Answer:
The code is given below in Java with appropriate comments
Explanation:
//Import the input.
import java.util.Scanner;
class CensoredWords
{
//Define the main method.
public static void main(String args[ ])
{
//Define the variables.
String userInput="" ;
//Define the scanner object
Scanner scobj = new Scanner(System.in);
//Accept the userInput.
System.out.print("Enter String: ");
userInput=scobj.nextLine();
//Check if the input contains darn.
//Print censored.
if(userInput.toUpperCase().indexOf("DARN") != -1)
System.out.printf("Censored");
//IF the input does not contains darn
//Print userInput.
else
System.out.printf(userInput)
return;
}
}
Answer:
1. 2588672 bits
2. 4308992 bits
3. The larger the data size of the cache, the larger the area of memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.
Explanation:
1. Number of bits in the first cache
Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))
total bits = 2^15 (1+14+(32*2^1)) = 2588672 bits
2. Number of bits in the Cache with 16 word blocks
Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))
total bits = 2^13(1 +13+(32*2^4)) = 4308992 bits
3. Caches are used to help achieve good performance with slow main memories. However, due to architectural limitations of cache, larger data size of cache are not as effective than the smaller data size. A larger cache will have a lower miss rate and a higher delay. The larger the data size of the cache, the larger the area of memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.
