Homework

The problems from the textbook are from the Exercises section of Chapter 4.

1. How many bits are required to address a 4M x 16 main memory if a) main memory is byte addressable?

b) main memory is word addressable? (For part b, assume a 16-bit word.)

2. How many 256x8 RAM chips are needed to provide a memory capacity of 4096 bytes?

a) How many bits will each address contain?

b) How many lines must go to each chip?

c) How many lines must be decoded for the chip select inputs? Specify the size of the decoder.

3. A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.

a) How many bits are needed for the opcode?

b) How many bits are left for the address part of the instruction?

c) What is the maximum allowable size for memory?

d) What is the largest unsigned binary number that can be accommodated in one word of memory?

4. Section 4.10 (attached) of the text provides an example of the execution of a simple MARIE program.

For this problem, you are to complete a similar example for a different program. In particular, for the MARIE program given below, you are to complete the equivalent of Figure 4.14, but for the program below. You do not need to show how the "Halt" instruction is executed. Specify values in PC, IR, MAR, MBR, and AC in hexadecimal. A template for your answer is provided as a Microsoft Word file that is included with this assignment. You are to incorporate your answer for this problem into your submission for the homework assignment.

5. Scavenger Hunt: Two pioneers of early computers and computer organization were Howard H. Aiken and John von Neumann. Answer the questions below regarding Aiken and von Neumann. Cite sources used for your answers.

a. Is Aiken or is von Neumann associated with the so-called Princeton architecture?

b. Is Aiken or is von Neumann associated with the so-called Harvard architecture?

c. What is the key feature of a Princeton architecture computer compared to the Harvard architecture?

d. Does the MARIE architecture owe more to Aiken or von Neumann? Briefly justify your answer.

All the information needed to do the homework is attached in the word document. I've also included the MARIE simulator as another file you might need to complete the homework assignment. You can also go to this website: JONES & BARTLETT LEARNING, click on sample materials and then the MARIE simulator to download the simulator if these files that are uploaded isn't enough. This homework is all about MARIE: An Introduction to a Simple Computer. I know that there is a tight window, but please help me!

Solutions must be clear and presented in the order assigned. Solutions must show work needed, as appropriate, to derive your answers. Written answers should be concise, but sufficiently complete to answer the question. Neat hand drawings, where needed, are acceptable. Your final solution for each problem must be easily identified.
