Dude! Don't ever do that again! Don't walk into a thread and so cavalierly drop an otherwise innocously looking link only to walk away as if that was all there was to it.
I almost missed your link because it didn't look like there was much to it, but that link has lots of great nuggets of info buried inside.
Please please please next time you find great links like this include a few select quotes from it as well, use flashing lights, arrows, whatever it takes to get some attention to it
I mean look at what they have here:
the eQuad CPU architecture, each processor core can operate as a high-performance core or a very-low-power core, depending on whats needed at the moment. Since all the eQuad cores can adapt to the needs of the user at any given time, theres no need for the dedicated low-power cores found in other multi-core CPU architectures. Remember, the 2.5GHz cores in the L8580 are the mobile industrys fastest, or conversely, at 0.6V in low-power mode, the industrys most battery-friendly.
big.Little just got one-upped right there
And what about this gem:
The NovaThor L8580 is essentially a straight port from 28nm bulk to 28nm FD-SOI of the (very successful) NovaThor L8540, with just a bit of tweaking to fully leverage cool things you can do with FD-SOI, like biasing to increase performance and conserve power.
For the ST-E designers, most of the IP blocks were directly re-used from the bulk design, so the porting to FD-SOI was extremely simple and fast.
Boom, testimonial evidence that supports ST's claim that porting designs from 28nm bulk to FD-SOI really are as simple as claimed.
And what about the results of the port from bulk to FD-SOI?
For the folks designing smartphones and tablets (and ultimately for the end-user), that port to FD-SOI gets the NovaThor L8580:
- CPUs running 35% faster and GPU and multimedia accelerators running 20% faster. In terms of multimedia performance, theyre supporting 1080p video encoding and playback at up to 60 frames per second, 1080p 3D camcorder functionality, displays up to WUXGA (1920×1200) at 60 frames per second and cameras up to 20 megapixels. (Hence their use of the descriptive extraordinary.)
- 25% less power consumption than rival architectures when running at high-performance levels think Cooler Operation.
- A low-power mode can deliver up to 5000 DMIPS at 0.6V more than enough computing power for the majority of applications in everyday use. A key point here is that it enables stable SRAM operation at 0.6V have you heard of anyone matching this? The result is that this low-power mode consumes 50% less power to deliver the same performance compared with alternative solutions in bulk CMOS.
Great link SocketF :thumbsup:
