the position of the highest-order significant digit in the three high-order digits of the divisor. The address thus formed serves to produce three digits of the remainder, i.e. a digit corresponding to the highest-order significant digit of the divisor code and two adjacent higher-order digits. The three digits of the remainder are analyzed and, depending upon the result of the analysis, the code of either the single, or doubled, or trebled divisor is subtracted from the remainder code, whereby the next two quotient code digits are produced.
Disclosure is further made of a device for effecting the proposed method for dividing two numbers, which comprises an arithmetic unit connected to dividend (or remainder) registers, buffer registers, divisor registers and quotient registers. The device further includes a converter of the code of the three high-order divisor digits to the address code of the three remainder digits, whose information input is connected to an output of the divisor register. The output of said converter is connected to one of the information inputs of a three remainder digits selection commutator. Another information input of the commutator is connected to an output of the dividend (or remainder) register. The output of said commutator is connected to the input of a three-digit register which is connected to one of the inputs of a microprogram control unit of said division device. The output of the control unit connected to the control inputs of all the elements of said device.
