This document discusses considerations for reusing components in automotive systems designed according to ISO 26262 functional safety standards. It begins with an overview of ISO 26262 and its requirements for reusable components called Safety Elements Out of Context (SEooCs). Suppliers often deliver SEooCs to customers, with documentation like a safety manual describing proper deployment. For non-SEooC components, a Development Interface Agreement is required. While ISO 26262 does not directly address open source software, some argue it could be qualified for safety-critical use if specified, tested, and documented rigorously. In general, component reuse aims to increase quality and efficiency if managed carefully according to ISO 26262 processes.

Tara K. Thimmanaik, Solutions Architect at Intel, presents the “Smarter Manufacturing with Intel’s Deep Learning-Based Machine Vision” tutorial at the September 2020 Embedded Vision Summit.
As demand for smarter and more efficient manufacturing is growing, IoT technologies—including sensors, edge devices, gateways, servers and the cloud—are being used throughout the factory to compute deep learning analytics workloads at the appropriate location. Efficient data-driven manufacturing can help to reduce labor costs, increase quality and maximize profit. The biggest hindrance to achieving these outcomes is the difficulty in extracting data from vendor-locked and proprietary systems for analytics downstream.
In this presentation, Thimmanaik covers Intel’s approach to developing open, flexible and scalable solutions, including:
• Intel’s technologies such as OpenVINO, Movidius Vision Processor Units, Edge Insights Software (EIS) and deep learning algorithms
• How Intel’s offerings come together in the industrial marketplace with partnerships forged to address the constraints of manufacturing infrastructure
• Real-world examples highlighting defect detection in textile printing (where 90% accuracy at 50 fps was achieved) and smartphone screen production (where false negatives were only 0.6%)

The document compares the properties of linear and SMPS power supplies. Linear power supplies are large, heavy, and have low operating costs but produce low noise. SMPS power supplies are smaller, lighter, and have higher operating costs but produce more noise. The document then describes the components and operation of a typical SMPS circuit, including the rectifier, filter capacitors, switching transistor, driver circuitry, transformers, rectifier diodes, and output filter components. It notes that a driver circuit is needed between the PWM IC and switching transistor due to the low output of the PWM IC.
This document discusses different types of CD disks including audio CDs, CD-ROMs, CD-Rs, and CD-RWs. It describes their uses and capabilities. Audio CDs can store up to 74 minutes of music. CD-ROMs can store data, databases, and other files but cannot be rewritten. CD-Rs can only be written once but are useful for backups. CD-RWs can be erased and rewritten, allowing data to be transferred between systems. The document also provides technical details about CD layer structures and how CD drives work.
The document discusses memory technologies and the memory hierarchy. It describes RAM technologies like SRAM and DRAM, how DRAM is organized into rows and columns, and how enhanced DRAM technologies provide faster access. It also discusses non-volatile memories like ROM, disk storage technologies including geometry, capacity calculations, and access times that are thousands of times slower than RAM.
The document discusses key aspects of the IEEE 802.11 wireless networking standard, including:
- The 802.11 standard aims to specify wireless connectivity for fixed, portable, and mobile devices within a local area.
- It includes amendments for various physical layer specifications and frequencies, as well as security improvements.
- The standard supports both infrastructure and ad-hoc network models using technologies like Wi-Fi, and defines frame formats and media access control procedures.
Computers can be classified into four main categories based on their processing power and size: micro computers which use a microprocessor as the CPU, mini computers which are larger than micros but smaller than mainframes, mainframe computers which are the largest and most powerful, and super computers which are the fastest and most advanced systems currently available for processing large amounts of data and performing complex calculations.
The OSI model defines 7 layers of standards for networking and operating systems involved in networking functions. The 7 layers are: application, presentation, session, transport, network, data link, and physical. Each layer has a specific role, with the highest layers dealing with application and user issues and lower layers dealing with physical network connections and transmission of raw data.
This document describes the architecture and instruction set of a custom digital signal processor (DSP). The DSP contains a signal processing controller (SPC) that fetches and executes instructions. It has two multiplier-accumulator-RAM (MAR) units - one for real parts and one for imaginary parts - to perform complex arithmetic operations on digital signals. The SPC uses registers to address locations in the MARs and store complex numbers by separating the real and imaginary parts. Assembly code examples show how instructions implement operations like complex multiplication by manipulating data in the MARs.
The document is a slide presentation that provides an introduction to the Domain Name System (DNS). It discusses key concepts such as:
- DNS provides a mapping between domain names that are easy for humans to remember (e.g. www.example.com) and IP addresses that computers use to locate services.
- The DNS database is distributed across multiple name servers around the world to provide reliability and scalability. Changes propagate according to timing parameters.
- Name servers include authoritative servers that store official data for a zone, and recursive servers that handle lookups on behalf of clients and cache results.
- The domain name space is hierarchical with delegation of subdomains, and zones define administrative boundaries for domain data.
Ethernet is a widely used shared access network technology where multiple nodes share the same physical link. It uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) as its media access control protocol. When a node has a packet to transmit, it first listens to ensure the link is idle before transmitting. If a collision is detected during transmission, the node stops transmitting and performs exponential backoff before retransmitting. This helps ensure fair access among nodes. Fast Ethernet and Gigabit Ethernet were later developed to provide higher bandwidths up to 1Gbps while maintaining compatibility with Ethernet's CSMA/CD protocol.
This document discusses a Yahoo zero-day vulnerability from a code point of view. It covers bug bounty programs, remote code execution vulnerabilities like those using eval(), and provides a live example tool called WebPwn3r and demo videos. The document is authored by Ebrahim Hegazy, a cyber security analyst at Q-CERT, and is published on April 12, 2014 by the OWASP Foundation under an open license.
Cisco Packet Tracer is a network simulation software that allows users to design, configure, and test networks virtually. It provides benefits for both instructors and students by making networking concepts more visual and hands-on. Key features include simulating network devices and protocols, visualizing network traffic, authoring activities, and enabling multi-user collaboration. Packet Tracer supports Cisco Networking Academy curricula and the latest version adds enhancements like improved wireless security and VOIP support.
