3 This question is about Digital Logic(a) Briefly explain how several Full-Adder circuits can be chained together to add upmulti-bit values.(b) A computer is being designed using a microprocessor with a 16-bit address bus(A0 -A15). The 64K address space is to be split and allocated to RAM, ROM and I/0hardware as follows:Address Range (hex) ContainsSelect SignalOx0000-OX0OFFROMROMCSOx1000-0X1FFFRAM Bank 1RAMICSI/ORAM Bank 2Ox2010-Ox2012IOCSОx8000-0xFFFRAM2CSThe rest of the address space is unused.Note: As with many computer systems, it its only necessary to decode the address tosufficiently identify each of the four stages above. It is acceptable for some parts to bedecodeable by more than one address provided these extra addresses do not over-lap any of the other specified address ranges.Using a combination of AND, OR and NOT gates and the signals for the address bus(A0- A15) that contain the address in binary form:() Derive the equation for a logic signal, ROMCS, which is true if the address bus con-tains an address in the range for the ROM.(i) Derive the equation for a logic signal, RAMICS, which is true if the address buscontains an address in the range for RAM Bank 1.(iii) Derive the equation for a logic signal, 10cs, whtains an address in the range for the I/0.is true if the address bus con-(iv) Derive the equation for a logic signal, RAM2CS, which is true if the address buscontains an address in the range for RAM Bank 2.

Sir, please solve this problems asap. Thank you!
You are asked to design a circuit to detect if an overflow occurs when subtracting two integers represented in two's complement: Z= X - Y. Let Sz, Sx, and Sy be the sign bit for Z, X, and Y respectively, and they are fed as input to the circuit. Let O be the output bit of the circuit, whose value is 1 if an overflow happens, and 0 if otherwise. a) Build the truth table for O as a Boolean function of Sx, Sy, and Sz. b) Write the canonical expression (sum-of-product) for the Boolean function defined in the part a. c) Implement the Boolean expression defined in part b with a circuit by using AND, OR, and NOT gates. Draw the wiring diagram.
