Hey Al.Key, what makes you think it is "implemented quite well"? Do you work for Nvidia to know this? Or do you have access to one to know this? Dont say something before you can vouch for it. Marvell announced it bizillion years before Nvidia. This is what TI does on their OMAP4 with Cortex-M3. I dont know what Nathan is smoking to say that this is "ingenious". He needs to explain or else he sounds "dis-ingenous"
No, it is not big-little. It is much better. The big little had the low power core as A7 while the high power cores were A.15.
What NVIDIA did is different and remarkable. It is the same type of core (so you don't need to write your mp3 player for both types of cores). But IT IS A DIFFERENT TECHNOLOGY PROCESS in the same SoC. A high power and a low power.
Good job NVIDIA.
