Design proposal of reconfigurable shift unit based on multilevel interconnect barrel shifter is presented, which can support 8~32 bit wide and any variable length between 1 bit and 31 bit. Through adding expander circuit, the width of this unit can broaden to 8~128bit. The design has been realized using Altera’s FPGA and synthetized and optimized on Synopsys’s Design Compiler. The result proves that the maximum frequency can achieve 400MHz on 0.13µm CMOS technology.
