http://www.timlab.it/Download/SESSIO...E_Workshop.pdf
If that link is too slow (or no longer works) you can try using the Google cache: http://www.google.com/search?q=http%...E_Workshop.pdf Major revelations include: - MSM8960's Krait core is running at 1.5-1.7GHz and it's only the APQ8064/MSM8974 that will reach 2.0-2.5GHz. - 800MHz Cortex-A5 MSM7227A (& absurdly named 600MHz MSM7225A SKU) on 45nm for ultra-low-cost smartphones. - MDM9615 (28nm shrink of the 100Mbps LTE MDM9600) is slated for Q2 2012 production which is earlier than expected. - Unannounced MSM8974 is a combination of the APQ8064 application processor and the 150Mbps LTE MDM9625 baseband. - MSM8230 will only support 50Mbps LTE/21Mbps HSPA+ rather than 100Mbps LTE/42Mbps HSPA+ like the MSM8960. - Unconfirmed MSM8228 ("in planning"): 14.4Mbps HSPA+/2x1.0-1.2GHz Krait/512KB L2/720p video/Adreno 305. - All future Qualcomm devices with LTE support TD-SCDMA for China Mobile. Analysis: - I'm willing to bet the iPhone 6 will use the MDM9615. Previously it was unclear if it would be ready on time, but if it's currently on schedule to be in mass production by Q2 2012 and Apple is the lead customer, it could be ready for an iPhone 6 in late September 2012. It's also the only solution that supports not only GSM/HSPA/LTE but also CDMA (for Verizon) and TD-SCDMA (for China Mobile). - The 45nm MSM7227A is a very attractive solution for the ultra-low-cost market but it'll face tough competition from 40nm 1xCortex-A9 solutions from Broadcom and ST-Ericsson (which should be nearly as cheap since A9 isn't much bigger than A5 compared to a 3G baseband and LPDDR2 hopefully won't be noticeably more expensive than LPDDR1 in that timeframe). The package isn't clear from that presentation (11x11 is insane as you need 12x12 for PoP memory) but if it's fully compatible with the MSM7227 then that's a very big selling point. It also helps that Qualcomm has also indicated they are willing to sacrifice their gross margins for ultra-low-cost smartphones. - The MSM8230 and MSM8228 are both very attractive chips for the mid-range and low-end smartphone markets in their target timeframe and it's nice to see that Qualcomm can apparently scale their LTE architecture all the way from 50Mbps to 150Mbps without paying more die size than necessary. It's not clear if the MSM8974 will be quite as impressive versus competitors but at least this presentation confirms it supports 1080p 60fps (->3D 1080p 30fps) and rather interestingly LPDDR3 (basically doubles data per raw MHz, up to 1600MHz effective versus 1066MHz effective for LPDDR2).

I guess using their architectural license for an improved Cortex-A5 class core wasn't as practical as just licensing the A5 itself.

Finally, an ARMv7 update to MSM7227. Low-end smartphones will finally be able to read websites with flash content, yay (at the expense of dirt-poor performance but whatever).
By the way, is there any way to know if the MSM7227A will have a FPU unit, like its predecessor? They're also sticking to the old-as-hell Adreno 200, apparently with some ~35% higher clocks. I wonder if the Adreno 205 was that much larger.. |

I think Qualcomm have pretty much fixed any holes in their roadmap eh?
Quote:
-How does the Cortex A5 stack up against the current CPU in the MSM7227/7225? (im not sure what they have) -Hopefully that should reduce power consumption significantly and we'll see LTE phones with more than half a day of usable battery life -You mean the baseband is integrated or is it a two chip combination? -I think you mean MSM8930 right? And it makes sense i guess. Its a single core so likely destined for the mid-range market (im not even sure how many of those phones will even need LTE) -Now MSM8228 sounds very nice for a mid-range smartphone. Krait will bring a big boost in CPU power over current dual cores, and should be more power efficient as well. Not everyone needs LTE and this should also result in cost and power savings. Quote:
-If it is compatible with MSM7227 i can see it doing very well. The number of devices which are shipping with MSM7227 right now are staggering. But even if it isnt it should drop costs even further for entry level smartphones. But the Broadcom and ST-E designs with their 800 mhz Cortex A9 class CPU's are still going to be a class ahead so Qualcomm will probably be relegated to the lower end of the low-cost market! Quote:

I think going from 3 to 5 bands today to 15-20 bands isn't very realistic. I expect they'll have *at least* one model for the USA (5xHSPA/2xCDMA/USA-LTE), one model for Europe plus some of Asia (5xHSPA/Non-USA-LTE), and one model mostly for China (5xHSPA/TD-SCDMA/TD-LTE). The only way they'll get around this problem is with something like Nujira's Coolteq-l and a wide-band power amplifier (or rather two, one for the bottom bands and one of the top bands). It's possible but not very likely. Quote:

Do you think it's safe to assume that 320 will be nothing more than four 305 cores? |

Somehow I can't think that they'd skip the fpu (though maybe skip neon?). The a5 isn't a massive upgrade in any case, but it should be slightly faster, using even less die area than the arm11, and the whole chip more power efficient. Overall not too bad, though not really an exciting upgrade over the 7227 (but I'd guess even cheaper). btw is this the first Cortex-A5 to appear? In any case looks like the A9 didn't quite make it into the cheap category for smartphones appearing end of 2011 / beginning of 2012. The MSM8228 though will be a massive upgrade for low-end smartphones. |

If a sole A8 is all you have to rely on for flash, you're dead in the water. At the same time, an A8 with some 'accelerator' support can be quite adequate for flash player 10.1 through .3. (where the accelerator requirements are a function of targeted resolutions, of course).

Unless you know for a fact the various 'media accelerators' in the 3621 (i.e. sgx, c64x, overlay engine, etc) twiddle their thumbs while the device does flash, I'm willing to wager the A8 is not the sole worker under that scenario.

On the matter of pure specs of those SoC's I'm not impressed, of course I'm talking about high-end.
- No quad-core CPU until 2013, too late IMO(at least from marketing POV) - Clock speed's seem low, although without informations on IPC of Krait it's hard to tell what kind of performance we can expect. Definitely faster than A9, but how will it fare against A15? - GPU numbers and dual channel memory support should mean quite a boost in performance with 225. Will it be enough in 2012? Compared to 220(which is actually leading in many GLBenchmark subtests) this could give us something on the ipad2 level, although DX 9.3 is worrying considering windows 8 support, but this could still change before the release. - Adreno 305, from the numbers it looks almost like 220. So with improved drivers it should be more than enough for higher-mid/lower-high end devices. - Adreno 320, almost 2x faster than 225 with dual-channel LPDDR3. Sound impressive, but still not on 'Rouge' level. More interesting things that I would like to know: - Wi-Fi Display support coming with recently announced connectivity chips. Will it be used by those new SoC's? - Will adreno 225, 305, 320 support OpenGL ES '3.0'? |

Yeah, I've already seen this presentation. Let's wait and see what Krait will really offer. Maybe they really managed to develop better CPU than A15, although that is rather unlikely.

Not to start rumors about that last bit, but that might not then be their longer-term solution.

Is there an advantage in integrating the baseband with the application processor?
Or how common is the integrated approach? Probably not common since a big volume vendor like Apple is shipping baseband separately from their A4 chips? What about HTC, Samsung, etc.? |

I agree that it may not make much sense at the high-end and tablet space. However, that may change with LTE since the area and cost of a separate modem can be prohibitive. |

1) Qualcomm is the market leader. 2) All Nokia S60 devices with 10.2Mbps HSPA (i.e. a truckload of them) use the same custom 45nm integrated baseband from TI. I believe in the past some of their solutions were SiPs but this one is definitely a SoC as indicated by Slide 11 of this presentation: http://www.ti.com/corp/docs/investor...fs/Ritchie.pdf 3) Broadcom is also shipping a 3G baseband in (large) volume to Samsung with a dedicated 312MHz ARM11 application processor next to the 208MHz ARM9 modem: http://www.eetrend.com/files-eetrend...0datasheet.pdf - the BCM2157 is a similar chip targeted at Android that boosts the ARM11 clock speed to 500MHz+ among other things. They are also sampling Cortex-A9 chips both standalone and integrated (with a focus on the latter going forward). 4) Marvell ships a variety of integrated solutions including the PXA910 and PXA920: http://www.marvell.com/cn/platforms/...form-Brief.pdf And this is only counting chips with a dedicated ARM core for application processing (thus excluding the vast majority of feature phones which reuse the modem ARM core to run the OS). Other companies that will soon be shipping integrated solutions with a dedicated application processor include: 5) ST-Ericsson with the U8500. Ironically, some customers don't want the Nokia-designed 14.4Mbps baseband and would rather use the EMP-designed 21.6Mbps M5730 baseband next to it. In theory, that solution is called the U9500. While thz A9540 and A9600 are discrete, the U4500 is integrated and should be very high volume. They've also got integrated derivatives on their 28nm roadmap. 6) Mediatek with the MT6573 (7.2Mbps HSUPA baseband with a dedicated 650MHz ARM11). Actually Intel and NVIDIA aren't being too aggressive with baseband integration. The main reasoning behind their respective acquisitions was bundling and being able to provide direct support for the whole platform. I'd expect Intel to integrate a LTE baseband into their second-generation 22nm SoC and NVIDIA to include one in a lower-end derivative on 20nm... but not before. Quote:
The only thing ridiculous about LTE is the number of power amplifiers required if you want to support multiple countries or even sometimes just multiple operators in the same country. If anything, that makes modules an even more attractive solution for tablet manufacturers.

Different bands mainly? So far, I've only heard of Verizon and AT&T ramping up. It seems a lot of operators are touting HSPA+ coverage now, with claims of 42 Mbps speeds in some areas. Are LTE devices going to be interoperable with SIM unlocking? I've heard suggestions that Verizon will find ways to lock devices to their network and it sounded like something beyond SIM locking. |

You wouldn't claim Atheros was acquired just for easier bundling with MSM chips, for instance; even though it'll take a few more generations before full WiFi is integrated into the MSM and MDM series of chips and even longer before the APQ series gets that. Quote:
With everyone racing to not only compete with Apple on features but also on price and profit margin, I expect at least high-end smartphones to prefer integrated basebands in the future for their LTE solutions. |

Wondering if the firmware can be upgraded or downgraded independently, as is the case now for jailbreaks.
Or would integrated designs make this tougher? Apple may be using Qualcom basebands but looks like they're going to roll their own APU. |

I could see Qualcomm securing a stake in IMG if they committed to their roadmap, but no buy out would likely be feasible.

Buyout is certainly out of the question, considering Apple and Intel's investments. A small stake is more likely though.
But Qcom licensing IMG would be a big deal. They have lots of volumes, especially in the low end. Also, what are they going to do with their in house gpu IP? |
