BTW if you go to TI and type in Energy Harvesting in the search boc you will get apps, training videos and suggested ccomponents. There is still lots of original research going on. It's one of the areas I have research in for commercial apps.

Rookie

If you want to play a bit with energy harvesting -- here is a start..

http://www.ti.com/tool/ez430-rf2500-seh

Lots out there tho

Rookie

See Texas Instruments Energy Harvesting for one.

Rookie

Yes - there are some systems that run of scavenged power. Very low power devices and they get their energy from radio waves, motion, heat or solar.

 

Blogger

MCLAUS: Is anybody successfully...

Yes -- many remote sensor networks exist. Old technolgy actually... many styles.

Rookie

Is anybody successfully running a processor that can harvest energy from the environment without being wired for power from someplace and without needed some big infrastructure (solor arrays and converters etc)?  That would be a slick way to put sensors where they could be very useful. 

Rookie

Paraphrasing Brian form Monday, Everthing eventually goes to analogue.

Well, I will see everyone here tomorrow. Lots to get through tomorrow, so I will have to talk fast!!

Blogger

@mclaus - Yes that one would be worth pattenting, just like perpetual motion!

Blogger

Ah, transeding physic,s the dream of every Computer Scientist.

@Jeffrey - agree 100%. It is a system design problem and system is HW + SW

Blogger

now THAT would be the killer app.

Rookie

"it is possible for the Hypervisor to have guaranteed performance" 100% agree. But you need to design for this and pick the right kind of HV.

Correct. The system has to contain enough resources to meet the needs of the application. It can cvreate them out of thin air.

Blogger

So - the hypervisor can stop preemption from happening.

Blogger

There must still be some kind of prioritization defined to guide the hypervisior if there are requests for more hw resoure than is availabale, correct?

Rookie

@Juan - another thing to consider is that the hypervisor gets first crack at all of the interupts. It can decide to delay sending them to the OS if real-time tasks need to complete.

Blogger

They operate as an independent company and still support other computer archs such as those made by Freescale, TI, etc.

 

@Juan - if you have a need for a process, then the hypervisor can ensure access to the necessary HW - if it exists. That is perhaps the key. It is all part of the aplication development, but it is possible for the Hypervisor to have guaranteed performance.

Blogger

Geeesh - missed that completely....:>(

 

Rookie

July 2009 

http://www.windriver.com/news/press/pr.html?ID=7081

@mclaus - that was a couple of years ago now.

 

Blogger

This is a strong statement "With virtualization a time critical trask can be guaranteed access to the resources it needs." Has it been proven theoretically?

After all, by definition, the actual hardware is shared among multiple applications.

Rookie

Type 2 HV for sure (I think this a like clustering), but I don't see how you disribute a type 1. May just be my ignorance.

Did Intel acquire WindRiver?  When did that happen?

 

Rookie

Please let me know if I missed any questions. Difficult to keep up with all of them at the start of the chat session.

Blogger

@Jeffrey. Hypervisors can be distributed in the same way that OSs can. Not sure exactly how they have implemented it.

Blogger

@mclaus. I have read a lot of stuff recently about almost fights going on about the comms to use. Perhaps multiple busses will be the answer each tailored to either real-time or large data.

Blogger

OK I can see that on a si=gle muticore chip but with INtime there is no single hypervisor.

@Jeffrey - yes , at least an attempt at it.

Blogger

Thanks Rance - nice definition.

Blogger

It will always be possible to load apps onto a system that may cripple its performance - for example. You could say this is one of the differences between iTunes and Android. Apple attempts to control things to make them more consistent whereas Google takes a hands off approach.

Blogger

is this the answer to my question? Virtualization can help with determinism - especially if the hypervisor is partly copntained in HW. With virtualization a time critical trask can be guaranteed access to the resources it needs.

Frank P - "What ensures that the hypervisor isolates a certain critical system to a certain processr or virtual machine?" - Evidence presented to a qualified and objective third party to validate the claims that the hypervisor is correctly implemented. Ideally this evidence includes a mathematical proof that the hypervisor (hardware and software) simulates multiple independent machines that have no interference between them.

Rookie

Thanks Brian and Alex.

Rookie

Integrated System Vendors

Blogger

So what is the underlying communication systems - something that can be fast and detertminsitic enough for suspension control and also handle media streaming and wide area network latency issues?

Rookie

Virtualization can help with determinism - especially if the hypervisor is partly copntained in HW. With virtualization a time critical trask can be guaranteed access to the resources it needs.

Blogger

thanks for the links Alex!

Rookie

On slide 5, what is ISV. Should it be ESV: Ecosystem of system vendors?

 

Rookie

Brian, what happens to the determinism in a Distributed Computing System like INtime when you start making new connections that were not thought of at the design time as you were describing on Monday?

The hypervisor has control over all of the physical HW. No app can gain access to it without going through the hypervisor.

Rookie

Thanks lecture Brian and Alex. 

Rookie

I am beginning to see advantages to virtualization. However, I also see host of issues related to deterministic behavior and hard real time issues.

 

Rookie

Thanks Brian and Alex for another interesting session and more ideas to look at later.

See all tomorrow

Rookie

Yes - everyone is working in this area and forming alliances. That is testament to why the cooperation of people in the foodchain is so necessary.

 

Blogger

Thanks Brian & Alex.

 

Rookie

What ensures that the hypervisor isolates a certain critical system to a certain processr or virtual machine?

 

Rookie

Brain, nice presentation. Thanks

Rookie

Thank you for today's lecture Brian

Rookie

I know they are doing stuff to advance the two areas seperately.  I'm not aware of anybody putting both of these application spaces into  single network within the car.

 

Rookie

All the Well Known Car Co, ar doing all of this. Bosch, Conti, Delphi. IC companies etc.

Rookie

Brian - are there initiatives in the automotive space that integrate the engine/suspension/transmisssion control networks (FlexRay/CAN/etc), with the Infotainment networks into a single architecture?  Who is doing that work?

Rookie

I object - don't blame the Brits for this!

I'm GOBsmacked

INtime Distributed RTOS is a fully preemptive 32-bit operating system, supporting 256 priority levels and round robin scheduling that can run several kernels at a time, each running process loop times of <50μS to meet the needs of the most sophisticated control SW applications. It features a unique Inter Process Communication (IPC) technology called GOBsnet that enables applications to run without modification on different system configurations, spanning the range from single-core processors to multi-core processor systems to multi-platform systems. INtime Distributed RTOS is based on INtime for Windows core technology, a tried and proven 32-bit RTOS for PCs that has been running some of the most complex and mission critical applications in the Industry for over 15 years.

Rookie

GOBSNet, sounds like RT CORBA?

Do you have links to information on INtime? There are several referenced on Google which are not what you are refering to.

Rookie

What is the Layered approach called? GOBSNet?

Rookie

@Bill T: AGreed actually I designed MES architectures so data collection systems could maintain local data and schedules and "catch up" when communications came back on line. Good point.

Rookie

So how do you get a scalable Device Architecure if you do not have a scalable or inteoprable communication protocol. Even OPC-UA is limited in its interoprability scope, though it is very flexible.

Or which pillar do you need the most help with and which do you have well under control.

As is being said, all four pillars are extremely important. I believe connectivity could perhaps be sacrificed to a greater degree than the others, if need be, as long as the local, immediate task could successfully continue.

 

Rookie

Maybe we should say that if one of the pillars is not adequate to the task -- the rest don't matter.

Rookie

I think a better diagram is needed. Looks like a type 2 to me.

Security and performance are importants

Rookie

For me, as a system designer connectivity is important.  We can manage performance and manageability issues.

Rookie

Connectivity is the biggest hurdle, the rest can be managed when that is solved.

Rookie

security is top, then manageability and performance. product operates in sfaety critical systems
