Jeremy Bennett
●3 comments

This paper introduces the huge range of free and open source software available to the embedded software developer. Hardware modeling, software tool chains, operating systems (RTOS and Linux), middleware and applications are all covered. Today open source is spreading to the hardware world. The paper addresses the advantages and risks associated with using free and open source software, including the issues of quality, support and licensing.

Demystifying digital signal processing (DSP) programming: The ease in realizing implementations with TI DSPs

Texas Instruments

Introduced by Texas Instruments over thirty years ago, the digital signal processor (DSP) has evolved in its implementation from a standalone processor to a multicore processing element and has continued to extend in its range of applications. The breadth of software development tools for the DSP has also expanded to accommodate diverse sets of programmers. From small, low power, yet “smart” devices with applications such as voice and image recognition, to multicore, high-performance compute platforms performing real-time data analytics, the opportunities to achieve the low-power processing efficiencies of DSPs are nearly endless. The TI DSP has benefited from a relatively unique tool suite evolution making it easy and effective for the general programmer and the signal processing expert alike to quickly develop their application code. This paper addresses how TI DSP users are able to achieve the high performance afforded by the TI DSP architecture, in an efficient, easy-to-use development environment.

Arduino Microcontroller Guide

The Arduino microcontroller is an easy to use yet powerful single board computer that has gained considerable traction in the hobby and professional market. The Arduino is open-source, which means hardware is reasonably priced and development software is free. This guide is for students in ME 2011, or students anywhere who are confronting the Arduino for the first time. For advanced Arduino users, prowl the web; there are lots of resources.

The purpose of this book is to get you started on the road to creating things using micro-controllers. We will discuss only enough electronics for you to make the circuits, and only enough programming for you to get started. The focus will be on your making things. It is my hope that as you go through this book you will be flooded with ideas of things that you can make.

New Life for Embedded Systems in the Internet of Things

Wind River

The Internet of Things (IoT) is no longer a fanciful vision. It is very much with us, in everything from factory automation to on-demand entertainment. Yet by most accounts, the full potential of interconnected systems and intelligent devices for changing the way we work and live has barely been tapped. Up until now, IoT software solutions have largely had to be built from scratch with a high degree of customization to specific requirements, which has driven up the cost and complexity of development and deterred many prospective entrants to the market. What have been missing are developer tools that alleviate the costs associated with building the foundational infrastructure—the “plumbing” of their solutions—so they can focus on optimizing the core functionality and bring solutions to market more quickly with less cost. Wind River® is addressing these challenges with new solutions that have the potential to expand the market for IoT by reducing the cost and complexity of development. This document outlines the challenges that IoT poses for developers, and how Wind River solutions can help overcome them.

Freescale Trust Computing and Security in the Smart Grid

Freescale

With the increasing deployment of automated technical solutions in the implementation of automated metering reading (AMR), advanced metering infrastructure (AMI) and smart grid infrastructure, possibilities of security attacks like data hacking, introducing malware in the system and cyber attacks are on the rise as well. Vulnerabilities in AMI devices include non-secure data buses, serial connections or remote access to debug port. The question arises: how can data security and customer privacy in smart meters and smart energy gateways be ensured? This paper talks about how trusted computing helps resolve security issues in implementing the smart grid by providing a clear idea of what elements of the system are trusted—and to what level and why. Freescale solutions that embed trusted computing are also covered.
