The mask _____ can be used to isolate bit #2 of an 8-bit register.     00 H     FF H     02 H     04 H

The state of a 12-bit register is 100010010111. What is its content if it represents Three decimal digits in the 84-2-1 code?

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 2: Build a 8 bit controlled 2's Complement Inverter as a subcircuit named 8BitInverter

Use the optimized division hardware to perform 11111 ÷ 01110. In the input box below, show the bit value of the divisor and the remainder/quotient register after Step 2 in the exact given order and separate them with comma.

Pair B contains 1122H and pair D contains 3344H. WAP to exchange the contents of B and D pair using XCHG instruction.

4 bit 2’s Complement Multiplier INPUT A: 4 bit 2’s Complement numberINPUT B: 4 bit 2’s Complement numberOUTPUT: 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 as a subcircuit named 4BitInverter PART 2: Build a 8 bit controlled 2’s Complement Inverter as a subcircuit named 8BitInverter PART 3: Build a 4 Bit UNSIGNED Multiplier as a subcircuit named UnsignedMultiplier     PART 4: Using the 3 subcircuits you built in Parts 1-3, built a 4 bit 2’s Complement multiplier that uses the inversion method discussed in class.  Name this circuit:  SignedMultiplier HINTS: INVERSION METHOD: 1) If input A is negative, invert it. If input A is…

ADC to UART Program the PIC24HJ microcontroller so that the UART displays: • integer ADC 12 bit value acquired from AN5, • the approximate voltage that is applied to AN5,

4 bit 2’s Complement Multiplier INPUT A: 4 bit 2’s Complement numberINPUT B: 4 bit 2’s Complement numberOUTPUT: the product of A x B represented as a 8 bit 2’s Complement number   Do this:Build a 4 Bit UNSIGNED Multiplier as a subcircuit named UnsignedMultiplier use AND gate ,full and half adders for the circuit
