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?
