Jamie Little   Since the Nucleus Innovate Program was launched in November of last year, we’ve recieved dozens of Qualification Forms and many small companies have been approved for free licenses. While the popularity of the program has been exciting, the array of customer applications we’re seeing from the Innovate Program is equally as exciting! For example, some of the market segments represented … Read More

Munich conferences

Posted by Colin Walls

Colin Walls I attend quite a few conferences, taking any opportunity to speak about embedded software matters. Although such events take place throughout the year, there are two notable periods: Summer [July/August], when everything goes very quiet, and early Fall [late September and October], when everything goes mad. We are just beginning the “quiet” period. But there were a couple of events scheduled … Read More

Nucleus, RTOS

26 Jun, 2013

Ricardo Anguiano So, what sorts of things can you create with Mentor Graphics’ embedded software development tools and platforms?  How about a self-balancing robot named Stella?  The Nucleus ReadyStart development platform, which includes the Nucleus RTOS, Sourcery CodeBench IDE and toolchain and Sourcery Analyzer performance and analysis tool, was used in the development of Stella. Stella the robot is an inherently … Read More

Using an SMTP client

Posted by Colin Walls

Colin Walls I always find it satisfying to see simple solutions to apparently complex problems and the world of embedded software certainly lends itself to some creativity. My concept of “simple” is quite broad, but essentially encompasses anything that is easy to understand [for me] and ideally avoids reinvention of any wheels. A while ago, I wrote about incorporating a Web server [HTTP server actually] … Read More

Anil Khanna In February, I had blogged about the emergence of the smart energy arena, made up of an ecosystem stretching from the utility to your home including connected devices such as data concentrators, smart meters, home gateways, smart appliances etc. A common standard that outlines the requirements regarding connectivity and intelligent communication between these devices is the Smart Energy Profile (SEP) … Read More

When an Innovative Plan Works!

Posted by Jamie Little

Jamie Little Free Nucleus RTOS source code? Just a few years ago if you would have told me that Mentor Graphics would be offering free-source-code for one of the most successful, popular and distributed RTOS’s in the world, I would not have believed it. Yet, for the last few quarters, Mentor is doing just that! The Nucleus Innovate Program was announced November 2012 and adoption is picking up quickly! To date, … Read More

Jamie Little In the high-tech market, the IoT is driving connectivity requirements in devices across many segments. Considering the number of embedded medical devices hospital, you can quickly imagine areas where Wi-Fi connectivity can be used to connect devices, patients, administrators and doctors. For example, Wi-Fi can be applicable in the doctor’s office, in the operating room, at the nurse’s station, in the … Read More

Anil Khanna The concept of machine-to-machine communication (M2M) is the foundation of the Internet of Things (IoT). Of the few core technologies that help facilitate this, zero configuration networking (zeroconf) is key. Zero configuration networking is what allows your personal, portable wireless devices to talk to other similar devices – without any additional setup required from the user. In the pre-zeroconf … Read More

Anil Khanna Nucleus, our flagship RTOS offering has been around for several years now. In this time, it has been designed into more than 3 billion embedded devices in various applications such as mobile, medical, consumer electronics, industrial and more! The phrase “been there done that” could not be more appropriate to Nucleus. Regardless, when it came time to design yet another cool demo, our engineers were … Read More

What is an FPGA?

Posted by Colin Walls

Colin Walls In the early days of embedded systems, software engineers typically had some understanding of hardware design. Indeed, in many cases, it was the hardware designer who implemented the software. Over the years, as the amount of software development has increased, engineers have become less and less “hardware aware”. I find this transition interesting from the viewpoint of an embedded software … Read More

Embedded World 2013

Posted by Colin Walls

Colin Walls This week I am on my annual pilgrimage to Nuremberg, Germany to attend Embedded World. This is the first major conference of the year that covers embedded software and is, I am sure, now the largest event serving this community anywhere in the world. I have written about past visits and this year’s trip will be quite similar, except that I will be rather busy … Most years I have had one … Read More

Kamran Shah The Mentor Embedded team will be at Embedded World in Nuremburg Germany this week. In addition to a number of demos at the Expo (Hall 5, Booth 324) we are presenting a number of sessions as well. On Tuesday Colin Walls will give two presentations: His first session is titled “Power Management in Embedded Systems”. This is part of Session 4: System Level Design and will be from 3:15 pm to … Read More

Jamie Little NXP has joined the Nucleus Innovate Program with its line of LPC ARM Cortex M4 family of microcontroller devices. The first Nucleus BSP available for NXP will be on the Hitex LPC4350 evaluation board. Just to mention a few of the onboard goodies, the LPC4350 has speeds up to 204MHz, USB, LCD, Ethernet with 1MB FLASH and 264kb SRAM, making the LPC3450 a very capable development platform. Moreover, the … Read More

Reentrant write-only ports

Posted by Colin Walls

Colin Walls Recently I posted about the challenges of using a write only port. Then I followed that up with another posting that illustrated the use of C++ to encapsulate the necessary coding nastiness. Hopefully, these two postings conveyed the general ideas – defining the problem and outlining a solution. However, one aspect of the solution was not addressed: the proposed code was not reentrant … Reentrancy … Read More
