Last week’s challenges…
• Completing and Testing Top level Schematic (98% done)
• Creating Layouts for Floating Point Multipliers and Adders with different shapes.– For Wallace Tree, decided to split it into two
trees, incorporating Booth encoding.
• Clock Skew and other Timing issues– Don’t have to worry about it
• Transistor count .. again.. – Ok..
This week’s challenges…
• Completing and Testing Top level Schematic – Power Saving options??
• Wallace Tree Layout– Is Booth encoding only for 2’s
complement numbers??
• Functional Blocks Layout– Follow the Floorplan
Questions?
