Assignment - Data representation & Digital logic

Task

1. Represent the following decimal numbers in both binary sign/magnitude and twos complement using 16 bits: -29.

2. A Computer uses IEEE-754 format to represent floating points. What value (in decimal) the computer represents if the floating point is represented using the following binary digits: 0 01111110 10100000000000000000000

3. X'Y + XYZ' + Y' + XZ (Y+Y') = 1

4. Charles Sturt University (CSU) academic director want to select students in Sydney Study Center to give them Gala Dinner Award. The recipient has completed three subjects at least, two of them are core and the third is elective . Before he will select him, he must check three subjects.

He has come to the following conclusions:

- Give if two of core are High Distinction (HD) and elective subject is not.
- Give if one of the core subject and elective subject are HD.
- Don't hire otherwise.

Construct a truth table and find the minimized Boolean function to implement the logic telling the director when to hire. Draw a circuit diagram for the Boolean function.

5. Complete the truth table for the following sequential circuit:

Assessment item

Task

1. A digital computer has a memory unit with 48 bits per word. The instruction set consists of 240

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 needed to specify the register?
c) How many bits are left for the address part of the instruction?
d) What is the maximum allowable size for memory?
e) What is the largest unsigned binary number that can be accommodated in one word of memory?

2. Write a MARIE program using a loop that multiplies two non-negative numbers by using repeated addition. For example, to multiply 3 x 6, the program would add 3 six times or add 6 three times. You should write and run the program using MARIE simulator. Also write the code with Address, Instruction, and Comments.

3. Consider an instruction Add 1000. Memory contents, Accumulator (AC), and R1 Register contents are depicted in the below figure: (such as memory address 1000 contains a value 1400, memory address 1100 contains a value 400 etc. All the numbers used here are decimals).

Assuming R1 is implied in the indexed addressing mode, determine the actual value loaded into the accumulator (AC) using the following addressing modes:

i) Immediate
ii) Direct
iii) Indirect
iv) Indexed
