Some organizations prohibit workers from bringing certain kinds of devices into the workplace, such as cameras, cell phones, and USB drives. Some businesses require employees to use clear or see-through backpacks when carrying personal items. What other devices might not be allowed in certain facilities, and why would they be restricted?

After you have complete the IBM DB2 tutorial, use the image below to create a voice tutorial using screen cast-o-matic.  The tutorial should explain how to create a DB2 database using IBM’s cloud.   Please note, you must use the IBM cloud account you created in week one.  

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 CU 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.’

Hide Assignment InformationInstructions

This week, you will submit the one- to two-page executive summary that you started last week. This summary is for the owner of Don & Associates, where you are employed in this scenario.

Use this Executive Summary Template. In the template, you will see specific instructions. Delete the instruction text before you submit the project.

Your summary should include:

• the types of cloud computing (private, public, hybrid)
• three major cloud service providers
• three cloud computing service models
• potential benefits and risks of migrating the company’s technical infrastructure to the cloud

Be sure to cite any sources you use.

How Will My Work Be Evaluated?

For this assignment, you are asked to provide your supervisor with a summary of cloud computing and the potential benefits and risks of migrating to the cloud. By summarizing your findings in a brief executive summary, you are showing how you use your technical knowledge to convey your ideas to others in a professional setting. Your ability to express your findings using the right mix of technical detail in a business context is an important workplace skill.

The following evaluation criteria aligned to the competencies will be used to grade your assignment:

• 1.1.1: Articulate the main idea and purpose of a communication.
• 1.1.2: Support the main idea and purpose of a communication.
• 1.1.3: Present ideas in a clear, logical order appropriate to the task.
• 1.2.1: Identify the target audience, the context, and the goal of the communication.
• 1.2.2: Employ a format, style, and tone appropriate to the audience, context, and goal.
• 1.3.1: Identify potential sources of information that can be used to develop and support ideas.
• 1.4.1: Produce grammatically correct material in standard academic English that supports the communication.
• 1.4.2: Use vocabulary appropriate for the discipline, genre, and intended audience.
• 10.1.1: Identify the problem to be solved.
• 10.1.2: Gather project requirements to meet stakeholder needs.
