Then there is the problem of real time and deterministic performance over wireless sensor networks, given the fact that the IPv6 protocol many of these devices will connect to is still asynchronous, with no real global clocking mechanism. Specifications such as IEEE 1588have emerged to deal with this but adoption is moving happening slowly. To fill in the gap, wireless network-specific protocols such as WirelessHART, 6LowWPAN, and AODV have been proposed.
The new IPv6 protocol makes available unique URLs that are counted in the billions of billions of billions. Even if every human on the planet had his or her own URL address, the number of URLs still available is essentially infinite, raising the prospect that almost every embedded device in the world will have its own URL. Will sensors with 8- or 16-bit MCUs be up to this challenge, or will 32-bit MCUs dominate?
These are questions that I think need to be addressed and I look forward to hearing from you with your ideas and contributions.
This is the first tutorial in a series on the basics of the Data Distribution Service versus the Java Messaging Service as real time, deterministic mechanisms for linking enterprise systems with distributed microcontrollers, sensors and actuators.
A two part series updates you on wireless mesh networking, comparing traditional approaches such as Zigbee to more deterministic topolologies such as Wireless HART, 6LowWPAN, and adhoc on demand vector routing (AODV). Part 1: The basics.
In this three part series, the authors review the choices available to designers of wireless sensor networks and some of the criteria by which to make the right choice. In Part 1: wireless network protocol basics
With the imminent exhaustion of IPv4 address space, and a mounting number of embedded devices pushing the limits, it is time to move to IPv6. Here's how IPv6 corrects three problem with IPv4 and what you need to know to make the shift.
In the first of a three part series, Praphul Chandra goes into the details of the technical challenges of making wireless ad hoc network protocols such as Bluetooth more secure and how to achieve this goal.
SoC Architecture & Analysis SoC Design begins with architectural concepts and analysis. Sessions in this track will describe the architectural choices, IP integration issues, and system analyses that define the front end of ARMIP-based SoC design.
SoC Design & Verification These sessions will cover key aspects of the design and verification flow for ARM processor-based SoCs, from conceptual frameworks to best practices.
SoC Design for Power & Performance As technology scales for increased circuit density and performance, the need to reduce power consumption increases in significance as designers strive to utilize the advancing silicon capabilities. In these sessions the focus will be on the techniques than can be used to match performance or power targets.
SoC IP SoC design depends upon reusable silicon IP. These sessions will focus on both the IP qualification process and some novel new alternatives in IP for ARM processor-based SoCs.
SoC Verification of Challenging Structures Modern verification methodology has developed primarily in the pure-digital space. But there are many IP blocks in ARMprocessor-based SoCs, from interconnect structures to tightly-integrated mixed-signal functions, that require extensions of the existing verification orthodoxy. Sessions here will examine some of these cases.
