Program Description Answer

In an array declaration, “size declarator” indicates the number of elements that the array will have.

Hence, the correct answer is option “B”.

Expert Solution & Answer

Explanation of Solution

Size declarator:

In an array the “size declarator” must be a non-negative integer expression. It may be a variable or a literal value. It is a common practice to use a final variable as a size declarator.

Example:

final int NUM_ELEMENTS = 6;

int[] numbers = new int[NUM_ELEMENTS];

Explanation for wrong answers:

a.Subscript:

A “subscript” is used as an index to pinpoint a specific element within an array.

Hence, the option “A” is wrong.

c.element sum:

The “element sum” is used to add the numbers of element in an array.

Hence, the option “C” is wrong.

d.Reference variable:

The user declare a “reference variable” and use the new keyword to create an instance of the array in memory. The reference variable can be declared as follows:

numbers = new int[6];

Hence, the option “D” is wrong.

Q.1. Architecture performance [10 marks] Answer A certain microprocessor requires either 2, 4, or 6 machine cycles to perform various operations. ⚫ (40+g+f)% require 2 machine cycles, ⚫ (30-g) % require 4 machine cycles, and ⚫ (30-f)% require 6 machine cycles. (a) What is the average number of machine cycles per instruction for this microprocessor? Answer (b) What is the clock rate (machine cycles per second) required for this microprocessor to be a "1000 MIPS" processor? Answer (c) Suppose that 35% of the instructions require retrieving an operand from memory which needs an extra 8 machine cycles. What is the average number of machine cycles per instruction, including the instructions that fetch operands from memory?

Q.2. Architecture performance [25 marks] Consider two different implementations, M1 and M2, of the same instruction set. M1 has a clock rate of 2 GHz and M2 has a clock rate of 3.3 GHz. There are two classes of instructions with the following CPIs: Class A CPI for M1 CPI for M2 2.f 1.g B 5 3 C 6 4 Note that the dots in 2 fand 1.g indicate decimal points and not multiplication. a) What are the peak MIPS performances for both machines? b) Which implementation is faster, if half the instructions executed in a certain program are from class A, while the rest are divided equally among classes B and C. c) What speedup factor for the execution of class-A instructions would lead to 20% overall speedup? d) What is the maximum possible speedup that can be achieved by only improving the execution of class-A instructions? Explain why. e) What is the clock rate required for microprocessor M1 to be a "1000 MIPS" (not peak MIPS) processor?
