1) Create a folder named pgm2

2) In this folder (pgm2) place the text file located at:

http://users.cis.fiu.edu/~mrobi002/databases/RAMerrors8x4

Each record in this file represents the location of an error found in RAM

3) Assume you have a computer with 32 gigs of RAM, each 4 gigs in a

different memory chip, therefore you have 8 (eight) 4 gigs RAM chips.

---------- decimal address ---------- GIGs

RAM chip 0 contain addresses: 0 - 34,359,738,368 bits = 4

RAM chip 1 contain addresses: 34,359,738,369 - 68,719,476,738 bits = 8

RAM chip 2 contain addresses: 68,719,476,739 - 103,079,215,108 bits = 12

RAM chip 3 contain addresses:103,079,215,109 - 137,438,953,478 bits = 16

RAM chip 4 contain addresses:137,438,953,479 - 171,798,691,848 bits = 20

RAM chip 5 contain addresses:171,798,691,849 - 206,158,430,218 bits = 24

RAM chip 6 contain addresses:206,158,430,219 - 240,518,168,588 bits = 28

RAM chip 7 contain addresses:240,518,168,589 - 274,877,906,958 bits = 32

I used this link to do the calculations:

http://www.matisse.net/bitcalc/?input_amount=274%2C877%2C906%2C958&input_units=bits¬ation=legacy

4) In the same folder (pgm2), in terminal mode, using an editor, create a

Java program:

5) Open the text file ( named on question 2 above )

6) Read each record, which is the location of an error in RAM, in hex

7) Convert that hex value to binary

8) Convert the binary value to decimal value

9) Print the RAM chip number where the error is located for each record

as follows:

Error Found at

hex number = binary number = decimal number = chip number

note: Location addresses for RAM chips are decimal

*** DO NOT CHANGE THE FILE NAME

*** MAKE SURE THE FILE IS IN THE SAME FOLDER AS YOUR JAVA PROGRAM

*** CREATE YOUR OWN METHODS THAT WILL CONVERT HEX TO BINARY AND BINARY TO DECIMAL

*** DO NOT USE JAVA'S AUTOMATIC CONVERSION METHODS

*** DO NOT USE JAVA'S PARSE COMMAND

*** USE System.out.printf commands ONLY to print any data
