Abstract
A computer-implemented method and system for performing an arithmetic shift right by n of an m-bit negative number. A right shifter executes a logical shift right operation on the number to be shifted. A left shifter performs a left shift on an m-bit mask of ones, left shifting the mask by the one's complement of n. An OR operation is then performed on the results of the two shifting operations, producing the desired arithmetic shift right result.
