I wonder how important multiple cores per design are going to be for ARM as revenue generators. Perhaps they will try and grab more license $ with multiple different cores for each point on the power/processing curve. One would think a single core with 8/4/2 instantiations might be a better approach, but probably less license $...
The A7 seems to be an interesting addition to the family. I wonder if the title of the article should have been ARM-reveals-little pinky instead of little dog. After all, it is part of the ARM and not the canine family. I look forward to seeing the A7s in silicon for the performance and power savings.
Very interesting. Both cores identical in their architecture support but tuned to different power bands. This couldn't have been possible without some good high speed coherent paths between the cores and the memory. It will be upto the kernel layers to do efficient switching between cores in reponse to application load, hmm.. calls for some clever programming.
My understanding is that for identical cores On a chip ARM does offer a slight discount...this would drive down the royalty rate per core if ARM was not able to drive up the base rate!
ARM can try and do that by arguing that newer cores have increased functionality, performance. licensees can resist by saying that too higher royalty rate will make them look elsewhere!
Add in a graphics co-processor and you have little, big, bigger. It's an interesting approach and does make sense. With the graphics co-processor architecture, high-power functions are offloaded from the main processor. With this approach, low-power functions are off loaded from the main processor.
For power efficiency, ARM do the best. It is its key competition. In China, more and more companies start to use ARM architecture IC with embedded Linux to develop products. The ARM core IC has the most large share market in China. It is also my first choice to make the new project.
