Prompt

In this project you will design and build a simple CPU on Logisim and write programs that can run on it. If you haven’t yet, you can download Logisim by following this link: http://www.cburch.com/logisim/download.html

Your design will go through four phases. In the first phase, you will design and build the ALU using Logisim. In the second phase, you will design the instruction set that implements the instructions you designed in phase one. In the third phase, you will design and implement a control unit for this ALU using Logisim. By connecting the CPU to the ALU, you will get a functional CPU. In phase four of the project, you will write assembly language programs for the CPU you built.

Phase One

Start by building an 8-bit ALU using Logisim. This ALU can implement 16 instructions on 8-bit operands. We would suggest the following minimum list of instructions:

• Arithmetic addition
• Increment
• Decrement
• Comparison (with 3 outputs: one for equals, one for less than and one for greater than)
• Logic bitwise Not
• Logic bitwise And
• Logic bitwise Or
• Register right logic shift
• Register left logic shift

In addition to these nine instructions, please suggest five more instructions that the ALU can implement for a total of 14 instructions (we are reserving 2 instructions for branching). Justify the importance of the five instructions you added in a Word doc to submitted as part of this assignment. Label these instructions as ‘Phase One.’

After you’ve suggested and justified your five suggested instructions, please build at least the nine above-mentioned operations as blocks in Logisim.

Phase Two

In phase two of the project, you are required to design the instruction set of the ALU/CPU as follows:

• Create the opcode table for the ALU by giving a binary code and a name for each instruction you built in Logisim in phase one.
• Decide how many operands you want your instructions to handle and justify your choice. We suggest either one operand with accumulator or two operands with the result stored in one of the input registers.
• In Logisim, add a multiplexer to the circuit you built in phase one that chooses one of the available operations. The simplest way to create this part of the CPU is to connect the outputs of the multiplexer to the inputs of AND arrays connected to the output of the operation blocks.

Please record your answer to phase two in the same Word doc and label it ‘Phase Two.’

Phase Three

In phase three, you are required to use Logisim to implement the control unit for at least the following three operations:

• addition
• logic bitwise AND
• right logic shift

In order to finish this phase, you need to add operand registers according to the decision you took for the number of operands in phase two and, if needed, a flag register.

Please record your answer to phase three in the same Word doc and label it ‘Phase Three.’

Phase Four

In order to be able to write assembly language for the CPU we need to add to instructions (without implementation):

• branch to an address (name it JMP)
• conditional branch to an address (name it CJMP and suppose that the jump takes place if the comparison operation result is ‘equals’)

Now, write the following programs using the assembly language you designed in the previous phases of the project as well as these two branching additional instructions:

• Write a program that adds two operands.
• Write a program that adds operands until the new value to be added is 0. You do not need to implement the input operations to modify the contents of the registers. Just assume that by the end of each iteration, the register content is modified.
• Write a program that increments by 2 the content of a register 10 times.
• Write a program that shifts the content of a register until the least significant bit is 0. Think of a way to stop shifting if the content of the register is 11111111 and add it to your program.

Please record your programs in the same Word doc and label them under the section ‘Phase Four.’

 Week 10 Assignment – Comprehensive Project Plan and Executive Presentation

Overview

This is the fifth and final course project deliverable in the series of five sequential assignments in this course. You are continuing on in your role as the CTO of a hypothetical e-commerce start-up company of your design.

Throughout the course, you have been working on delivering an information technology project plan in anticipation of the company relocating to a new facility.

• In the first course project deliverable, you created a project plan inception document and supporting Gantt chart.
• In the second course project deliverable, you developed the business requirements to be incorporated into the information systems design you are creating. You also updated your original supporting Gantt chart based on major and minor tasks identified in the business requirements document.
• In the third course project deliverable, you created an infrastructure design that considered the key elements of software, hardware, security, and business process flow for your e-commerce startup company. Once again you updated the supporting Gantt chart based on the major and minor tasks identified in the infrastructure design document.
• In the fourth course project deliverable you developed the system implementation document. This document spelled out the EFI technical aspects of your e-commerce company’s information systems infrastructure. Again you updated the supporting Gantt chart to reflect the major and minor tasks identified in the system implementation document.

You are now in the final stage of the project plan development. You will leverage all previous deliverables and integrate them into one document that will serve as the project’s statement of work.

Your goal is for the start-up company’s executive team and the venture capital group to approve and fund your project. The detailed project plan is necessary to accomplish the monumental implementation task. The executive team and investors, however, are only interested in an executive summary in the form of a 10–15-slide PowerPoint presentation. As a result, you are required to create a compelling PowerPoint presentation, supported by the detail in your project plan, which convinces the executive group that your solution is optimal.

This assignment consists of three parts:

Part 1: Comprehensive Project Plan

You will create an 8–10-page final comprehensive project plan. This document will distill down the most salient points from each of the four previous course deliverables into one integrated, cohesive comprehensive project plan that persuades investors of the recommended approach.

Critical Note: Do NOT simply combine the previous four assignments into one 30–50-page document. Instead, your task is to:

• Review each of the four previous assignments.
• Select the most critical information from each that investors need to know to make an informed investment decision.
• Summarize the information you selected.
• Ensure that the selected information flows from one section to the next in a cohesive and compelling fashion.

Part 2: Executive Presentation

You will create a 10–15-slide compelling executive presentation that convinces the start-up company’s executive team and potential investors to invest in the company. Your recommended solution is the one that can grow this $5 million dollar e-commerce start-up company into a $30 million dollar company within the next two years.

Part 3: Updated Final Gantt Chart

You will use Microsoft Project to update the supporting project Gantt chart begun in your first course project deliverable.

• You are not creating a new Gantt chart, only updating the one you created in the previous assignment to produce the final project Gantt chart to include all major and minor tasks necessary to execute the project.

Note:

• You are to create or assume all necessary assumptions to successfully complete this assignment.
• You must submit all three parts as separate files to the assignment area. Label each file name according to the appropriate part.

Instructions 

Part 1: Comprehensive Project Plan

You are to write a comprehensive 8–10-page comprehensive, final project plan in which you:

1. Describe the project’s goals, objectives, scope, and control measures.
2. Relate the value of the proposed solution to the competitive advantage that information technology will afford the e-commerce company.
3. Provide a rough estimate of the entire project’s cost, including hardware, software, and labor.
   • The work you did to create the bill of materials in the fourth course project deliverable will help you with this.
4. Use three sources to support your writing.
   • Choose sources that are credible, relevant, and appropriate.
   • Cite each source listed on your source page at least one time within your assignment.
   • Access the library or review library guides for help with research, writing, and citation.

Part 2: Executive Presentation

You are to create a 10–15-slide executive PowerPoint presentation to persuade potential investors to invest in your e-commerce start-up company. In your presentation you are to:

1. Illustrate the concepts from your 8–10-page comprehensive project plan in an executive presentation.
2. Create bulleted speaking notes to the executive board in the Notes section of your PowerPoint presentation.

Note:

• Create or assume any fictitious names, data, or scenarios that have not been established in this assignment for a realistic flow of communication.
• Consider including images, graphics, charts, tables, etc. in your presentation to increase audience engagement.

Part 3: Updated Gantt Chart

Use Microsoft Project to update the previous Gantt chart to produce the final project Gantt chart to include all major and minor tasks necessary to execute the project.
