Abstract
A barrel shifter is provided with a plurality of shifters arranged in series for combining pieces of data A, B respectively represented by a sequence of 32-bit, 16-bit, or 8-bit binary digits into a piece of combined data C and shifting the combined data C by some bits. The shifters consists of a 16-bit shifter, 8-bit shifter, 4-bit shifter, 2-bit shifter, and two 1-bit shifters. The 32-bit data A, B are shifted in the 16-bit shifter. The 16-bit data B is shifted in the 16-bit shifter to connect with the 16-bit data A. The 8-bit data B is shifted in the 16-bit shifter to approach the 8-bit data B. The combined data C formed by connecting the 32-bit data A, B or the 16-bit data A, B in the 16-bit shifter is shifted in the following shifters. The 8-bit data B in the 16-bit shifter is shifted in the 8-bit shifter to connect with the 8-bit data A so that the combined data C is formed. The combined data C formed by connecting the 8-bit data A, B in the 8-bit shifter is shifted in the following shifters.
