Embedding multicore PCs for robotics & industrial control
By combining an RTOS and the Windows OS on separate processors in a multicore-based PC platform, builders of robotics, industrial and machine control systems can achieve real time performance while at the same time lowering costs by reducing the number of computers in the system.

Motor Control/Sensors

Motor control in air conditioners with dual sensor less FOC and active PFC
Improved energy efficiency and reduced system costs are the driving factors in modern motor control designs. Sophisticated motor control concepts with sensor less Field Oriented Control (FOC) and Power Factor Correction (PFC) help to fulfill these demands. The article shows how these concepts can be used in an air conditioner design for vehicles.

Managing Complex SoC verification using plan based verification techniques
Meeting the quality requirements of a complex SoC requires managing large verification projects. In this article, Freescale and STMicroelectronics recount a recent experience with a verification management solution (Incisive Enterprise Manager) from Cadence, for the verification of a 32-bit microcontroller project for the automotive industry.

Training engineers: Designing embedded control systems for auto apps
A new undergraduate course at the University of Michigan focuses on designing embedded control systems for automotive applications like adaptive cruise control.

Networking

Increasing bandwidth in industrial applications with FPGA co-processors
This article discusses the general issues of moving part, or all, of a DSP industrial application onto an FPGA using system software design tools. Using an FPGA and automated design software, design engineers have the ability to optimize system performance in ways not possible with a traditional DSP.

Isolate your interface to communicate safely and better (Part 2 of 2)
Understand how galvanic isolation of signal and power can improve performance and safety of basic interfaces such as RS-485

Robotics and Prototyping

Layering it on--a new approach to automating system tests
Here's a layered approach to testing that uses pluggable software components to assure scalability and portability.

Variations on a flexible array theme
Different dialects of C and C++ support different forms of flexible array members. Unfortunately, the more expressive forms are the less portable ones.
