Answer to Question #245267 in Electrical Engineering for anshu

Question

In an assignment given on CSE211, a student is assigned the following task 1. Consider AR= last digits of your registration no 2. Place your date of birth including your date and month of birth into the TR eg: 0108 – 01 date and 08 as month M[AR]  TR IR M[AR] 

Answer 1

Part 1:

Taking the student’s registration number to be:

117/78013/2020

We can execute this task as follows:

We begin by low-order leaving:

With the specifications:

AR ß PC

M[AR] ßDR

IRß M[AR]

We determine that the program counter (PC) will require 12-bits to execute this task

Therefore,

Number of words = 256K words = 28 *210 words Number of bits pre each word = 32 bit = 25 bit Number of registers = 64 bit = 26 Register a) operation code = 7 bits, register code = 6 bits, address part = 18 bits

Part 2: With a PC = 789 H , the CPU will fetch the instruction(binary code) from memory using common bus system by using a bus which is constructed using multiplexer of equal capacity like a 4-unit. This will enable a set of registers to share a common bus for data transfer. Data Transfer Using the Bus.
