This document discusses digital systems and their use of discrete signals to represent information. It covers the history of digital systems from early computers using vacuum tubes to today's integrated circuits. The document also describes different types of logic devices including standard logic, custom logic, and programmable logic devices. It provides examples of number systems and conversions between binary, decimal, octal, and hexadecimal numbering systems. Exercises are included for practice converting between these number bases.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. Before the introduction of VLSI technology most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.
The History of the transistor dates to the mid-1920s when several inventors attempted devices that were intended to control current in solid-state diodes and convert them into triodes. Success came after World War II, when the use of silicon and germanium crystals as radar detectors led to improvements in fabrication and theory. Scientists who had worked on radar returned to solid-state device development. With the invention of transistors at Bell Labs in 1947, the field of electronics shifted from vacuum tubes to solid-state devices.
With the small transistor at their hands, electrical engineers of the 1950s saw the possibilities of constructing far more advanced circuits. However, as the complexity of circuits grew, problems arose.
One problem was the size of the circuit. A complex circuit like a computer was dependent on speed. If the components were large, the wires interconnecting them must be long. The electric signals took time to go through the circuit, thus slowing the computer.
The Invention of the integrated circuit by Jack Kilby and Robert Noyce solved this problem by making all the components and the chip out of the same block (monolith) of semiconductor material. The circuits could be made smaller, and the manufacturing process could be automated. This led to the idea of integrating all components on a single silicon wafer, which led to small-scale integration (SSI) in the early 1960s, medium-scale integration (MSI) in the late 1960s, and then large-scale integration (LSI) as well as VLSI in the 1970s and 1980s, with tens of thousands of transistors on a single chip (later hundreds of thousands, then millions, and now billions (109)).
A review of the history of digital design throughout the years until the era of programmable logic, and a detailed exploration of the architecture of FPGA chips, followed by an introduction to SoC FPGAs and some of their benefits.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

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.

1. CPE 301 – DIGIAL SYSTEMS WITH VHDL
• A digital system is a system that takes digital signals as inputs,
processes them, and produces digital output signals. A digital signal is a
signal in which discrete steps are used to represent information and
change values only at discrete (fixed) time intervals.
• In contrast, analog signals have “continuous” variations in signal
amplitude over time. At a given instant of time, an analog signal has
infinite possible values.
• A digital signal has discrete amplitude and time.
Areas of application
• Digital systems are very useful in the areas of signal processing (i.e.,
audio, images, speech, etc.), computing, communication, and data
storage, among others.
2. Brief History of Digital System
• In 1939, Harvard University built the Harvard Mark I, which went into
operation in 1943.
was used to compute ballistic tables for the U.S. Navy.
• 1945 - ENIAC (Electronic Numerical Integrator and Computer)
built component by component at the Moore School of Electrical Engineering at
the University of Pennsylvania.
• 1951 – UNIVAC, first commercially produced computer
• These first-generation computers used vacuum tubes and valves as
primary electronic components
were bulky, expensive, and consumed immense amounts of power
3. Brief History of Digital System
• 1948 – Transistor invented at the Bell Telephone Laboratories by
physicists John Bardeen, Walter Brattain, and William Shockley.
• Transistor revolutionized the way that computers were built.
• Then with the arrival of IC technology, their utility increased
exponentially.
• ICs are inexpensive when produced in large numbers, reliable, and
consume much less power than do vacuum tubes.
• IC technology makes it possible to build complete digital building
blocks into single, minute silicon “chips.”
4. STANDARD LOGIC DEVICES
• Many ICs are available as standard chips.
standard chips because their functionality and configuration meet agreed-upon
standards
• The advantages of using standard chips are their ease of use and ready
availability.
• Generally do not have complex functionality
means that many such chips have to be put together on a PCB
leading to a requirement for more area and components.
• Examples include:
7400 series, such as the
7404 (hex inverters) and 7432 (quad two-input OR gates).
5. CUSTOM-DESIGNED LOGIC DEVICES
• Designed to meet the specific requirements of an application i.e. ASIC
• They are optimized for a specific application
hence perform better than equivalent circuits built from off-the-shelf ICs or
programmable logic devices.
• They occupy very little area (i.e. less PCB area), as all of the logic can be built
into one chip.
Disadvantages
• They are economical only when there is bulk production of the ICs
• It requires the work of highly skilled engineers in the design, manufacturing,
and test stages.
• Design time for the chips very high (lot of verification to check for correct
functionality)
6. PROGRAMMABLE LOGIC DEVICES
• PLDs have a very general structure and contain programmable switches, which
allow the user to configure the internal circuitry to perform the desired function.
• The programmer can configure these switches by writing a program in a hardware
description language (HDL) such as VHDL or Verilog and “downloading” it into the
chip.
• Popular types of PLDs include:
Simple programmable logic devices (SPLDs)
Programmable array logic (PAL)
Programmable logic array (PLA)
Generic array logic (GAL)
Complex programmable logic devices (CPLDs)
FPGA (field-programmable gate arrays)
FPIC (field-programmable interconnect)
7. • Schematic Structure of PALs and PLAs CPLD Internal Structure
FPGA Internal Structure
8. • Different manufacturers of PLDs choose different architectures for
implementing the logic blocks and the programmable interconnection
switch matrices.
• FPGAs have the highest gate count among the various PLDs, which can
accommodate much larger designs than can SPLDs and CPLDs.
• FPGAs have millions of transistors in one chip.
• PALs and PLAs generally carry just a few hundred or a few thousand gates.
• PLD manufacturers include:
Altera Corporation
Xilinx Inc.
LatticeSemiconductor
Cypress Semiconductor
Atmel, Actel, Lucent Technologies, and QuickLogic.
9. Bases and Number Systems
• A number in decimal representation is made of digits that range from 0 to 9.
Consider the following decimal number:
(4261)10 = 4 x 104 x 2 x 102 + 6 x 101 + 1 x 100
• This number is normally written as 4261
• Decimal representations are said to be base-10 or radix-10 numbers because
each digit has 10 possible values, weighted as a power of 10, depending on
the position of the digit in the number.
• Similarly, in binary representation, each binary digit has two possible values,
1 and 0, and the digits are weighted as a power of 2, depending on their
position in the number. The binary system of representation is also known as
a base-2 system.
(1001)2 = 1 x 23 + 0 x 22+0 x 21+ 1 x 20 = (9)10
10. • Numbers in binary form can be rather long, exhausting, and difficult to
remember.
Binary numbers are often represented in more compact forms using the octal (base
8) and hexadecimal (base 16) systems.
Octal system: digits 0 through 7
Hexadecimal system: 0-9 and the letters A-F, where A represents the decimal 10 and F
represents the decimal 15.
17. DATA ORGANIZATION
• A binary number is a sequence of bits that may represent an actual
binary number, a character, or an instruction.
• A group of consecutive 4 bits is called a nibble.
• A nibble is used to represent a BCD or hexadecimal digit.
• A group of consecutive 8 bits is called a byte, which is the smallest
addressable data in memory.
• A byte is also used to represent an alphanumeric character.
• A group of consecutive 16 bits, called a word, can be divided into a high
byte and a low byte.

Editor's Notes
Digital systems are so commonplace in today’s world that we tend to miss seeing them. Almost all electronic systems are partially or totally digitally based. Of course, real-world signals are all analog, and interfacing to the outside world requires conversion of a signal (information) from digital to analog.
A ballistic table or ballistic chart is a tool which predicts the trajectory of a projectile, and is used to compensate for physical effects in order to increase the probability of the projectile reaching the intended target. Ballistic tables are used in hunting, sport shooting, military and scientific applications.
Transistors are used as electrical switches that can be in the “on” or “off” state and so can be used to build digital circuits and systems.
These are referred to as standard chips because their functionality and configuration meet agreed-upon standards.
Chips designed to meet the specific requirements of an application are known as application-specific integrated circuits (ASICs) or custom-designed chips.
Advances in VLSI technology made possible the design of special chips, which can be configured by a user to implement different logic circuits.
Early SPLDs were simple and consisted of an array of AND gates driving an array of OR gates. An AND gate (known as an AND plane or AND array) feeds a set of OR gates (an OR plane). This helps in realizing a function in the sum-of-products form.
The difference btw PALs & PLAs is that in PLA, both the AND & OR planes are programmable, whereas in PALs, the AND plane is programmable but the OR plane is fixed.
PALs & PLAs are useful for small digital circuits which do not require more than 32 inputs and outputs. CPLDs are used to implement circuits with more inputs and outputs.
FPGAs differ from the other PLDs and generally offer the highest logic capacity. An FPGA consists of an array of complex logic blocks (CLBs) surrounded by programmable I/O blocks (IOBs) and connected by a programmable interconnection network.
Binary systems is a fundamental feature of modern digital electronic devices.
A conversion is carried out by first dividing the given decimal number by 2. The quotient that results from each division step is again divided by 2 and the remainders are noted in each step. The remainders form the actual binary number.
The conversion of a binary number to an octal number or a hexadecimal number requires converting the binary digits in groups of 3 or 4, respectively, starting from the least significant bit.
Once the binary number is formed, it can be converted into any of the other representation systems using the procedures above.
In general, the size of the microcomputer internal registers determines the size of binary grouping. A 16-bit microcomputer has two bytes, or a 16-bit word size. However, the memory unit is divided into an 8-bit, or byte, word length. For example, to store a 16-bit number, the microcomputer uses two consecutive byte locations in the memory space.
