5. M2: Team Paradigm Layout Size Proposal :Using a reference of layout of basic gates -And referencing devices from 322 to get accurate sizing :Furthermore we did this on basic gates, then scale accordingly for larger instances -for example: a 20 16bit registers will just be the stacked on top of each other -->single register mainly length multiplied by 16 then by 20 :Our design has total of approx 29k -add space for wiring... cannot give an accurate measurement for :Total area estimation of square area = 300,000um 2

7. M2: Team Paradigm Larger Components Breakdown :Mirror Adder: 28 Transistors including inverters -Faster than 5 gate adder -for 16bit multiply single cell by 16 -approx (12x16) x 7 = 198 x 7 -Subtractor only slightly larger -due to inverters Adder/Sub

8. M2: Team Paradigm Larger Components :Mux -2:1mux - 4.45 x 9.315 -4:1mux – 8.91 x 18.6 -16bit = 9x(16 x 19) :Control Logic -Mixture of basic gates -estimate 1000 trans 16bit 4x1 mux

9. M2: Team Paradigm Larger Components :Shift Register -16 x 18.6 single bit cell -20 bit = (18.6 x 20) x 16 :Basic Register -9.27 x 5.02 single bit cell -16 bit registers - 150 x 5 shift reg reg

10. M2: Team Paradigm Larger Components :nand ROM (due to size) -there are two -1 rom = banks -1 bank = 16 words -1 word = 16 bits :each bank: 10u x 12u -total size = 120u --> 1 rom = 496 -->12 x 48
