This is good news for consumers worldwide.  More competition means better quality and lower price. I agree with the comment made around tablets following the smartphones trend. The question is: what is the next big thing after tablets? Could Apple do it again, or would someone else come up with a surprise disruptive product this time?

Heterogeneous multi-processing (HMP)

Who will be next to offer ARM quad-core sotluions with heterogenous multi-processing capability? 

Will HMP make such a big difference in your opinion?

So, Ian Drew from ARM tweets, answering my questions (who's next to offer HMP): "a few more are coming along." 

Great. I wonder if we can count on Samsung and Qualcomm to fall into that category of soon to offer HMP.

But more importantly, to my question, "How difficult is it to add HMP capability? Beyond getting software and RTL that enables HMP from ARM?" Ian just tweets back criptically: "it's all coming."

As I wrote in the story, "MediaTek's competitors have also access to the same software and RTL that enables HMP from ARM." What makes one's HMP-capable multicore better than others? Any idea?

I think we'll probably see this in market leaders at some point. MediaTek may make a few waves with it right now, but it isn't proprietary. If it is good, someone with market leverage will implement it in their leading products. MediaTek did a good job finding something to get a press release out there, but this probably isn't going to have a big impact for them.

The tablet market is flooded with smaller name tablets and people are getting a bit jaded. MediaTek has a lot of work ahead of them if they're going to compete on the shelves of the big box stores. That name recognition goes a long way towards a sale.

Knowing MTK and how it became a well-respected powerhouse in the smartphone chip market, I wouldn't understimate them.

Yeah, I didn't mean to make it sound like they were a nobody. I kind of think they might be in a similar position to when LG started making waves in the states. They were already big overseas, but people here just hadn't heard of them. Now they're everywhere. 

I still don't think this(heterogeneus processing) will be the defining fact for their growth in the tablet market. If anythign it will be solid physical construction and battery life.

It seems to me that clustered migration....where a software is moved between a cluster of little cores up to a cluster of big cores and then back under an extension of dynamic voltage and frequency scaling....is simplest and provides what is essentially a uniprocessor programming model.

This means effectively no change for the SoC user but better computation efficiency and the cost of a little silicon.

One you start allowing multiple big-little pairs to exist...or to allow tasks to run on cores as appropriate and as avavilable then the operating system software scheduler becomes vital.

Indeed this could start to become an Android or iOS play rather than an SoC vendor play.

I expect to see Linaro start to be making some Software Schedular developments to enable the more advanced forms of heterogeneous processing.

Peter, that's a really good point. MTK says that it developed its own scheduler for this...but it's true that OS-level involvement would come into play...

ARM outlined these two approaches (clustered and MP) at ARM Tech Con last year:

See http://www.eetimes.com/document.asp?doc_id=1262724

They made it clear the clustered approach was going to be the first out the chute and the MP approach would take a little more time in testing. Thus the Samsung Octa had a time to market advantage but the MP tech wasn't ready yet.

Going forward I would expect most SoCs will take advataage of the MP approach as long as it shows efficiency benefits. Hey, its a nice give away from ARM.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
