  1. Spezielle Anwendungen des VLSI – EntwurfsApplied VLSI design ASIC design for an RGB  YCbCr-transformation Resultsof Phase 4 Florian Ludwig

  2. Parallel prefixadders • Sklanskyadder • Regular andsmallarea • Large fan-out • Kogge-Stone adder • Minimum logicdepth • Minimum fan-out • Large but fast adder • Brent-Kung adder • Maximum logicdepth • Minimum area • Small but slowadder

  3. Comparison I

  4. ComparisonII • 1 - compile_ultra-area_high_effort_script • 2 - compile_ultra -timing_high_effort_script • 3 - compile-exact_map -ungroup_all -area_effort high -map_effort high -power_effort high

  5. Layout for ST65 technology • Utilisation • Optimisation in Encounter • Increasefrequency • Also increasesleakage • Noimprovement in metric

  6. Results

  7. Thank you for your attention!
