Bitwise operations allow manipulating individual bits within binary representations of data. Common bitwise operations include AND, OR, NOT, and shifting bits left or right. Bitmasks are used to isolate specific bits for setting, clearing, or reading their values. Bitwise logic is applied extensively in areas like graphics, embedded systems, data structures, and networking where individual bits need to be manipulated.
The document discusses the arithmetic logic unit (ALU) and its operations. It describes:
1) The ALU performs basic arithmetic operations like addition, subtraction, incrementing and decrementing on numeric data stored in registers.
2) Binary adders and adder-subtractors are used to implement addition and subtraction operations. They are built by connecting full adders in series.
3) An arithmetic circuit can perform the basic arithmetic operations as well as logic operations by setting control signals appropriately.
4) A status register is used to store flags indicating the results of arithmetic and logic operations like carry, overflow, zero etc. This allows instructions to conditionally execute based on previous results.
Signed and unsigned variables can represent positive and negative numbers, or just positive numbers respectively. Declaring a variable as unsigned increases its maximum positive range. Storage classes like auto, static, extern and register provide information about a variable's location and visibility. Bitwise operators operate on binary representations of numbers and are commonly used for tasks like compression/encryption that require bit-level manipulation.

project ppt on anti counterfeiting technique for credit card transaction systemRekha dudiya
CREDI-CRYPT is a technique that hides sensitive credit card information in a background image using both cryptography and steganography. It encodes credit card details like the card number and CVV using techniques like arithmetic coding and Hamming codes. The encoded text is then embedded into the pixel coefficients of the cover image using an integer wavelet transform and optimal pixel adjustment. This ensures confidentiality and integrity of credit card transactions while transmitting payment details over unsecured networks. The system was designed to be used as a standalone application by small to medium banks and organizations for securely storing credit card data without network transfer.
This document provides an overview of data representation in computers. It discusses binary, decimal, hexadecimal, and floating point number systems. Binary numbers use only two digits, 0 and 1, and can represent values as sums of powers of two. Decimal uses ten digits from 0-9. Hexadecimal uses sixteen values from 0-9 and A-F. Negative binary integers can be represented using ones' complement or twos' complement methods. Twos' complement avoids multiple representations of zero and is commonly used in computers. Converting between number bases involves expressing the value in one base using the digits of another.
The document discusses code generation in compiler design. It describes code generation as the final phase of a compiler that takes an intermediate representation and symbol table as input and produces semantically equivalent target program code. The main tasks of the code generator are instruction selection, register allocation and assignment, and instruction ordering. Issues in designing the code generator include producing correct code, handling different types of intermediate representations and target architectures. The document also provides examples of techniques for register allocation, basic block partitioning, control flow graphs, DAG representations, and optimizing register usage.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
2. Introduction
• Bit manipulation is the act of
algorithmically manipulating bits or other
pieces of data shorter than a word.
• Computer programming tasks that require bit
manipulation include low-level device control,
error detection and correction algorithms,
data compression, encryption algorithms, and
optimization.
3. • a single bit can store all the information needed for a computation.
• For example, a file can be write-protected, or not. A user can be
logged in, or not. A program can be currently running, or not.
• In many advanced algorithms, bits are frequently used in
computations and data structures. For example,
compression/decompression routines (codecs) commonly
manipulate bit patterns to reduce the necessary storage size.
Sorting methods commonly use trees and other binary structures
during operation. Bitwise operations are also common in device
drivers and graphics programming.
• In the C language, the smallest data type available is the char, which
is 1 byte (8 bits). To manipulate a single bit, you can
– use an entire char to store the single bit. This is of course wasteful
and, if used indiscriminately, would seriously raise the amount of
memory necessary to operate a modern computing system.
– figure out how to manipulate just 1 bit within a char, or within any
other data type. In the C language, this is accomplished using bitwise
operations.
4. Binary Logic Operations
• a single bit can have a value of either 1 or 0, which can also
represent true or false.
• The three most basic logic operations are AND, OR, and NOT. The
operations work as follows:
AND OR NOT
0 AND 0 = 0 0 OR 0 = 0 NOT 0 = 1
0 AND 1 = 0 0 OR 1 = 1 NOT 1 = 0
1 AND 0 = 0 1 OR 0 = 1
1 AND 1 = 1 1 OR 1 = 1
The result of an AND operation is true only if both input values are
true.
The result of an OR operation is true if either input value is true.
The result of a NOT operation is to reverse the bit value.
• Logic operations are independent of any particular programming
language used to implement them.
• There are several other logic operations, for example NOR and
NAND, which are commonly used in circuits.
5. Bit Operators
• Bit operators are the symbols or syntax used in a programming
language to affect individual bits within a variable.
• In the C programming language, there are six bit operators:
Operator Symbol name Action
~ tilde bitwise NOT
& ampersand bitwise AND
| vertical bar bitwise OR
^ caret bitwise XOR
>> greater-than greater-than right-shift
<< less-than less-than left-shift
• The bit operators are intended to be used only on the whole
number data types, char and int, and the related extensions (e.g.,
unsigned char).
• Although bits can be manipulated in any variable, it is rare to see bit
operators applied to the real number data types.
6. • The bitwise NOT operator inverts every bit in a
variable. It is written using the tilde symbol (~).
For example:
unsigned char a;
a=17;
a=~a;
printf("%dn",a);
• The result of executing this code is:
238
• At the bit level, the result of the code is:
C code Bits in variable a Base 10 value
a=17; 0 0 0 1 0 0 0 1 17
7. • The bitwise AND operator performs an AND between two variables,
independently at every bit. It is written using the ampersand
symbol (&). For example:
unsigned char a,b;
a=17;
b=22;
a=a & b;
printf("%dn",a);
• The result of executing this code is:
16
• At the bit level, the result of the code is:
C code Bits in variable a Base 10 value
a=17; 0 0 0 1 0 0 0 1 17
b=22; 0 0 0 1 0 1 1 0 22
• NOTE:Prior to the bitwise AND, only one bit position had a value of
1 in both variables a and b. Therefore, after the bitwise AND, this is
the only bit position with a value of 1.
8. • The bitwise OR operator performs an OR between two variables,
independently at every bit. It is written using the vertical bar
symbol (|). For example:
unsigned char a,b;
a=17;
b=22;
a=a | b;
printf("%dn",a);
• The result of executing this code is:
23
• At the bit level, the result of the code is:
C code Bits in variable a Base 10 value
a=17; 0 0 0 1 0 0 0 1 17
b=22; 0 0 0 1 0 1 1 0 22
a=a | b; 0 0 0 1 0 1 1 1 23
NOTE: After the bitwise OR, the variable a has a value of 1 in any bit
position in which either of the two input variables a or b had a value of
1.
9. • Like the arithmetic or logic operators in C, the bit
operators can be applied to either variables or
constants. For example:
char x,y;
x=7;
y=6;
x=x&y;
y=x|16;
printf("%d %dn",x,y);
• The result of executing this code is:
6 22
10. • The left-shift and right-shift bit operators move bits into higher-
order and lower-order bit positions, respectively.
• A left-shift is written in C using two consecutive less-than symbols
(<<) and a right-shift is written using two consecutive greater-than
symbols (>>).
• The value following the shift operator indicates how many bit
positions to move.
• For example:
unsigned char a,b;
a=17;
a=a << 2;
b=64;
b=b >> 3;
printf("%d %dn",a,b);
• The result of executing this code is:
68 8
• Any bits that move beyond the highest or lowest available bit are
discarded.
11. • The new bit values that take up residence in the now vacated bit positions
are given values that depend upon the bit model used by the variable.
• For a magnitude-only bit model, the new bit values are always zero, as
shown above.
• For a two’s complement bit model, the new bit values are zero for left-
shifts, and copies of the original highest-order bit for right-shifts.
• The latter maintains the original sign of the value, while shifting the
negative number in a manner synonymous with positive numbers. For
example:
char a,b;
a=17;
a=a >> 2;
b=-65;
b=b >> 2;
printf("%d %dn",a,b);
The result of executing this code is:
4 -17
• At the bit level, the result of the code is:
C code Bits in variable a Base 10 value
a=17; 0 0 0 1 0 0 0 1 17
a=a >> 2; 0 0 0 0 0 1 0 0 4
b= -65; 1 0 1 1 1 1 1 1 −65
b=b >> 2; 1 1 1 0 1 1 1 1 −17
12. Bitmask Operations
• Bitmasking is perhaps the most common type of bitwise
operation.
• It involves using a bitmask to change or query one or more
designated bits within a variable.
• The bitmask indicates which bits are to be affected by the
operation. The idea is to operate on a variable, changing
or affecting only the bits indicated by the bitmask:
variable→bitmask (bit N)→variable (only bit N changed)
• The bitmask indicated that bit N should be changed (N is
the bit position, which is also the power of 2 of the bit).
13. • The following are examples of bitmasks for an 8-bit variable (e.g., unsigned char):
Bitmask Base 10 value Indicated bits to work on
0 0 0 0 0 0 0 1 1 bit 0
0 0 0 1 0 0 0 0 16 bit 4
1 0 1 0 1 1 0 0 172 bits 2, 3, 5, and 7
• A bitmask can indicate that any number of bits are to be affected.
• The three most common bitmask operations work on a single bit: set the bit, clear
the bit, or query the value of the bit. Each of these operations can be
accomplished through the following logic:
Operation Logic
set Nth bit x = x OR 2N
clear Nth bit x = x AND NOT(2N)
read Nth bit = x AND 2N
• The act of setting a bit gives the bit a value of 1, regardless of its initial value. it
leaves all the other bits unchanged.
• The act of clearing a bit gives the bit a value of 0, regardless of its initial value, and
leaves all the other bits unchanged.
• The act of querying a bit determines the current value of a bit, leaving all bit values
unchanged.
14. • Each of these operations can be implemented in
C as follows:
Operation C code
set Nth bit x = x | (1<<N);
clear Nth bit x = x & (~(1<<N));
read Nth bit (x & (1<<N)) >>N
• When reading the Nth bit, the final right-shift
operation results in a value of 1 or 0 regardless of
which bit is being read. Without that final right-
shift, the read value will be equal to the value of
the bit position (the power of 2 of the bit place).
15. • The following code demonstrates setting, clearing, and reading bits:
char a;
int i;
a=17;
a=a | (1 << 3); /* set 3rd bit */
printf("%dn",a);
a=a & (~(1<<4)); /* clear 4th bit */
printf("%dn",a);
for (i=7; i>=0; i--)
printf("%d ",(a&(1<<i)) >> i); /* read i’th bit */
printf("n");
• The result of executing this code is:
25
9
0 0 0 0 1 0 0 1
• At the bit level, the result of the code is:
C code Operation Bits in variable a Base 10 value
a=17; 0 0 0 1 0 0 0 1 17
a=a | (1 << 3); set bit 3 0 0 0 1 1 0 0 1 25
a=a & (~(1 << 4)); clear bit 4 0 0 0 0 1 0 0 1 9
16. Applications of bit operations:
1. They are widely used in areas of graphics ,specially
XOR(Exclusive OR) operations.
2. They are widely used in the embedded systems, in
situations, where we need to set/clear/toggle just one
single bit of a specific register without modifying the
other contents. We can do OR/AND/XOR operations
with the appropriate mask for the bit position.
3. Data structure like n-bit map can be used to allocate
n-size resource pool to represent the current status.
4. Bits are used in networking, framing the packets of
numerous bits which is sent to another system
generally through any type of serial interface.
