本次美国代写是一个logisim乘法器相关的project

4 bit 2’s Complement Multiplier

INPUT A: 4 bit 2’s Complement number
INPUT B: 4 bit 2’s Complement number
OUTPUT: the product of A x B represented as a 8 bit 2’s Complement number

You are only allowed to use the basic gates: NOT, AND, OR, XOR. You may however, use these basic gates to build your own custom circuits (i.e. Adder). You are NOT ALLOWED to use Logisim’s built in circuits. Each custom circuit is to be implemented as a sub-circuit as discussed in class.

PART 1: Build a 4 bit controlled 2’s Complement Inverter

PART 2: Build a 8 bit controlled 2’s Complement Inverter

PART 3: Build a 4 Bit UNSIGNED Multiplier

PART 4: Using the custom circuits you built in Parts 1-3, built a 4 bit 2’s Complement multiplier that uses the inversion method discussed in class.

HINTS: INVERSION METHOD:

1) If input A is negative, invert it. If input A is positive, leave it alone.
2) If input B is negative, invert it. If input B is positive, leave it alone.
3) Multiply A and B.
4) If both A and B originally had the same sign (both positive or both negative), do nothing.
5) If A and B originally had different signs (one was positive, the other negative), invert the product.
