Introduction to Embedded Systems
This presentation gives a brief over view of Embedded Systems. It describes the common characteristics of Embedded systems, the design metrics, processor technologies and also summarizes differences between Microcontrollers and Microprocessors.
Introduction to Embedded Systems
An embedded system is a dedicated computer system that performs specific tasks, and is embedded as part of a complete device including hardware and software. Examples include watches, washing machines, cell phones and more. Embedded systems have limited memory and processing capabilities compared to general purpose computers. They also have dedicated functions and real-time constraints. Microcontrollers are commonly used in embedded systems and contain a CPU, memory and programmable input/output peripherals on a single chip. Real-time operating systems help schedule tasks to meet timing constraints in embedded systems.
Computer Interfaces
USB (Universal Serial Bus) is a standard interface that allows devices to be connected using a single standardized port. It replaced multiple previous standards with a single connection type. RS-232 is an older serial communication standard that defines the signals and connectors used between data terminal equipment and data communication equipment for asynchronous transmission of data. Firewire (IEEE 1394) is a serial bus interface standard that allows for high-speed communications and has features like hot pluggability and power delivery through the cable. It has higher maximum speeds than USB but shorter cable lengths.
An Entire Concept of Embedded systems
This document provides an overview of embedded systems topics including:
1. It outlines an agenda to cover embedded system basics, processors and architectures, serial communication, real-time operating systems, and embedded programming demos.
2. It defines embedded systems as systems with dedicated software embedded in hardware to perform specific tasks as part of a larger system.
3. It discusses different processor types including microprocessors, microcontrollers, digital signal processors, and application specific integrated processors.
Embedded system Design
An embedded system is a computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. Embedded systems are found in many devices such as mobile phones, cars, appliances, and toys [Paragraph 1]. They are typically specialized for their dedicated functions and have constraints on power, size, and cost. Examples of embedded systems include anti-lock braking systems, digital cameras, medical devices, and factory controllers [Paragraph 2]. A key characteristic of embedded systems is that they interact continuously with their environment through sensors and actuators to perform their dedicated functions in real-time [Paragraph 3].
Interrupts
The document discusses interrupts in microcontrollers. It defines interrupts as a way to asynchronously process events outside the main program flow. When an interrupt occurs, the microcontroller finishes its current instruction, saves context to the stack, and jumps to the interrupt service routine (ISR) before returning to the main program. The document outlines the interrupt sequence and describes how to define an ISR. It also discusses interrupt priorities, nesting, and the registers used to configure and manage interrupts.

Embedded
An embedded system is a dedicated computer system that performs specific tasks. An important application of embedded systems is anti-lock braking systems (ABS) in automobiles. ABS uses sensors and electronic control modules to monitor wheel speed and automatically modulate brake pressure to prevent wheel lockup and maintain steering control during emergency braking. By preventing skidding, ABS can help drivers stop more safely and shorten stopping distances on wet or slippery surfaces compared to standard brakes. ABS works by pulsing the brakes rapidly when it detects a wheel is about to lock up, which allows the wheel to continue turning and maintaining traction with the road.

Microprocessors and microcontrollers
A microprocessor and microcontroller are the central components of embedded systems. Due to their small size, low cost, and simple design, embedded systems have become ubiquitous in both consumer and industrial devices (paragraph 1). Embedded systems can be found in applications like biomedical devices, communication systems, computer peripherals, industrial instrumentation, scientific equipment, and more (paragraphs 2-3). Earlier embedded systems used microprocessors which required external components, but modern systems typically use microcontrollers which integrate memory and I/O peripherals onto a single chip for a simpler design (paragraphs 4-6). A microcontroller contains components like an ALU, memory, I/O ports, timers/counters, and more, making it well-suited

Keypad Based Bank Locker Security System Using Gsm Technology
Banking is one of the sectors where technology and advancements in technologies have not been utilized to the fullest potential. In the security systems even today very old practices are followed that can be made lot better using technologies like GSM which is easily usable and also easy to implement at a consumer level. In this project we propose a GSM based secure access which can provide a sophisticated theft alert system for bank locker system. This system contains microcontroller, keypad, GSM module and LCD display. By using keypad we need to enter the password that is provided to the authenticated persons. If the password entered is wrong then the GSM network converts the digital information into airborne signals and SMS is transferred to the registered mobile number. This system offers better solution for the bank security system and it will also help us to track the person who tried to open the locker without the permission and proper authentication.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
