Patent JP-H0279120-A (JP)
Title: Adder/subtracter
Inventor: NAKANO HIROSHI
IPC: G06F7/508
Filed: 1988-09-16
Abstract: PURPOSE:To make the arithmetic operation stating time of an adder/subtracter earlier and, at the same time, to improve the actual subtraction speed of the adder-subtractor by dividing carry propagation adders into two stages of a preceding stage and succeeding stage and respectively setting the bit widths of the preceding and succeeding stages to N and 2N. CONSTITUTION:After magnitudes of exponent sections set in registers 12 and 13 are compared with each other by means of an adder-subtractor 23, the exponent character of the exponent having the larger magnitude is selected and set in a register 36 and the difference in the exponent characters is supplied to a shifter 32. Then selectors 33 and 34 select numbers to be operated and operands of high-and low-order N bits. At the time of the selection, addition-subtraction of a 2N-bit width is carried out by a full adder 60 and look-ahead carry circuit 61 by inputting half-addition results, carry occurring conditions, and carry propagating conditions to the high-order N bits held by registers 50-52 and half-addition results, carry occurring conditions, and carry propagating conditions to low-order N bits outputted from a carry occurring conditions/carry propagating conditions production circuit 41. Moreover, calculated results are outputted after post-normalization is performed on the results. Therefore, the arithmetic operation starting time can be made earlier and the actual subtraction speed can be improved.
