Overview

In this assignment you are required to implement binary code comparator using Xilinx that it is compatible with the MXK Seven Segment Displays. You will draw your digital logic circuit using Xilinx and then simulate it to verify the functionality of your design.

Software Requirements

? Xilinx ISE 10.1 or higher

Binary Code Comparator

The binary code comparator is to be implemented and made compatible with the seven 7-segment displays of the board. Represent the first five digits of your student number into binary. If a given decimal digit is odd, then the binary equivalent will be 1, otherwise it will be 0. For example, the student (decimal) number 99805234 will produce 11001. The user is to enter a 5-bit binary sequence one bit at a time. The five bits will be displayed on five of the seven segment displays. If the five entered bits equal to the stored binary code, then ‘E’ is to be displayed on the sixths seven- segment display. However, if the five entered bits do not equal the binary code, then ‘n’ is to bedisplayed. Note that you do not have to display bits as they are received in accumulating manner (as shown in the figure below), rather, you can display all five bits and the comparator outcome (‘E’ or ‘n’) when the fifth bit is received. All six seven-segment displays are to stay on for five seconds, then they will be erased. Once the displays are erased, the circuit will be ready for receiving a new set of five input bits.

- Reset: if pressed, the circuit will return to the initial state and all seven segment displays are to be erased.

- Input (could be received from a dipswitch in your MXK): to specify the binary input (1 or 0).

- Trigger (could be received from a pushbutton in your MXK): to allow the input to be received by the circuit.

- Clock: to alternate between the 7-segment displays (expected to be around 1000 Hz).

There are two sets of outputs, which are:

- d1, d2, ..., d7 (anodes to switch between the seven 7-segment displays)

Burnside Marketing Research conducted a study for Barker Foods on several formulations for a new dry cereal. Three attributes were found to be most influential in determining which cereal had the best taste: ratio of wheat to corn in the cereal flake, type of sweetener (sugar, honey, or artificial), and the presence or absence of flavor bits. Seven children participated in taste tests and provided the following part-worths for the attributes (see section 13.4 ):

Manager T. C. Downs of Plum Engines, a producer of lawn mowers and leaf blowers, must develop an aggregate plan given the forecast for engine demand shown in the table. The department has a regular output capacity of 140 engines per month. Regular output has a cost of $65 per engine. The beginning inventory is zero engines. Overtime has a cost of $115 per engine.

Month 1 2 3 4 5 6 7 8

Total Forecast 130 135 130 143 130 135 135 134 1,072

b. Compare the costs to a level plan that uses inventory to absorb fluctuations. Inventory carrying cost is $3 per engine per month. Backlog cost is $135 per engine per month. There should not be a backlog in the last month. Set regular production equal to the monthly average of total forecasted demand. Assume that using overtime is not an option. (Negative amounts should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Round average inventory row, Inventory cost row, and Total row values to 1 decimal.)

Periodic inventory by three methods; cost of goods sold

The units of an item available for sale during the year were as follows:

There are 60 units of the item in the physical inventory at December 31. The periodic inventory system is used.

Determine the ending inventory cost and the cost of goods sold by three methods. Round interim calculations to one decimal and final answers to the nearest whole dollar.

The table below represents the number of young people in a certain city enrolled in the academic support and enrichment program of youth services. Here, x represents the number of months from January 2011, and y represents the number of young people enrolled. Use Excel to find the best fit linear regression equation. Round the slope and intercept to two decimal places.

Expected Return and Standard Deviation / This problem will give you some practice calculating measures of prospective portfolio performance. There are two assets and three states of the economy

Expected Returns :

Stock A = (.20 * -.15) + (0.50 * .20) + (.30 * .60) = .25

Stock B = (.20 * .20) + (.50 * .30) + (.30 * .40) = .31

Standard Deviation :

Stock A = .20 * (-.15 - .25)^2 + .50 * (.20 - .25)^2 + .30 * (.60 - .25)^2 = 0.07

√0.07 = .2646, 26.46%

Stock B = .20 * (.20 - .31)^2 + .50 * (.30 - .31)^2 + .30 * (.40 - .31)^2 = 0.0049

√0.0049 = .07, 7%

Portfolio Risk and Return / Using the information in the precious problem, suppose you have $20,000 total. If you put $15,000 in Stock A and the remainder in Stock B. what will be the expected return and standard deviation of your portfolio?

**** In C++ ****Exercise #3: Design and implement a program (name it ArrayMethods), that defines 4 methods as follows: int arrayMax(int[] arr) returns the maximum value in the an array int arrayMin(int[] arr) returns the minimum value in an array void arraySquared(int[] arr) changes every value in the array to its square (value²) void arrayReverse(int[] arr) reverses the array (for example: array storing 7 8 9 becomes 9 8 7 ) The program main method creates a single-dimensional array of length 5 elements and initialize it with random integers between 1 and 100. The program displays the original array, then calls each of the above methods and displays their results as shown below. Document your code and organized your output following these sample runs. Sample run 1: Original array: 3, 5, 2, 6, 1 Max value: 6 Min value: 1 Squared array: 9, 25, 4, 36, 1 Reversed array: 1, 36, 4, 25, 9 Sample run 2: Original array: 3, 2, 3, 7, 2 Max value: 7 Min value: 2 Squared array: 9, 4, 9, 49, 4 Reversed array: 4, 49, 9, 4, 9 Sample run 3: Original array: 2, 2, 2, 2, 2 Maxvalue: 2 Min value: 2 Squared array: 4, 4, 4, 4, 4 Reversed array: 4, 4, 4, 4, 4

8. Complete the program that calculates the volume of a cube. If the side length entered for the cube is negative, the program should display an error message saying the length should be positive. If the side length entered for the cube is greater than 100, the program should print a message saying the side is too big. Otherwise the program should calculate and print the volume of the cube of the given side length.

Sample program runs are shown below: import java.util.Scanner; public class CubeVolume { public static void main(){ Scanner reader = new Scanner(System.in); System.out.print("Enter the cube side length: "); double side = reader.nextDouble();
