Presentation Transcript

  1. Spezielle Anwendungen des VLSI – Entwurfs Applied VLSI design Course and contest Results of Phase 3 Andy Schellin

  2. Problems with last design • 40-Bit ripple carry adder • One universal csa-array-multiplier for all coefficients • 24-Bit ripple carry adder

  3. Further design improvements • Further optimization of coefficients • Implementation of specific shift-multipliers for every coefficient • Reduction of the bit width down to 9

  4. Library comparison • Preset Values • Supply Voltage: 1.0V • Frequency: 1600MHz LPSVT LPHVT

  5. Iterative search for best metric • Preset Values • Supply Voltage: 1.0V • Compile_ultra

  6. Results

  7. Thank you for your attention
