Single board computers (SBCs) contain all the necessary components of a computer, such as the microprocessor, storage, memory, and I/O, on a single circuit board. SBCs are commonly used for embedded applications in devices like ATMs, medical equipment, and industrial computers. They have evolved over time from selections based primarily on the CPU to considerations of software, size, and time-to-market. SBCs can reduce development time and rely on proven designs, though may not be suitable if special configurations are needed. Implementation of SBCs involves programming like operating systems, communication, and control using languages like C. They can be assembled into clusters like a Raspberry Pi-based Beowulf

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
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.
3. What is a Single Board Computer?
A single board computer, or SBC, is a type of computer
where all of the computer components are built onto a
single circuit board.
Desktop computers and laptops usually have separate
components that are connected by cables to a central
circuit board.
A single board computer contains the
microprocessor, storage and memory,
as well as other necessary components,
in a single circuit board.
3 Prof.Anish Goel
4. Types of Single Board Computers
There are several different kinds of single board
computers.
Many of the most common
types are categorized by CPU
Manufacturer, Processor
Speed and Packaging Type.
4 Prof.Anish Goel
5. Applications for Single Board Computers:
Single board computers are found embedded in larger
devices including:
ATM machines
Industrial computers
Medical equipment
Automation equipment
Cash registers
Touch screen kiosks
5 Prof.Anish Goel
6. Evolution
Single Board Computers (SBCs)
have changed dramatically over
the years.
Initially the selection factor was
based primarily on the CPU and
its associated peripheral chips.
Twenty years ago that meant Intel, Zilog, or Motorola were the
silicon vendors for microprocessor systems.
As the density, complexity and capability of the silicon
improved, so did the choice and selection methodology for
SBCs.
Today software, board size, and time-to-market are the key
decision factors in addition to just the power and speed of the
CPU.
6 Prof.Anish Goel
7. When to use an SBC.
Reduces development time for faster Time-to-Market
Proven design by vendor increases reliability and reduces risk
Multiple vendors provide a variety of different size, functions,
and price options
Component-level design is
too complex for in-house
engineers
Lack of internal company
resources
Lack of internal manufacturing
expertise
7 Prof.Anish Goel
8. When not to use an SBC.
Not cost effective for very large volumes
Application requires a special size or format
A special CPU or configuration is needed for the
application
Non-commercial environment because of shock,
vibration, heat, humidity, radiation, or power requirements
Special I/O interface needs
8 Prof.Anish Goel
9. Underlying Technology behind Single Board
Computers
Main features of single board computers include a single or
dual microprocessor, RAM, IO, and any other features to
complete a computer on one board.
As the technology of SBCs increased,
the demand for PC compatibility in
embedded applications increased.
The current primary use for SBCs is
for embedded technology.
One aspect of embedded technology is the capability to
perform dedicated functions in an embedded environment.
An embedded environment refers to a part of a complete
device including hardware and mechanical parts.
One common environment used with single boards is for
network adapters.
9 Prof.Anish Goel
10. Technology
Network adapters provide an interface between a computer
and the physical medium comprising the network connection;
they usually consist of a single board. Network interfaces
support one or more communications protocols, which specify
how the computers use the physical medium to exchange data.
Regardless of the environment, a SBC will usually have the
appropriate tools necessary for any embedded system.
10 Prof.Anish Goel
11. Implementation of Single Board Computers
for Embedded Systems
Implementing software onto single board computers has become increasingly
simple as the technology now supports linux on the SBCs.
Software for different systems will do different things.An example of how software
is implemented on SBCs was found in an article about implementing a SBC for
robot control.
In this scenario, the software consisted of an operating system, communication with
the host computer, and an interrupt driven control part.
All programming was done in the C language.
For the majority of embedded systems, programming in the C language is all that
will be necessary to control the device with the single board computer.
11 Prof.Anish Goel
12. Implementation
As the complexity of embedded systems grows, higher
level tools and operating systems are migrating into
machinery where it makes sense.
The result is that any
programming language can
be used on a single board
computer granted the
software on the board
will support it.
12 Prof.Anish Goel
13. Raspberry Pi-Based Beowulf Cluster
a Beowulf cluster is simply a collection of identical,
(typically) commodity computer hardware based systems,
networked together and running some kind of parallel
processing software that allows each node in the cluster
to share data and computation.
Typically, the parallel programming software is MPI
(Message Passing Interface), which utilizes TCP/IP along
with some libraries to allow programmers to create
parallel programs that can split a task into parts suitable
to run on multiple machines simultaneously.
13 Prof.Anish Goel
14. Building the System
There are really only five major components needed for a
working cluster: computer hardware, Linux OS, an MPI
library, an ethernet switch, and possibly a router.
RPi is the computer hardware. Figure shows the overall
network architecture.
The system design includes 32 RPi nodes, 48-port 10/100
switch,Arch Linux ARM, and MPICH3.
