Abstract Any encryption or decryption method will have certain key based on which the encoding and decoding will be performed. This is done to avoid access of data by unauthorized personal. Without the decoding key, encoded data is junk. Similarly, Federal Information Processing Standard (FIPS) developed Advanced Encryption Standard, which was used for saving digital data especially in magnetic tape like debit cards and credit cards, so that it provides security for the details and also this can be used in security of PDA’s which need to work very efficiently with high speed encoding and decoding and also need to consume less area as possible. It can be built using purely hardware or purely software i.e. using programming language such as Verilog. Decryption and Encryption has main part, Mix Columns and Inverse Mix columns, on which the whole AES operation depends. Here synthesis is performed for the decryption unit of the AES, which can be performed in two methods i.e. Look-up Table and Splitting method. Comparison of two methods is done by synthesizing the program in Spartan -3E of Xilinx ISE 14.1 Suite. Keywords: Encryption, Decryption, FIPS, Mix Columns, Inverse Mix Columns.

Design and implementation of single bit error correction linear block code sy...TELKOMNIKA JOURNAL
Linear block code (LBC) is an error detection and correction code that is widely used in
communication systems. In this paper a special type of LBC called Hamming code was implemented and
debugged using FPGA kit with integrated software environments ISE for simulation and tests the results of
the hardware system. The implemented system has the ability to correct single bit error and detect two bits
error. The data segments length was considered to give high reliability to the system and make an
aggregation between the speed of processing and the hardware ability to be implemented. An adaptive
length of input data has been consider, up to 248 bits of information can be handled using Spartan 3E500
with 43% as a maximum slices utilization. Input/output data buses in FPGA have been customized to meet
the requirements where 34% of input/output resources have been used as maximum ratio. The overall
hardware design can be considerable to give an optimum hardware size for the suitable information rate.
We all make mistakes while programming and spend a lot of time fixing them.
One of the methods which allows for quick detection of defects is source code static analysis.

I need help coming up with a MIPS program for this.1.3. Overvi.pdfpratyushraj61
I need help coming up with a MIPS program for this.
1.3. Overview
For this assignment you will be writing a program the asks the user to enter a decimal number
and stores it in IEEE 754 single-precision floating point representation. You will then parse the
IEEE 754 representation to extract the different pieces (sign, exponent, and significand)
You do not have to convert the input to IEEE 754 representation manually. Just use the syscall to
read a float. This will automatically store the value in IEEE 754 format for you. You can then
copy the value to a normal 32-bit register to perform the different bit manipulations to extract
each piece.
After the initial reading in of the floating point value and moving the value to a standard register
you should not use the floating point registers again. Do not use any of the floating point
operations to find the sign, or anything else.
All of the parsing and calculations should be done using various bit manipulations operations
(i.e. bitshifts, maskings, etc). Remember beyond the initial reading of the floating point value
and moving it to a standard register your program should not touch the floating point registers
again.
Your program does not need to handle any of the special cases of floating point numbers like
NaN, infinity, -infinity, 0 or -0.
1.4. Task 1: Main Procedure
Your first task is to collect is to create a loop for your program. Ask user to enter "Do you want
to do it again?" in a Dialog box. Hint: Use syscall 50. If the user answers YES repeat the process.
NO or Cancel, exit the program.
1.5. Task 2: Take User Input Procedure
void read_float()
Next, take user input and store it in memory. Prompt the user to enter a floating point value as a
decimal number. Then, store the input value in a single precision floating point register. In a
DialogBox (syscall 52), Display a string with info about the program ex: "Welcome to the " and
capture a user input. The input should be a floating point number.
You MUST store input into memory space (ieee). To do this, first move your captured input
from the f0 floating point register to a regular temporary register using the following call:
Now, you should be able to store the value into the ieee variable in memory.
The procedure should have the following signature:
1.6. Task 3: Print the sign
void print_sign(ieee)
Your next task is to create a procedure called print_sign that will extract and interpret the sign bit
of the IEEE 754 single precision floating point number. The floating point number is the value
you collected from Task 2.
Your function will take the value as a 32-bit number in a non-floating point register (i.e. $a0).
Remember, this value is stored in your ieee memory space. You should use bit manipulations
(i.e. shifting, masking, etc) to determine the value of the sign bit. If the sign bit is a 1 your
function should print the '-' character. If it is a 0 your function should print the '+' character.
The procedure should have the followi.

Problem 1 (35 pts): IMEI (International Mobile Equipment Identifier)
Every mobile phone operating in wireless networks is characterized by a unique identifier
of 15 digits, called IMEI
(https://en.wikipedia.org/wiki/International_Mobile_Station_Equipment_Identity)
A method to check if the device is really made by the official manufacturer is to compare the
IMEI’s last digit, called Luhn digit, with a check digit. If the Luhn digit is equal to the check
digit, the device is most probably authentic. Otherwise, it is not authentic for sure.
The check digit is calculated as follows:
1) First, we calculate the SUM of the first IMEI’s 14 digits by adding
a) the digits in the odd positions (meaning even index for the array in C)
b) the double of the digits in the even positions. But if the double of the digit is a two-digit
number, we add each digit separately. For example, suppose that the value of the digit is 8,
its double is 16. We therefore add to the SUM the result of 1+6 = 7 (not 16).
2) If the last digit of the calculated SUM is 0, that is the check digit. If not, we subtract the
last digit of the calculated SUM from 10 and that is the check digit.
For example: let’s check the IMEI 357683036257378.
Note: the last digit of the given IMEI above is 8 which is the Luhn digit.
Apply the above algorithm (by hand) to the first 14 digits, we get
3 + (2x5) +7 + (2x6) + 8 + (2x3) + 0 + (2x3) + 6 + (2x2) + 5+ (2x7) + 3+ (2x7)
3 + (10) +7 + (12) + 8 + (6) + 0 + (6) + 6 + (4) + 5+ (14) + 3+ (14)
3 + (1+0) +7 + (1+2) + 8 + (6) + 0 + (6) + 6 + (4) + 5+ (1+4) + 3+ (1+4)
3 + (1) +7 + (3) + 8 + (6) + 0 + (6) + 6 + (4) + 5+ (5) + 3+ (5)
= 62
Then the check digit = 10 – 2 = 8.
Since the check digit (=8) is equal to the Luhn digit (=8), this IMEI is valid. 2
2. Write a C program that
- Prompt the user to enter the 15 digits of IMEI separated by spaces. The program should
store the digits in an integer array.
- Display the sum of the first 14 digits using the algorithm on the previous page
- Calculate and display the check digit, and
- Compare it to the Luhn digit. If they match, output with the message “IMEI is valid.” If not,
output with the message “IMEI is invalid”.
Sample Code Execution: Digits are entered by a user
Enter 15-digit barcode (separate each digit by space)
3 5 7 6 8 3 0 3 6 2 5 7 3 7 8
total sum of 14 digits = 62
check digit = 8
IMEI is valid
Enter 15-digit barcode (separate each digit by space)
3 5 7 6 1 3 0 0 4 4 4 8 4 8 5
total sum of 14 digits = 55
check digit = 5
IMEI is valid
Enter 15-digit barcode (separate each digit by space)
4 9 0 1 5 4 2 0 3 2 3 7 5 1 9
total sum of 14 digits = 52
check digit = 8
IMEI is invalid
Enter 15-digit barcode (separate each digit by space)
0 1 2 6 4 6 0 0 0 8 2 7 7 6 2
total sum of 14 digits = 38
check digit = 2
IMEI is valid
Enter 15-digit barcode (separate each digit by space)
3 5 2 2 5 5 0 1 0 1 3 2 8 3 7
total sum of 14 digits = 41
check digit = 9
IMEI is invalid 3

For this problem, we want to determine number and location of peaks in the terrain, where
a peak is a point that has lower elevations all around. We also want to determine the highest
peak and its location.
