| 总结: | This study investigates the relative performances of Array,
Wallace, Dadda and Reduced Area multipliers for several
synthesis optimization modes. All multiplier designs were
modeled in Verilog HDL and synthesized based on the
TSMC 0.35-micron ASIC Design Kit standard cell library.
Performance data was extracted after logic synthesis in
LeonardoSpectrum for Area, Speed and Auto optimization
modes. Findings indicate that the Dadda multiplier may not
always have a speed advantage over Wallace’s design, but
depends greatly on the optimization effects in gate-level
synthesized design. Results for comparison of 32x32-bit
variants indicate that the Wallace scheme is well suited for
high-speed applications, independent of area constraints,
while the Dadda and Reduced Area designs deliver best
speed when synthesized to minimize area or logic usage. |
