CNET has an interesting post up detailing what we can expect in the next generation ARM processor. Just yesterday we took a look at the iPhone 3G’s ARM 11 vs. the new iPhone 3G S’ Cortex ARM8 and the difference was impressive — most impressive. Well, next year is promising a dual-core ARM Cortex A9…!
Icebike sent this in, wondering out loud: “Is it too soon to start speculating on 2010?” And the simple answer is “no, no it’s not!” It’s longstanding practice here at TiPb to wait a polite 1.372 seconds after a new iPhone model is introduced, and then begin with “So, next year–”
That spirit in mind, TiPb can’t help but wonder what this, combined with multi-core PowerVR GPU’s, wrapped up into custom system-on-chips by Papermaster, the PA Semi team, and all those new GPU gurus toiling away in Steve’s basement, means for a 2010 iPhone? (No, I won’t call it an iPhone HD — yet!)
At the very least, I think DC comics is going to have to invent us a faster Flash!
Imagination makes the PowerVR graphics core chip (GPU) that powers the current generations of iPhone and iPod touch handsets. Apple likes them enough to have become a huge licensor and even investor in the company. Well, it’s looking like that investment may pay off for iPhone users in the next generation iPhone and iPod touch (which TiPb is still predicting will hit in July and September respectively).
Even bigger news? It looks like these new multi-core chips will be transparent from the developer’s point of view. That means Apple has far less risk in “fracturing the platform” by adding more GPU firepower to the next gen iPhone. Also, they look to be supporting OpenCL, Apple’s open source implementation that allows GPUs to be treated like CPUs and boost general purpose computing when they’re not throwing polygons and pixels around our favorite games or movies.
Says the Register (via MacRumors):
Without any intervention by the application – and, more importantly, without any intervention by the application’s developer – the driver will pass data to an “MP code scheduler,” which will in turn pass that data to one pipeline scheduler per core, which will then pass it to one thread scheduler per multi-threaded processing engine, which will then manage the threads through the engines as they process the graphics data.
In other words, the SGX543 can have any number of cores from two to sixteen with no change in the driver software or the application. All that complex data/pipeline/thread management is done in hardware. No muss, no fuss.
But a whole lot of “we want it now!”…
We’ve heard before that, among other things, iPhone OS 3.0 would support quad-core processors. Of course, we haven’t seen these processors yet, but now ST-Ericsson and ARM have announced they’ll be giving a private sneak peak at one at Mobile World Congress. (Via MacRumors):
The technological breakthrough is the first of its kind and is based on the ARM(R) Cortex(TM)-A9 multicore processor, which represents a significant leap from previous generations of baseband/application processor architectures by providing unprecedented levels of performance and power efficiency.
Combined with previous rumors of OpenCL support allowing the faster, betterPowerVR graphics cores to boost general processing as well, and 802.11n mobile WiFi chips future iPhone generations could be, as Steve Jobs is so fond of putting it, real screamers.
Better hardware (especially more RAM) could, of course, encourage Apple to allow more 3rd party multi-tasking. Maybe even make the leap to iPhone HD? (In a matt black finish?!)
