Design and Analysis of Radix-8/4/2 64b/32b Integer Divider Using COMPASS Cell Library

[摘要] A high speed 64b/32b integer divider employing digit-recurrence division method andthe on-the-fly conversion algorithm, wherein a fast normalizer is included, which is usedas the pre-processor of the proposed integer divider. For the sake of enhancingthroughput rate, the proposed divider uses a mixed radix-8/4/2 division instead of thetraditional radix-2 division. On-the-fly remainder adjustment is also realized in theconverter module of the divider. The entire design is written in Verilog HDL (hardwaredescription language) employing COMPASS 0.6 μm 1P3M cell library (V3.0), and thensynthesized by SYNOPSYS. The simulation results indicate that our design is a betteroption than the existing long divider designs.
