Abstract: A method of developing a fast algorithm for a double precision shift operation is disclosed. The proposed shift operation only requires two instruction cycles, by which the first instruction calls for shifting out of a predetermined number of bits of a first operand at a first memory location into a shift register; and then the second instruction calls for shifting of the same number of bits of a second operand at a second memory location, and then performing a logical OR operation with the shifted operand and the overflow data in the shift register, and finally storing the operation result to the second memory location. As such, the proposed algorithm is able to reduce the number of instructions needed as compared with conventional methods, thus the overall efficiency of the data operation can be greatly improved.
