The ARMv8 architecture fully supports 32-bit addressing but allows 64-bit addressing in a special mode.
I remember ARM CTO Mike Muller saying back in 2010 that clients are going to have to become more like servers and take on 64-bit addressing. Obviously the amount of physical memory continues to increase.
Some applications like face recognition within video streams might be candidates for 64-bit addressing on mobiles?
If anyone can think of others please chime in.
The 64-bit extensions primarily give you an extended addressing capability and presumably there is some price to pay for this in power consumption - moving around 64-bit addresses costs more energy and also worsens cache hit rates than working with 32-bit addresses. Unless you need the address space why would a mobile design move to the 64-bit architecture?
It would seem that 2014 is too late for a new Apple design. If the rumors are false, we will again see a new phone at the latest, in September or October. If they are true, and a new phone is out earlier, then the timing is even worse, impossible really.
I can't imagine Apple going without a new chip for the new phone and iPad 5. So either they are still using Samsung for the part, or something is happening that isn't being reported.
EETimes is not targeted at people looking for smart phone reviews. If that is what you want, read any of the hundreds of articles at places like Ars Technica or CNET.
Repeat after me: there is no global Apple conspiracy. An article about a processor taping out is not a global conspiracy. Not mentioning Samsung in every article is not a global conspiracy.
eewiz conveniently identified plenty of EETimes Samsung articles to demonstrate there is no global conspiracy.
I don't know the answer but I suspect not.
It just seems a bit soon to be going to ARMv8 and Cortex-A57. Also ARMv8 is still seems more relevant to server-end than the client end. Although it will come into clients in time no doubt.
It also seems a bit soon as Apple has been developing its own ARMv7-compatible cores rather than taking cores off the shelf.
Still Apple has tendency to be more radical than most companies and it is to be expected that they will make use of an architectural ARMv8 license at some point.
this is the news about a chip release.. which is more relevant to an EE than the features of a new phone, which anyways didnt have any new radical features than incremental software features. Similar chip release news from samsung were always posted in EEtimes. For eg. http://www.eetimes.com/design/microcontroller-mcu/4404719/Samsung-reveals-eight-core-Exynos-processor
I have been thinking the same, Why is there not a big article in eetimes about what Samsung showed in their Thursday's unveiling of new Galaxy phone. If it were apple, there will be a many articles, only thing I see a 2 paragraph saying what's missing.
Bias? or paid by apple or not paid by Samsung?
I am sure Intel might be working on 8-10nm designs, FPGA's alreay producing 20nm products and working on 14nm starting next year. Almost all Tier1 companies must be taping out chips in 20nm this year.
But it's kind an interesting that how much people of interested to know about Apple tapeout from an unknown source, than some interesting feature facts of Samsung Galaxy IV released yesterday!
Kudos to Apple!
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.
