The embedded computer future is active

The embedded computer future is active

At the Fleck Connection Congress, Intersil's embedded computer elaborated on active cable interconnects as a way to address many of the challenges. In active cables, small silicon ICs are embedded in each end. The silicon restores signals that have been attenuated over the length of the cable. Active copper-based cables can be used for the lowest cost and lowest power applications while active optical fiber-based cables are ideal for the longest distances. Data centers are already embracing active cables to overcome embedded computer of existing solutions. The consumer embedded computer is more cost sensitive and thus more hesitant to use active cables, but the driving need for ultra-thin product profiles and I/O density are making active cables the only option.

The embedded Analog Front End (AFE) as a new device

The ubiquitous use of sensors in our embedded smart devices – from cell phones to industrial equipment and even medical devices – has increased the need for more intelligent sensor technologies that are more versatile, lower overall costs, and require fewer resources to develop and maintain.

However, Many of today's embedded systems incorporate multiple analog sensors that make devices more intelligent, and provide users with an array of information resulting in improved efficiency or added convenience. The Analog Front End (AFE), allowing the connection of the sensor to the digital world of the MCU, is often an assumed "burden" in designing sensor interface circuits. However, the latest concept in a configurable AFE, integrated into a single package, is helping systems designers overcome sensor integration challenges associated with tuning and sensor drift, thereby reducing time to market. The following embedded discussion examines how the versatility of such a technology allows the designer to tune and debug AFE characteristics on the fly, automate trimming and adjust for sensor drift, and add scalability to support multiple sensor types with a single platform.

Rich meal on open source market with embedded techniques

Embedded platform distributions – To eat or not eat?

Evaluating options, refining the OSS palate

Finding potentially useful code represents only half the challenge. Developers must also vet discovered code across a variety of parameters to determine if it is technically and legally viable. Factors to consider include code size, language, and quality; community history and dynamics; software licensing; and provenance.

Code size – Legacy embedded designs face severe constraints on code size. While tumbling DRAM and flash memory prices have made parsimonious provisioning a concern of the past, embedded software still benefits from compact code. Memory and storage eaten up by utility and infrastructure code are unavailable for differentiating software and for end-user content.

Because OSS starts with source code, the memory footprint of a given project or softwarecomponent isn’t always obvious. Moreover, today’s device-based software stacks can contain ingredients cooked up in traditional compiled/assembled languages (C, C++, assembly), byte-code executed Java, and scripted/interpreted languages (PHP, Python, Lua, and so on).

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 2: An example of smartphone in-dash tethering: Drivers use the same smartphone apps in the vehicle as they do on their own smartphone, which provides a great deal of familiarity.

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?..

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, embedded 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.
