Boost network capacity

 IT managers are under increasing pressure to boost network capacity and performance to cope with the data deluge. Networking systems are under a similar form of stress with their performance degrading as new capabilities are added in software. The solution to both needs is next-generation System-on-Chip (SoC) communications processors that combine multiple cores with multiple hardware acceleration engines.

Innovation in automotive IVI is making a lot of heads turn

The speed of innovation in automotive IVI is making a lot of heads turn. No question, Linux OS and Android are the engines for change.

The open source software movement has forever transformed the mobile device landscape. Consumers are able to do things today that 10 years ago were unimaginable. Just when smartphone and tablet users are comfortable using their devices in their daily lives, another industry is about to be transformed. The technology enabled by open source in this industry might be even more impressive than what we’ve just experienced in the smartphone industry.
 The industry is automotive, and already open source software has made significant inroads in how both driver and passenger interact within the automobile. Open source stalwarts Linuxand Google are making significant contributions not only in the user/driver experience, but also in safety-critical operations, vehicle-to-vehicle communications, and automobile-to-cloudinteractions.

Figure 1: Software complexity in IVI systems continues to grow. Today, the IVI system of an S-Class Mercedes has 100m lines of code. By 2015, it is expected to be 300m. A Linux-based solution, capable of scaling to handle the complexity, is mandatory.

Figure 3: There are several ways to include Android (Android apps) in a Linux-based IVI solution. One method, which is becoming increasingly more popular, is using Linux Container Architecture. Here, Android sits as a guest OS on top of the Linux kernel. Privileges and permissions are tightly controlled.

How about dimension in operating systems?..

Single board computer, Industrial pc, Console server

Given the increased complexity of processors and applications, the current generation of Operating Systems (OSs) focuses mostly on software integrity while partially neglecting the need to extract maximum performance out of the existing hardware.

Processors perform as well as OSs allow them to. A computing platform,  or otherwise, consists of not only physical resources – memory, CPU cores, peripherals, and buses – managed with some success by resource partitioning (virtualization), but also performance resources such as CPU cycles, clock speed, memory and I/O bandwidth, and main/cache memory space. These resources are managed by ancient methods like priority or time slices or not managed at all. As a result, processors are underutilized and consume too much energy, robbing them of their true performance potential.

Embedded industry M2M

Industrial PC, Console server, Panel PC

Machine-to-Machine (M2M) communications strategies and cloud computing are transforming industrial interconnects from an assortment of fragmented, proprietary technologies to open standards easily integrated into new designs. This new direction in M2M connectivity enables a wide range of applications and services by exchanging real-time data between remote devices, one or more central servers, and authorized third parties.

M2M technology allows embedded design teams to contain costs, improve security, enable remote management, and maximize system availability. The major goal of M2M communications is to combine real-time data from remote devices with enterprise applications to automate everyday company decisions and thus optimize industrial output and lower operating costs.

In this issue of Industrial Embedded Systems, we asked contributors to take a look at the networking, sensing, and computing issues affecting embedded design for industrial applications. For example, Mike Ueland, senior VP and general manager at Telit Wireless Solutions North America, describes the benefits and cost savings associated with M2M connections for remotely monitoring and managing assets. Mike outlines several good reasons to support an M2M industrial application based on cellular technology. In an in-depth interview covering intelligent networking technologies, Tom Barber, director of marketing at Silicon Labs, presents a new wireless microcontrollerproduct that fulfills the requirements of embedded applications with RF connectivity. Tom also highlights the new capabilities offered in low-power mesh networks resulting from Silicon Labs’ acquisition of Ember Corporation. Expanding the discussion, Shaye Shayegani, senior field applications engineer at Lantronix, answers questions on the security and adaptability of industrial networking modules. Shaye addresses the major connectivity challenges that industrial customers are dealing with right now.

Changing the subject to the sensitivity and stability of brushless DC motors in industrial applications, Honeywell Sensing and Control’s Joshua Edberg, senior global marketing manager in the Magnetic Sensors division, and Fred Hintz, engineering manager in the Speed and Position Sensors division, dispel three myths of chopper stabilization techniques. Covering another topic essential to factory settings, Karim Wassef, director of DC-DC product line management at GE Energy’s Power Electronics division, answers questions about the power sources available to operate in hostile conditions such as extended temperatures or corrosive environments. In a software-related topic, Doug Jones and Brian McKay, marketing managers at MathWorks, cover the advantages Model-Based Design offers for complex industrial control systems, allowing users to simulate, test, and debug circuitry before committing it to hardware.
