Chapter 7 of the book: Introduction to Mechatronics and Measurement Systems
This text has been developed for the introductory courses on microcontrollers taught by the Institute of Computer Engineering at the Vienna University of Technology. It introduces undergraduate students to the ﬁeld of microcontrollers – what they are, how they work, how they interface with their I/O components, and what considerations the programmer has to observe in hardware-based and embedded programming. This text is not intended to teach one particular controller architecture in depth, but should rather give an impression of the many possible architectures and solutions one can come across in today’s microcontrollers. We concentrate, however, on small 8-bit controllers and their most basic features, since they already offer enough variety to achieve our goals.
Section 1 describes the main characteristics that a real-time operating system should have.

Section 3 introduces the languages used for real-time programming and compares the main characteristics.
Section 4 presents and compares different alternatives for the implementation of real-time Java.
The embedded software industry wants microprocessors with increased computing functionality that maintains or reduces space, weight, and power (SWaP). Single core processors were the key embedded industry solution between 1980 and 2000 when large performance increases were being achieved on a yearly basis and were fulfilling the prophecy of Moore's Law. Moore's Law states that "the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years." With the increased transistors, came microprocessors with greater computing throughput while space, weight and power were decreasing. However, this 'free lunch' did not last forever. The additional power required for greater performance improvements became too great starting in 2000. Hence, single core microprocessors are no longer an optimal solution.
This book is intended to fill the need for an intermediate level overview of programming microcontrollers using the C programming language. It is aimed specifically at two groups of readers who have different, yet overlapping needs. The first group are familiar with C but require an examination of the general nature of microcontrollers: what they are, how they behave and how best to use the C language to program them. The second group are familiar with microcontrollers but are new to the C programming language and wish to use C for microcontroller development projects. First Steps with Embedded Systems will be useful both as an introduction to microcontroller programming for intermediate level post-secondary programs and as a guide for developers coping with the growth and change of the microcontroller industry.
This book is intended as a hands-on guide for anyone planning to use the Philips LPC2000 family of microcontrollers in a new design. It is laid out both as a reference book and as a tutorial. It is assumed that you have some experience in programming microcontrollers for embedded systems and are familiar with the C language. The bulk of technical information is spread over the first four chapters, which should be read in order if you are completely new to the LPC2000 and the ARM7 CPU.
This application report describes how to compare ultralow-power MCUs. It discusses the key differences between popular low-power MCUs and how to interpret features and specifications and apply them to application requirements
This book is about writing Linux device drivers. It covers the design and development of major device classes supported by the kernel, including those I missed during my Linux-on-Watch days. The discussion of each driver family starts by looking at the corresponding technology, moves on to develop a practical example, and ends by looking at relevant kernel source files. Before foraying into the world of device drivers, however, this book introduces you to the kernel and discusses the important features of 2.6 Linux, emphasizing those portions that are of special interest to device driver writers.
In today’s increasingly interconnected world, security breaches are becoming ever more prevalent, with escalating complexity challenges.

As IoT rapidly grows into new markets such as MHealth, Agriculture 4.0, and building automation, new questions are being raised about the energy required to support its growth. Within the industry, we see a broad spectrum of power requirements.
The low-noise system architecture and the tailored frequency response employed in the HDO4000A, HDO6000A, HDO8000A and MDA800A series provides the foundation for enhancing ADC sample rates through additional techniques. In this case, carefully constructed filters combined with a pristine front-end amplifier and a frequency response carefully limited to 1 GHz provide the opportunity to provide more measurement precision than would otherwise be possible. The technique utilized to achieve higher measurement precision is interpolation, and this technique is used by default as an Enhanced Sample Rate up to 10 GS/s. By integrating the Enhanced Sample Rate functionality with the normal Timebase controls for Sample Rate, Time and Acquisition Memory adjustment, the oscilloscopes are optimized for best waveform signal fidelity in all situations.
Demystifying digital signal processing (DSP) programming: The ease in realizing implementations with TI DSPs
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.
Rising data communication rates are driving the need for very high-bandwidth real-time oscilloscopes in the range of 60-70 GHz. These instruments are essential for validating and debugging new designs in coherent optical modulation analysis, high energy physics research, high speed data communications and other areas. With the DPO70000SX Performance Oscilloscope series, Tektronix delivers real-time signal acquisition with an ultra-high bandwidth of 70 GHz, along with a real-time sample rate of 200 GS/s (5ps/sample resolution), making it ideal for such applications.

This document contains a lot of what you need to know to get the most out of the MSP430. The MSP430 line is renowned for it's low power usage, and to really utilize it well you have to architect your software to be an interrupt driven device that utilizes the low power modes.
[Best paper on Reed-Solomon error correction I have ever read -- and it's from the BBC!] Reed-Solomon error correction has several applications in broadcasting,in particular forming part of the specification for the ETSI digital terrestrial television standard, known as DVB-T. Hardware implementations of coders and decoders for Reed-Solomon error correction are complicated and require some knowledge of the theory of Galois fields on which they are based. This note describes the underlying mathematics and the algorithms used for coding and decoding,with particular emphasis on their realisation in logic circuits. Worked examples are provided to illustrate the processes involved.
