In addition, patterns create a common method to communicate, document and describe solutions. This session will explain some of these patterns ranging from SOA (Service-Oriented Architecture), WOA (Web-Oriented Architecture), EDA (Event Driven Architecture), and IoT (Internet of Things)
Accelerating Digital Transformation: It's About Digital Enablement
Digital Transformation is a strategy that industries have been embracing over the past several years. Efforts are maturing but organizations are continuing to struggle to capture new digital value and reflect it on the bottom line. Digital Transformation efforts for most legacy companies are struggling, as they are looked on as a Technology problem.
Any "Transformational" strategy must address all the stakeholders involved as well as have a focus on delivering value to these stakeholders at multiple levels. Success can and has been delivered through the creation of Digital Transformation Enablement Programs that address the multiple stakeholder dimensions (people, process, and technology) and ultimately lead to digital being just how we do business.
In this discussion I will specifically outline the steps that we have leveraged to deliver Digital Transformation Enablement and as a byproduct change the way people work, how they approach problems with the application of technologies, and ultimately drive new value for their organization and customers.

3. Virtual Memory.pptx
The document discusses different approaches to virtual memory including overlays, paging, and segmentation. Paging maps program addresses to RAM addresses through indirection to allow programs to access more memory than physically available. Segmentation divides RAM into segments allocated to each program to isolate programs and improve security while still allowing an illusion of unlimited memory through virtual addressing.
2. Cache Mapping.pptx
This document discusses different cache mapping techniques including direct mapping, associative mapping, and set-associative mapping. It provides examples of direct mapping where the main memory is divided into pages that map to cache frames. Direct mapping allows only one main memory page to map to each cache frame based on the page number. Associative mapping allows any main memory page to map to any cache frame by using a content addressable memory. Set-associative mapping groups cache frames into sets, and each main memory page can map to one of the frames within a set. The document also gives an example of how cache hit rates can be different between direct mapping, 2-way set associative mapping, and fully associative mapping.

1. Introduction to Memory.pptx
The document discusses memory and input/output organization in computer architecture. It covers topics like memory hierarchy, cache memory, virtual memory, parallel and serial bus architectures, and input/output devices. Specifically, it describes the memory hierarchy from fastest to slowest as CPU cache, RAM, and hard disk drive. It also explains the different levels of CPU cache memory (L1, L2, L3) and how they improve processing speed.
6. ILP.pptx
1) Instruction level parallelism (ILP) refers to executing multiple instructions simultaneously by exploiting parallelism between independent instructions.
2) Methods to increase ILP include increasing the pipeline depth, replicating pipeline components to launch multiple instructions per stage, and using multiple issue to dispatch two or more instructions per cycle.
3) Static multiple issue uses the compiler to package instructions into issue packets for simultaneous issue, while dynamic multiple issue relies on hardware to dynamically schedule instructions during execution to overcome hazards and dependencies.
5. Exception.pptx
An exception is an unexpected event that occurs internally in the processor and disrupts program execution, while an interrupt is an external event that causes an exception. There are three types of exceptions: arithmetic overflow, undefined instruction, and system call. When an exception occurs, the processor saves the program counter, sets the cause register, disables further exceptions, and jumps to an exception handler. To return, the handler restores the program counter and reenables exceptions. Multiple exceptions can be handled with polled or vectored interrupts.
4. Pipeline Hazards.pptx
The document discusses different types of pipeline hazards including structural hazards, data hazards, and control hazards. It describes data hazards that occur due to dependencies between instructions as read after write, write after read, and write after write hazards. Methods to overcome data hazards include forwarding, stalling, and reordering instructions. Control hazards occur due to branches, and can be addressed through stalling, prediction, or delayed branching. Dynamic branch prediction uses 1-bit or 2-bit prediction schemes stored in a branch history table to more accurately predict branches.
3. Implementation of Pipelining in Datapath.pptx
The document discusses pipelining in CPU instruction execution. It describes the typical 5 stages of instruction execution: fetch, decode, execute, memory access, and write back. It shows how pipelining allows overlapping execution of multiple instructions across the stages, improving instruction throughput compared to single-cycle execution where each instruction must complete all stages before the next begins. Pipelining is implemented by dividing the CPU datapath into independent stages that each complete a part of the instruction execution process in parallel.
2. Datapath Design with Control Unit.pptx
The document discusses the data path and control unit for different types of instructions in a CPU. It describes three main types of instructions - memory reference using load and store instructions like lw and sw, arithmetic/logical instructions like add and sub, and branch instructions like beq. It then provides examples of each type of instruction and illustrates the simple data path used to process R-type, load/store, and branch instructions respectively.
1. Introduction to Datapath Design.pptx
The document discusses the processor unit and its components. It describes the different types of instructions like memory reference, arithmetic logical, and branch/jump. The key components of a datapath include a program counter, instruction memory, adder, register file, ALU, data memory, and multiplexers. Memory reference instructions use the adder, arithmetic instructions use the ALU, and branch instructions use a subtractor to evaluate the branch condition. A branch datapath also includes a separate adder to compute the branch target.
Floating Point Multiplication.pptx
The document describes the floating point multiplication algorithm in 5 steps:
1) Convert the numbers to normalized binary representation.
2) Add the exponents.
3) Multiply the significant bits.
4) Normalize the product and round the significant bits if needed.
5) Set the sign of the product.
It then provides an example of multiplying 0.5 and -0.4375 in binary using this algorithm.
Floating Point Addition.pptx
This document describes the floating point addition algorithm and provides two examples of performing floating point addition in binary. The algorithm involves 4 steps: 1) Convert the numbers to normalized binary, 2) Compare the exponents and match the larger one, 3) Add the significant bits, and 4) Normalize and round the sum if needed. The examples show applying this algorithm to add 0.5 and 0.4375, yielding 0.9375, and to add 10.01101 x 21 and 0.00101101 x 22, yielding 1.01100001 x 22.
Floating Point Represenataion.pptx
The document discusses binary floating point representation in IEEE 754 format. It explains the components of a floating point number, including the sign bit, mantissa/fraction, and exponent. It provides examples of single and double precision representations. Finally, it briefly introduces the IEEE 754 half precision format which uses 16 bits with a 5 bit exponent and 10 bit mantissa.
Refined Version of Division.pptx
This document describes an improved version of the division algorithm for unsigned binary division. It presents the steps to divide 7 by 3 as an example, showing the divisor, remainder, and operations at each step. The improved algorithm shifts and restores the remainder at each step rather than just subtracting the divisor. In the end, it correctly calculates a quotient of 2 and remainder of 1, matching 7 divided by 3.
Version 1 Division.pptx
The document describes version 1 of a binary division algorithm. It provides an example of using the algorithm to calculate the quotient and remainder of 7 divided by 3 in binary. The algorithm works by repeatedly subtracting the divisor from the remainder, shifting the quotient left by 1 bit and shifting the divisor right by 1 bit until the remainder is smaller than the divisor. For the example calculation, the quotient is calculated to be 2 and the remainder is 1.
BOOTH’s ALGORITHM Part 1.pptx
Booth's algorithm is a method for multiplying two binary numbers, including positive and negative numbers, by recoding the multiplier into {-1, 0, +1} and then multiplying the multiplicand by the recoded bits. For example, to multiply the positive numbers +13 and +7 in binary, the document shows recoding +7 as 0+1-1, multiplying +13 by each recoded bit, and adding the results to get the product of 91. The algorithm was created by Andrew Booth to speed up multiplication on early calculators.
2. Addition and Subtraction.pptx
The document discusses addition and subtraction operations in MIPS and overflow. It provides examples of addition and subtraction for both unsigned and signed integers. For unsigned integers, overflow occurs when the result is larger than the maximum value that can be represented. For signed integers in sign-magnitude format, overflow occurs when subtraction results in a number outside the range of the available bits. The document contains examples of calculations and determines whether overflow, underflow, or neither occurs.
1. Introduction to Arithmetic.pptx
The document discusses different numeric representation formats including fixed point, floating point, signed magnitude, one's complement, and two's complement. It provides examples of how fixed point and floating point numbers are represented and describes the process for converting positive and negative numbers to their one's and two's complement representations. Two's complement representation allows positive and negative numbers to be treated together and uses a single representation for zero.
6.Performance.pptx
This document discusses performance metrics for computing systems including response time, throughput, relative performance, CPU execution time, CPU time, and power dissipation. It defines CPU time as the sum of user CPU time and system CPU time. It also provides an equation for dynamic power dissipation that is proportional to the capacitance, voltage squared, and frequency of a computing system.
5. Addressing Modes.pptx
The document discusses different addressing modes in MIPS architecture including immediate, register, base/displacement, PC-relative, and pseudo direct addressing modes. It provides examples of instructions that use each addressing mode and describes how the effective address is calculated for each mode. The document also includes an example MIPS program and its hexadecimal object code.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
