METHOD FOR ARITHMETICALLY RIGHT-SHIFTING NEGATIVE BINARY NUMBER AND SYSTEM FOR RIGHT-SHIFTING NEGATIVE BINARY NUMBER

摘要

PROBLEM TO BE SOLVED: To provide a method and a system realized by a computer for arithmetically right-shifting m-bit negative number by (n).;SOLUTION: A right-shifter executes logical right-shift calculation for the number to be shifted. A left-shifter left-shifts an m-bit mask of one by one's component. OR calculation is executed on both the shift calculation results for providing a desired arithmetic right-shift result.;COPYRIGHT: (C)2002,JPO
