Booth's algorithm is a method for multiplying two signed or unsigned integers in binary representation more efficiently than straightforward algorithms. It uses fewer additions and subtractions by representing the multiplicand as 2's complement numbers. The algorithm loads the multiplicand and multiplier into registers, initializes a third register to 0, and performs bitwise shifts and arithmetic operations (addition/subtraction of the multiplicand) on the registers based on the values of bits from the multiplier. This process builds up the product one bit at a time in a third register.
The document discusses recursion, including:
1) Recursion involves breaking a problem down into smaller subproblems until a base case is reached, then building up the solution to the overall problem from the solutions to the subproblems.
2) A recursive function is one that calls itself, with each call typically moving closer to a base case where the problem can be solved without recursion.
3) Recursion can be linear, involving one recursive call, or binary, involving two recursive calls to solve similar subproblems.
Assembly language is a low-level programming language that corresponds directly to a processor's machine language instructions. It uses symbolic codes that are assembled into machine-readable object code. Assembly languages are commonly used when speed, compact code size, or direct hardware interaction is important. Assemblers translate assembly language into binary machine code that can be directly executed by processors.
Real numbers can be stored using floating point representation, which separates a real number into three parts: a sign bit, exponent, and mantissa. The exponent indicates the power of the base 10 that the mantissa is multiplied by. Common standards like IEEE 754 define single and double precision formats that allocate more bits for higher precision at the cost of range. Summarizing a floating point number involves determining the exponent by shifting the decimal, converting the number to a leading digit mantissa, and writing the sign, exponent, and mantissa based on the specified precision format.
Graph traversal techniques are used to search vertices in a graph and determine the order to visit vertices. There are two main techniques: breadth-first search (BFS) and depth-first search (DFS). BFS uses a queue and visits the nearest vertices first, producing a spanning tree. DFS uses a stack and visits vertices by going as deep as possible first, also producing a spanning tree. Both techniques involve marking visited vertices to avoid loops.
This document provides an overview of first-order logic for knowledge representation in artificial intelligence. It discusses the syntax and semantics of first-order logic, including predicates, quantifiers, and variables. It also describes the knowledge engineering process for developing a first-order logic knowledge base, including identifying the problem domain, encoding general domain knowledge as rules, and representing a specific problem instance. Queries can then be posed to the knowledge base to infer answers using logical reasoning techniques like forward chaining and backward chaining.
This presentation discusses different types of microoperations that can be performed on data stored in registers. It describes arithmetic microoperations like addition, subtraction, and increment/decrement. Logic microoperations perform bit-wise operations on registers like selective set, clear, complement, and masking. Shift microoperations serially transfer data in a register left or right through logical, circular, and arithmetic shifts. Arithmetic shifts preserve a number's sign during multiplication and division by 2 during left and right shifts.

Binary search trees (BSTs) are data structures that allow for efficient searching, insertion, and deletion. Nodes in a BST are organized so that all left descendants of a node are less than the node's value and all right descendants are greater. This property allows values to be found, inserted, or deleted in O(log n) time on average. Searching involves recursively checking if the target value is less than or greater than the current node's value. Insertion follows the search process and adds the new node in the appropriate place. Deletion handles three cases: removing a leaf, node with one child, or node with two children.
The document discusses different algorithms for clipping polygons and lines to a viewing window, including the Sutherland-Hodgman and Weiler-Atherton polygon clipping algorithms. The Sutherland-Hodgman algorithm clips polygons by processing edges against each window boundary edge but can result in disconnected line segments or extraneous lines for concave polygons. The Weiler-Atherton algorithm addresses this by following either the polygon or window boundary depending on if the vertex pair is outside to inside or vice versa.

The document discusses syntax-directed translation of code into three-address code. It defines semantic rules for generating three-address code for expressions, boolean expressions, and control flow statements. Temporary variables are generated for subexpressions and intermediate values. The semantic rules specify generating three-address code statements using temporary variables. Backpatching is also discussed as a technique to replace symbolic names in goto statements with actual addresses after code generation.

It outlines the hardware and software requirements to run the experiments and provides background, algorithms, sample programs and outputs for each experiment.
An instruction format consists of bits that specify an operation to perform on data in computer memory. The processor fetches instructions from memory and decodes the bits to execute them. Instruction formats have operation codes to define operations like addition and an address field to specify where data is located. Computers may have different instruction sets.
Control Units : Microprogrammed and Hardwired:control unitabdosaidgkv
The document discusses control units in CPUs. There are two main methods for implementing control units: hardwired and microprogrammed. A hardwired control unit generates control signals through circuitry using logic gates, while a microprogrammed control unit generates control signals by executing a stored microprogram. Overall, hardwired control units are faster but less flexible, while microprogrammed control units are slower but more flexible and modifiable.
This document discusses machine instructions and how programs are executed at the machine level. It covers number systems, data representation, memory addressing, instruction types, instruction execution, and addressing modes. Binary numbers are used in computers and represented as vectors. Negative numbers can be represented using sign-and-magnitude, one's complement, or two's complement methods. Memory is made up of addresses that store bits, bytes, and words of data. Instructions perform operations like data transfer, arithmetic, and program flow control. Programs are executed through sequential instruction fetch and execution, using techniques like looping and conditional branching. Addressing modes specify how operands are accessed in instructions.
The document describes different algorithms for filling polygon and area shapes, including scanline fill, boundary fill, and flood fill algorithms. The scanline fill algorithm works by determining intersections of boundaries with scanlines and filling color between intersections. Boundary fill works by starting from an interior point and recursively "painting" neighboring points until the boundary is reached. Flood fill replaces a specified interior color. Both can be 4-connected or 8-connected. The document also discusses problems that can occur and more efficient span-based approaches.
A datapath is a collection of functional units like ALUs and registers that perform data processing along with a control unit to form the CPU. There are three general steps to datapath design: 1) determine instruction classes, 2) design components for each class, and 3) combine the components. Common datapaths include load/store which uses memory addressing and branch/jump which uses instruction addressing. The ALU performs operations like addition and subtraction. The main control unit identifies instruction fields and controls the datapath. Multiplication can be done with combinational or sequential circuits while division similarly uses subtraction and shifting. Floating point uses separate exponent and mantissa fields.
The document discusses linked lists, which are a linear data structure consisting of nodes connected to each other via pointers. Each node contains data and a pointer to the next node. There are several types of linked lists including singly linked lists where each node has a next pointer, doubly linked lists where each node has next and previous pointers, and circular linked lists where the last node points to the first node. The document covers terminology, advantages and disadvantages, operations, and implementations of different types of linked lists such as dynamic vs static memory allocation and uses in applications.
The document discusses how computers represent data using binary numbers (1s and 0s). It explains that binary is used because it provides an easy way to represent two states (on/off) in storage devices. It then discusses how different numbers of bits (binary digits) can be used to represent different numbers in binary, and provides examples of converting between binary and decimal numbers. Finally, it briefly introduces the concept of data compression for reducing the size of files.
Associative memory, also known as content-addressable memory (CAM), allows data to be searched based on its content rather than its location. It consists of a memory array, argument register (containing the search word), key register (specifying which bits to compare), and match register (indicating matching locations). All comparisons are done in parallel. Associative memory provides faster searching than conventional memory but is more expensive due to the additional comparison circuitry in each cell. It is well-suited for applications requiring very fast searching such as databases and virtual memory address translation.
A register is a group of flip-flops that can each store one bit of information. A processor uses registers to hold instructions, addresses, and data for manipulating information. The document lists several common computer registers - the Data Register stores 16-bit operands from memory, the Address Register holds 12-bit memory addresses, the Accumulator is a general purpose 16-bit processing register, and the Program Counter contains the 12-bit address of the next instruction. Temporary and input/output registers are also used to store intermediate data and user input/output respectively.
This document discusses different approaches to implementing scope rules in programming languages. It begins by defining lexical/static scope and dynamic scope. It then discusses how block structure and nested procedures can be implemented using stacks and access links. Specifically, it describes how storage is allocated for local and non-local variables under lexical and dynamic scope models. The key implementation techniques discussed are stacks, access links, displays, deep access, and shallow access.
The document discusses R-trees, a data structure used to index multi-dimensional spatial data. R-trees allow for efficient searching of spatial data by grouping data into minimum bounding rectangles (MBRs) and storing them in a tree structure based on these envelopes. The tree structure resembles a B+-tree, with internal nodes containing pointers to child nodes or data records. R-trees provide efficient search, insertion, and deletion of spatial data objects through operations on the tree structure and splitting or merging of nodes as needed.
This document discusses randomized algorithms. It begins by listing different categories of algorithms, including randomized algorithms. Randomized algorithms introduce randomness into the algorithm to avoid worst-case behavior and find efficient approximate solutions. Quicksort is presented as an example randomized algorithm, where randomness improves its average runtime from quadratic to linear. The document also discusses the randomized closest pair algorithm and a randomized algorithm for primality testing. Both introduce randomness to improve efficiency compared to deterministic algorithms for the same problems.
Semantic networks are a knowledge representation technique where concepts are represented as nodes in a graph, and relationships between concepts are represented as links between nodes. There are different types of semantic networks, including definitional networks that emphasize subclass relationships, assertional networks for making propositions, and executable networks that can change based on operations. Common semantic relations include IS-A for subclasses, INSTANCE for examples, and HAS-PART for components. While semantic networks provide a natural representation of relationships, they have disadvantages like lack of standard link names and difficulty representing some logical constructs.

It also discusses logic micro operations and shift micro operations, providing examples of each type.
Projection is the transformation of a 3D object into a 2D plane by mapping points from the 3D object to the projection plane. There are two main types of projection: perspective projection and parallel projection. Perspective projection uses lines that converge to a single point, while parallel projection uses parallel lines. Perspective projection includes one-point, two-point, and three-point perspectives. Parallel projection includes orthographic projection, which projects lines perpendicular to the plane, and oblique projection, where lines are parallel but not perpendicular to the plane.
Floating Point Representation premium.pptxshomikishpa
This document discusses floating point representation of numbers in computers. It explains that there are two types of computer arithmetic: integer arithmetic and real arithmetic. Real arithmetic uses numbers with fractional parts and includes fixed point arithmetic and floating point arithmetic. Fixed point arithmetic represents numbers in binary form with a sign bit, integral part, and fractional part. Floating point representation uses scientific notation and normalized notation to represent numbers with a sign bit, mantissa, and exponent. It allows for a much larger range of numbers than fixed point representation.
This document discusses different number systems used in computers such as binary, decimal, octal and hexadecimal. It provides examples of converting between these number systems. The key points are:
- Computers use the binary number system and understand numbers as sequences of 0s and 1s.
- Other common number systems include decimal, octal and hexadecimal, which use different bases.
- Methods for converting between number systems include dividing the number by the new base or using shortcuts that group digits in specific ways.

Computer Representation of Numbers and.pptxTemesgen Geta
- Computers use binary to represent numbers, where each digit is either a 1 or 0. Real numbers are approximated using floating point representation with sign, mantissa, and exponent fields.
- Integers can be stored by reserving bits for the magnitude and using the first bit to indicate sign (sign-magnitude representation) or by using two's complement representation where the most significant bit indicates sign.
- When storing numbers in memory, multiple bytes are typically used to represent integers or floating point values to support a wider range of numbers.
This document discusses different number systems including decimal, binary, octal, and hexadecimal. It explains how to represent numbers in these different bases and how to convert between bases. Key points covered include binary arithmetic operations like addition, subtraction, multiplication, and division. Complement representations for negative numbers like 1's complement and 2's complement are also summarized.
Real numbers include integers, rational numbers like fractions, and irrational numbers like pi. They can be positive, negative, or zero. In computing, real numbers are represented using floating point notation, where the number is stored as a mantissa and exponent. The mantissa holds the significant digits of the number, while the exponent tracks the decimal place. Increasing the bit sizes of the mantissa and exponent allows for greater accuracy or range of real numbers that can be represented, respectively.
The IEEE 754 standard defines the floating point representation of real numbers. It uses a sign-magnitude format that includes:
1) A sign bit to indicate positive or negative.
2) A biased exponent stored with an offset to allow negative exponents.
3) A mantissa or significant digits with a leading 1 not explicitly stored.
For single precision floats, this uses 32 bits broken into an 8-bit exponent and 23-bit mantissa. Doubles use 64 bits with an 11-bit exponent and 52-bit mantissa for greater precision and range.

Adaptive synchronous sliding control for a robot manipulator based on neural ...IJECEIAES
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
2. There are two types of arithmetic
operations :-
Integer Arithmetic
Real – floating point arithmetic
Integer Arithmetic :- deals with
integer operands.
i.e. - num without fractional parts
Real Arithmetic :- use number with
fractional parts as operands and is
use
Real no. = mantissa * 10^exponent
3. COMPUTER
REPRESENTATION OF
FLOATING POINT NUMBERS
In the CPU, a 32-bit floating
point number is represented
using IEEE standard format as
follows:
S | EXPONENT | MANTISSA
where S is one bit, the EXPONENT
is 8 bits, and the MANTISSA is
23 bits.
4. The mantissa
represents the leading
significant bits in the number.
It is made less than 1 and
greater than or equal to 0.1
The exponent
is used to adjust the position
of the binary point (as opposed
to a "decimal" point)
In power of 10 and multiplies
with mantissa
5. Normalization :-
Mantissa and Exponent have
their own independent signs
While storing no. of the
leading digit in the mantissa,
mantissa is always made non-
zero by appropriately shifting
it and adjusting the value of
the exponent
The shifting of mantissa to the left
till its most significant digit is non-
zero is called normalization.
