Research of Design Technology of Reconfigurable Shift Unit Based on Multilevel Interconnection

摘要

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 0.13 μm CMOS technology.
