For the question on the complexity benefits for Multicore. There was information from Intel (Fred Pollack) in the late 1990's that showed the theoretical basis for multicore benefits. It became known as Pollack's rule.
This show is now over. The audio portion and this chat will be available as an archive. The archives of all the Design News Radio shows are located here.
On RTOS, yes you can run different OS's on different cores. need to be caeful on shared resources. Watch for a new announcement from us in the next few eeeks.
On interupts, in our implemnentations you get to "steer" the interupts to specific cores so you cna have one type hanlded by one and another by a different core. Very important in Gateway applications.
We do an Auto product line called Qorivva and an Industrial line called the PX family ( Both PowerArchitecture based) We also do multicore Entertainment Products based on ARM. (i.MX6 products)
Is Freescale making multicore controllers dedicated to different application areas (automotive, entertaintment, industrial etc) or there is a general purpose one?
On Safety: Two ways, either you can run software that lets one core check the other or for Lock-Step you run identical code and compare results. Excelletn way of detecting potential soft errors.
I guess I better clarify. Vector's OSCan does not yet seem to support dual core Freescale processors. That is you can run the OS on a dual core processor, but the OS only recognized a single processor. To exploit the second processor, you definitely have to setup your own interprocessor communications mechanism
Thanks, I do most with semaphores, so thats not the problem. I graduated 40 years ago, and now I'm on the edge to select a new Controller for my Remote-Home-Conrol system. Multicore would be a preferred choice. Up to now I thought at an ARM. Can we stay in conact plese after the chat? ChristophKastl@yahoo.de
In CAN networking, the OEM generally insist their prefered network os be used. GM LAN, FNOS being examples. Are the developers of these Network OS's supporting the multi cores which Freescale provides?
Does Freescale provide a software framework to the user to quickly adopt your multi-core controllers? More further, is there any industry standard to use multi-core?
One one speaks of safety one thinks of redundancy in the presence of failures. A single multi-core processor is a single point of failure. No redundancy. Does this imply a need for multiple such processors whe redundancy is needed?

We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
