Register transfer language (RTL) represents the transfer of data between registers using symbols. Key components like the ALU, registers, and buses are explained in terms of their role in processing and transferring data and instructions.
Real Time Operating system (RTOS) - Embedded systems
A real-time operating system (RTOS) is an operating system designed for embedded systems where responses need to occur within strict time constraints. An RTOS prioritizes tasks and responds immediately to inputs. There are two types - hard RTOS which must meet deadlines to avoid catastrophic failure, and soft RTOS where occasionally missing deadlines does not cause failure. An RTOS manages tasks, schedules tasks and system resources, and handles interrupts to ensure time-critical applications perform as required.
Introduction to Firmware
From Intrepid's Thursday lecture series, our developer Ryan Meador explains the basics of firmware. Includes firmware background, what's different between a mobile device and a firmware device, underlying technology, & tools and techniques.
Processors and its Types
The document discusses different types of processors including budget, mainstream, dual core, and Intel Pentium and Core 2 processors. It provides details on the architecture and features of Pentium, dual core, and Core 2 processors. Pentium was introduced in 1993 and was a breakthrough as it had 3.1 million transistors. Dual core processors have two separate cores on the same die to allow parallel processing. Core 2 processors were introduced in 2006 and improved on previous designs with dual or quad cores, larger caches, virtualization support, and 64-bit capabilities.
Real time Operating System
This document discusses real-time operating systems (RTOS). It defines RTOS as operating systems that are able to respond to inputs immediately within a specified time delay. It compares RTOS to general operating systems and discusses the types, characteristics, functions, and applications of RTOS. Examples of RTOS like VxWorks are provided. The key functions of an RTOS include task management, scheduling, resource allocation, and interrupt handling. RTOS are widely used in applications that require deterministic responses like avionics, medical devices, industrial automation, and more.
ARM Architecture
- ARM was developed in 1983 by Acorn Computers with a 4-man team to replace the 6502 processor in BBC computers. It has since become one of the most widely used processor cores in the world due to its simplicity, low power consumption, and use in portable devices.
- ARM Holdings licenses the ARM processor core designs to manufacturers but does not manufacture the chips itself. ARM cores power many products including PDAs, phones, media players, handheld game consoles, digital cameras, and more. Popular ARM architectures include ARM7TDMI and ARM9TDMI.
- The ARM architecture uses a load/store design with 32-bit fixed-length instructions operating on a large number of general purpose
Embedded system
This document provides an overview of embedded systems and their processors. It defines an embedded system as having computer hardware and software embedded as important components. Processors are the heart of embedded systems and can be microprocessors or microcontrollers. Components include hardware, memories, ports and application software. Languages for programming embedded systems include C and C++. Embedded systems are classified based on scale, connectivity and mobility. They have constraints like limited memory and need for low power. Common applications include household appliances, audio players, vehicle controllers and medical equipment.
Embedded Systems
An embedded system is a combination of hardware and software that performs a dedicated function within a larger mechanical or electrical system. Embedded systems are designed to respond to events in real-time and operate with limited resources. They are used across many industries in applications like automotive systems, industrial controls, medical devices, office equipment, and more.
Multithreading
The document discusses multithreading and how it can be used to exploit thread-level parallelism (TLP) in processors designed for instruction-level parallelism (ILP). There are two main approaches for multithreading - fine-grained and coarse-grained. Fine-grained switches threads every instruction while coarse-grained switches on long stalls. Simultaneous multithreading (SMT) allows a processor to issue instructions from multiple threads in the same cycle by treating instructions from different threads as independent. This converts TLP into additional ILP to better utilize the resources of superscalar and multicore processors.

Internet of Things (IoT) refers to physical and virtual objects that have unique identities and are connected to the internet to facilitate intelligent applications that make energy, logistics, industrial control, retail, agriculture and many other domains "smarter". Internet of Things is a new revolution of the Internet that is rapidly gathering momentum driven by the advancements in sensor networks, mobile devices, wireless communications, networking and cloud technologies. Experts forecast that by the year 2020 there will be a total of 50 billion devices/things connected to the internet.
This book is written as a textbook on Internet of Things for educational programs at colleges and universities, and also for IoT vendors and service providers who may be interested in offering a broader perspective of Internet of Things to accompany their own customer and developer training programs. The typical reader is expected to have completed a couple of courses in programming using traditional high-level languages at the college-level, and is either a senior or a beginning graduate student in one of the science, technology, engineering or mathematics (STEM) fields. Like our companion book on Cloud Computing, we have tried to write a comprehensive book that transfers knowledge through an immersive "hands on" approach, where the reader is provided the necessary guidance and knowledge to develop working code for real-world IoT applications.
Software engineering lecture notes
The document discusses different software engineering process models including:
1. The waterfall model which is a linear sequential model where each phase must be completed before moving to the next.
2. Prototyping models which allow requirements to be refined through building prototypes.
3. RAD (Rapid Application Development) which emphasizes short development cycles through reuse and code generation.
4. Incremental models which deliver functionality in increments with early increments focusing on high priority requirements.
5. The spiral model which has multiple iterations of planning, risk analysis, engineering and evaluation phases.
RTOS - Real Time Operating Systems
This presentation talks about Real Time Operating Systems (RTOS). Starting with fundamental concepts of OS, this presentation deep dives into Embedded, Real Time and related aspects of an OS. Appropriate examples are referred with Linux as a case-study. Ideal for a beginner to build understanding about RTOS.
Multiprocessor
This document discusses multiprocessor computer systems. It begins by defining a multiprocessor system as having two or more CPUs connected to a shared memory and I/O devices. Multiprocessors are classified as MIMD systems. They provide benefits like improved performance over single CPU systems for tasks like multi-user/multi-tasking applications. Multiprocessors are further classified as tightly-coupled or loosely-coupled based on shared vs distributed memory. Common interconnection structures discussed include bus, multport memory, crossbar switch, and hypercube networks.
Software Engineering Layered Technology Software Process Framework
Software engineering is the application of engineering principles to software development to obtain economical and quality software. It is a layered technology with a focus on quality. The foundation is the software process, which provides a framework of activities. This includes common activities like communication, modeling, planning, construction, and deployment. Additional umbrella activities support the process, such as quality assurance, configuration management, and risk management.
IOT and Characteristics of IOT
The Internet of Things (IoT) is a network of physical objects embedded with electronics, software, and sensors that allows objects to connect and exchange data over the internet. IoT creates opportunities to remotely sense and control objects across networks, improving efficiency. Things in IoT include devices like heart monitors, farm animal tags, sensors in cars, and environmental sensors. These devices collect data using technologies and autonomously share it. IoT requires connectivity between things, intelligence to interpret sensor data, and scalability to handle increased connections.
Embedded Systems - Training ppt
A presentation of summer training done on Embedded Systems. It outlines the basic understanding of embedded systems.
RISC and CISC Processors
CISC processors have a large number of complex instructions that can perform operations directly from memory to memory. In contrast, RISC processors have a small set of simple instructions that operate only within registers, with load and store as separate instructions. The first RISC projects in the late 1970s-early 1980s from IBM, Stanford, and UC-Berkeley aimed for single-cycle execution with a fixed-length instruction format. RISC emphasizes hardware simplicity while CISC focuses on smaller code size and higher cycles per second.

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).

Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Embedded Systems: Lecture 2: Introduction to Embedded Systems
- 1. Linux For Embedded Systems ForArabs Ahmed ElArabawy Cairo University Computer Eng. Dept. CMP445-Embedded Systems
- 2. Lecture 2: Introduction to Embedded Systems
- 3. What is an Embedded System ? • An embedded system is a computer system embedded in a device with a dedicated function • This is different from the traditional, general purpose computer systems
- 4. EXAMPLES OF EMBEDDED SYSTEMS
- 5. Phones and Tablets • Communication Processor (s) • Wifi • GSM/3G/LTE • Bluetooth/NFC • Graphics Processor (s) • Graphics and Video Processing • Application Processor • Android / Windows / iOS
- 6. Robotics
- 7. AUTOMOTIVE
- 8. Cars Are Getting Smarter… • Electronics represents 40% of total cost of a car • 90% of new car features require software
- 10. Automotive
- 11. Military
- 13. Medical Devices
- 16. So Why is it different from Desktop Development • Embedded Systems normally come with constraints in hardware resources • Processing • Memory • Storage • Power • Display • Input/Output devices • Also, embedded system applications often comes with real time system constraints • Latency • Throughput • The system has a strong association between the HW and SW
- 17. OK ….. So What ?? • The developer has to deal with all of these constraints • Development should take into consideration, code efficiency, and code foot print • Debugging tools are “closer to the metal” • Special attention to power consumption in some cases
- 19. Cross-Platform Development • Development Environment is different from target environment • Need for cross platform development and debugging tools
- 20. Embedded Systems Classification • There are two main families of embedded system platforms: • Microcontroller Family • Microprocessor Family
- 21. Embedded Systems Classification Microcontrollers • Examples: PIC (MicroChip), AVR (Atmel), … • Used for example in Arduino Boards • Originally 8/16 bit but recently there are 32 bit chips • Simple instruction set • No or simple OS Support • Limited performance (clock speed up to 10s MHz) • Programming in assembly, or C • Useful in small systems with lower Cost • Typical usage: • Interfacing to sensors • Control of motors in simple robotics systems • Simple home automation • etc…
- 22. Embedded Systems Classification Microprocessors • Examples: ARM, Intel ATOM, MIPS • Used for example in Raspberry Pi, BeagleBone Black, … • 32 bit (and sometimes 64 bits) • Support Linux and other RTOSs • Higher performance (clock speed in 100s MHz to few GHz) • Programming in C/C++ (sometimes with little assembly), Java, Python, … • Strong library support (act as a small computer) • Useful in more complicated systems but with higher cost • Typical Usage: • All what the microcontroller can do • Sophisticated control systems • Audio Processing • Image Processing • Video Processing • Communication Systems • Advanced guidance and navigation systems
- 23. In this course • We will address microprocessor based systems • We will be working with the Raspberry Pi board which uses an ARM • Why, • Because we will be able to do everything the microcontroller can do • On top of that, we will be able to do more advanced projects • We will be able to build projects beyond reading sensors and simple control • We will be able to run with Linux, and make use of all of its available tools and libraries • We will be prepared to understand sophisticated products in the industry
