Title: Divider
Inventor: TSUJIMICHI SHINGO
IPC: G06F7/535
Filed: 1986-09-12
Abstract: PURPOSE:To shorten processing time by connecting a zero detecting circuit and a flag register for indicating whether either one of two recent zero detecting results is zero or not to an output part of an adder/subtractor, and at the time of indicating flag zero, converting the code of a dividend to positive to execute the judgement of a correcting condition. CONSTITUTION:The zero detecting circuit 10 always executes zero detection of partial residual, the newest detected result and the preceding result are stored respectively in registers 11, 12 and the contents of these registers 11, 12 are updated every calculation of new partial residual. When a control circuit 7 checks the values of the registers 11, 12, and detects either one of them is zero, the code XS of a divided stored in the register 6 is turned to positive. Then correction similar to the ordinary one is executed by the codes XS, YS, AS of the dividend, a divisor and the partial residual stored in respective registers 6, 8, 9 to calculate the residual R and a quotient Q. Since the method completely coincides with the conventional method by finally inverting the code of the partial residual, the conventional correcting method is applied to all cases by converting the code of the dividend always to positive when the residual is '0' to calculate the quotient and the residual correctly.
