I’m sure many XMOS users are already aware of the XCore Exchange Community , the online community where new and experienced users, established third party services partners and XMOS staff members can post technical support requests, contribute to a Question and Answer list, and discuss ideas and projects.
The Q&A section is a recently added feature that helps community members to get answers to specific technical questions related toxCORE multicore microcontrollers, xSOFTip and the xTIMEcomposer design tools. In addition to XCore members and moderators, many XMOS employees visit the Q&A on a regular basis: so your questions will get answered quickly.
The number of questions in the Q&A section is increasing day by day, so community members can search related issues and get the best possible answer to their specific problem. When XMOS Employees and XCore Moderators come across a fix for an issue which they feel may help other community members, they will add it into the Q&A. This means that the “knowledge base” of questions that have already been answered is constantly growing, and you’ll often be able to find a solution, even before posting a question of your own.
Unlike the discussion forums at xcore.com, the Q&A includes the facility for members to up- and down-vote answers, and for the original poster to choose the best answer. So when you visit the Q&A, you can find the right answer to your problem, based on the number of votes an answer has received. And if you want to exchange further thoughts about a particular answer, there’s a ‘Discuss’ button that allows you to open a forum discussion quickly and easily.
We are planning to make some more changes to the XCore Community over the coming weeks to help our community members get more information about xCORE technology.
If you have any suggestions on how we can improve the XCore Community, please share them via the forums at xcore.com, so we all can take the community forward to make it a better platform in answering all our issues.

Our startKIT development board got a flying start last week when the first startKIT Hackathon took place at the XMOS offices. In fact, as you can see from the YouTube video here, in some cases it was literally a "flying start"!
As well as XMOS engineers, we were visited by some guests from partners including Afterthought Software, and by one of the moderators of the XCore Exchange community, where startKIT has already created quite a buzz.
Projects ranged from the "wi-fi controlled rocket launcher", a "startKIT says" game, and a game cube interface, to an audio flanger that could be controlled via the board's capacitive sensors.
Meanwhile, don't forget to visit the startKIT promo page, for your opportunity to win a free board!

It's great to hear that the first phase of standardization for Ethernet AVB (Audio Video Bridging) is complete. We now have an industry standard way of transferring digital audio and video data via Ethernet - the most successful networking technology the world has ever seen.
In case you weren't aware, AVB is the IEEE 802.1 standard that allows the transfer of digital audio and video data over Ethernet. With AVB, products can send multiple media channels simultaneously through a single network connection. Needless to say, as with all communications technologies, standardization and certification are essential with AVB. The ability to seamlessly connect products from multiple vendors is good for customers, creates a broad ecosystem, and moves the concentration of effort away from simple connectivity ("just make it work") to creative thoughts about how to make the most of that connectivity.
The aim with AVB is to leverage the established truth of Metcalfe's Law - that the value of a communications network is proportional to the square of the number of people connected to the system. If we all join the club, we all benefit.
AVB is now a fully-featured standard, including capabilities such as automated QoS, (quality of service) bandwidth allocation and stream tunneling; it also specifies techniques for discovery, enumeration, connection management and control. This rich feature set promises to carry it into industries as diverse as professional audio, automotive, enterprise conferencing and building automation.
Next week we'll be at the 3rd Automotive Ethernet Tech Day in Stuttgart, demonstrating XMOS solutions for AVB, including a system that uses Unshielded Twisted Pair (UTP) cables and Broadcom's BroadrReach technology. We'll also be showing a mixed-use demo that combines CAN data and audio on a single network. At the conference, Thomas Gmeinder of XMOS will be taking a look at the particular technology requirements for manufacturers working on automotive AVB products. If you're attending the event, we look forward to seeing you there. If not, drop back to this page at the end of next week, where we'll have a summary of all the important news!

A few weeks ago I was pleased to present 2013 Bristol University graduate Michael Jewell with this year's XMOS Prize. This annual award goes to the top Computer Science graduate from the University’s four-year degree course.
Since spinning out of the University several years ago, XMOS has continued to collaborate closely with our friends and colleagues there. I myself was a student on the self same Computer Science course, and was even on the receiving end of a prize at the same presentation six years ago!
At XMOS we're proud of our heritage and our close connection with the University. It's important to recognize the achievements of the young engineers of tomorrow and the XMOS Prize allows us to do just that.
At the ceremony in Bristol Michael went on record saying he was delighted by the award, and looked forward to implementing his skills overs the coming years. Here at XMOS we're certain that he has a bright future ahead of him.

This year’s Infocomm show was the busiest ever, with around 35,000 attendees. The event gives professionals in the audiovisual, information communication and systems integration industries a chance to explore tens of thousands of audiovisual products. Amongst them was our latest Ethernet AVB reference design, announced at the show.
The new AVB Daisy-chain (AVB-DC) offering allows the connection of several network-enabled audio and media products without the need for a central AVB switch. This will dramatically reduce AVB installation and infrastructure costs.
The buzz around Ethernet AVB was centered on the AVnu Alliance pavilion, where XMOS was a leading participant. The standard is gaining acceptance rapidly – we spoke to a number of installers and integrators who have already completed commercial installations. There was also much talk of Apple’s announcement that the upcoming OS X Mavericks operating system will include native support for AVB.
We counted a growing number of XMOS-powered products at the show, including beyerdynamic’s Quinta audio conferencing system, the Revo labs Executive Elite Wireless Microphone System, Renkus Heinz digital steerable loudspeakers, , the Pivitec Personal Monitor Mixer, the DSP4YOU 8-channel endpoint module, and our very own AVB Daisy-chain reference design.

A few weeks ago XMOS China hosted a packed seminar on multicore microcontrollers for embedded systems developers in Shenzhen. Over 100 engineers attended the event which ran over two days. Feedback was excellent: particularly well received were the hands-on demonstrations and interactive sessions hosted by local sales manager Wilson Zhang and field applications engineer Quinn Wang.
The excellent turnout and high level of interest illustrates the ‘buzz’ surrounding XMOS in China – and in Asia more broadly – at the moment. We have recently relocated to a new facility in Shenzhen, and strengthened the team not only with the addition of Quinn, but also the appointment of a new regional sales director, David Lee.
At the event the XMOS team demonstrated all of the benefits of the xCORE architecture, including its flexibility, deterministic operation and its ability to eliminate the need for a real-time operating system (RTOS) in many designs. Delegates were drawn from a broad range of market sectors, including consumer products, digital audio and automotive; most attention was drawn by the XMOS solutions for industrial networking, robotics, Ethernet AVB and other forms of time-sensitive networking.
The success of the event means that it’s certainly something we’ll repeat. Watch this space for news of future events near you!

Last week the XMOS team was in Stuttgart at the Automotive Testing Expo, showing off its work on Ethernet AVB with partner EMBAS, which amongst other things is developing AVB using xCORE multicore microcontrollers and BroadR-Reach® technology based on twisted pair infrastructure.
The EMBAS demo created quite a buzz, as did an emerging networking protocol called CAN FD, (Controller Area Network with Flexible Data-rate). This extends the capabilities of the current CAN communications protocol, (which allows devices and microcontrollers to communicate without a host computer), by supporting higher bit-rates. CAN FD has the potential to dramatically enhance the speed and determinism of these networks.
Automotive companies at the show told us they are seeing an increased demand for a variety of applications that require AVB capability ranging from time-sensitive networking and low-cost industrial communication to infotainment and futuristic solutions capable of linking up with the latest wearable technology products. Watch this space!

A few weeks ago we dramatically expanded our range of general purpose multicore microcontrollers, xCORE General Purpose (sometimes known as the L-Series).
We added 4, 6, 10 and 12-core variants to our existing 8 and 16-core products. This means that the L Series now represents the world’s broadest range of deterministic, multicore microcontrollers.
The extended product range gives our customers much greater flexibility to adopt a solution that is scaled to their requirements in terms of computing power and price. From motor control to time-sensitive networking, Ethernet AVB to industrial fieldbus and real-time control, we can now offer a solution for any requirement.
The 4-core device, in particular, gives designers access to a multicore microcontroller with 500MIPS total processing power, at an entry-level price of just $2.95 in 100-unit quantities.
We’ve found that customers have responded really positively to this repositioning, and the concept of multicore microcontrollers. xCORE technology is still at the heart of our business. All that’s changed is how we turn that technology into products.

Over the past few months the Tools team have been busy writing short HowTo Examples, to help developers find answers to their questions on how to use our tools and program xCORE devices.
The first set of 80 examples are now published, and are available within xSOFTip Explorer. You will see them inside the XMOS Examples folders.
This first set include:
- using the debugger to set breakpoints and look at memory.
- using XSCOPE
- using XTA
- Using C and XC to input on a port, output on a port.
- Reading/writing files during execution
- Code profiling
The examples are delivered in the same format as our xSOFTip, so you can find them in the xSOFTip Explorer, read the documentation and import the code examples straight into the tools.
The examples will also be available on xmos.com in a few weeks time. (xSOFTip is online already, at www.xmos.com/resources/xsoftip)
The tools team are continuing to add more examples every week, including those on other areas such as Programming Flash with xFLASH.
