NAND2TETRIS HARDWARE SIMULATOR (HARDWARE DESCRIPTION LANGUAGE (HDL)) implement simplified Z80 Arithmetic and Logic Unit using the skeleton program below , also using the predifined gates which are in the images attached CHIP ALUcore { IN a[4], b[4], carryIn, sums, ands, xors, ors; OUT out[4], carryOut; PARTS: }

Assignment Content Given an array of integers Arr, calculate the pivot index of this array. The pivot index is the index where the sum of all the numbers strictly to the left of the index is equal to the sum of all the numbers strictly to the index's right. If the index is on the left edge of the array, then the left sum is 0 because there are no elements to the left. This also applies to the right edge of the array. Return the leftmost pivot index. If no such index exists, return -1.

Logic circuits, plllleeease solve parts C and D, thanks siirrr

The next_pattern module provides the next state function for a Finite State Machine (FSM) that generates the following sequence of patterns: 0, 2, 1, 3 The first pattern follows the last pattern. Any patterns not in the sequence should be considered as do not cares. The next function will not be tested for these patterns. Editor Test Bench module next_pattern(output logic [1:0] next, input logic [1:0] cur); endmodule

2. Design a circuit to implement the following pair of Boolean equations: F = A(CE' + DE) + A'D G = B(CE' + DE) + B'C To simplify drawing the schematic, the circuit is to use a hierarchy based on the factoring shown in the equation. Three instances (copies) of a single hierarchical circuit component made up of two AND gates, and OR gate, and an inverter are to be used. Draw the logic diagram for the hierarchical component and for the overall circuit diagram using a symbol for the hierarchical component.

2) Simplify the following expressionF (A,B,C,D) = (A’+ B’+D’)(A+B’+C’)(A’+B+D’)(B+C’+D’) in2.a) SOP form and implement it with only NAND gates. 2.b) POS form and implement it with only NOR gates.

3- What is the minimum number of gates required to implement the Boolean function (X+YZ) if we have to use only 2-input NOR gates? a) 2 b) 3 c) 4 d) 6

A c++ program that implements full adder for n bits.(Eg if n=4,the program should add two 4 bit numbers and show the output as sum as well as carry)

NAND2TETRIS HARDWARE SIMULATOR HiLoMux - This has one 8-bit input bus, in, and one 4-bit output bus, out. Alsopresent is a sel input, which is used to select what appears on out. Ifsel is false, then out should contain the lower 4-bits of in (i.e. in[0],in[1], in[2], in[3]). If sel is true, then out should contain theupper 4-bits of in (i.e. in[4] mapped to out[0], in[5], mapped toout[1], etc.). In other words, the HiLoMux can be used to select anibble from a byte please use the skeleton program below CHIP HiLoMux{ IN in[8], sel; OUT out[4]; PARTS: }

Figure Q7 describes a Linear Feedback Shift Register (LFSR). Draw the equivalent schematic diagram of the system based on an off-the-shelf shift register, clearly showing the number of exclusive-OR gates needed to construct it. LIBRARY ieee; USE ieee.std logic_1164.all; entity lfsr is CLK, RESET: in STD LOGIC; Q: out STD LOGIC_VECTOR (5 downto 0) ); port ( end lfsr; architecture behavior of lfsr is begin process (CLK,RESET) begin if RESET='1' then Q <= "000001"; else Q <= ( Q(3) xor Q(2) xor Q(0) ) & Q(5 downto 1); end if; end process; end behavior;

How many registers does this design implement? module BitReverser ( input logic clk, input logic Rst, input logic [7:0] DataIn, output logic [7:0] DataOut ); assign Dataout [7] = DataIn[0]; assign DataOut [6] = DataIn[1]; assign Dataout [5] = DataIn[2]; assign DataOut [4] = DataIn[3]; assign DataOut [3] = DataIn [4]; assign Dataout [2] = DataIn[5]; assign DataOut [1] = DataIn[6]; assign Dataout [e] = DataIn[7]; endmodule Pick one of the choices 00 01 04 08

1. Write program in c++ language to implement-logic-gates (AND-OR), Without using (if condition). Assume that(a=input1,b=input2,y%3Doutput for AND gate, z=output for OR gate). D Y B A B 2. Determine the value of variables after executing each of the following C++ Statement. (all variables are integer). zl=x++*y; z2=2*++x*y; y%=x; x+=4+--y/x–3;
