  • Intel has been especially responsive to Apple’s needs, one source said, because getting an Intel chip into the modem socket on the iPhone would be a major milestone in the chipmaker’s uphill climb in mobile.

    In the long view, the 7630 chip in the iPhone may be seen as a beachhead for Intel. Apple likes the idea of building the phone processor and the LTE modem on the same chip, which would allow for greater power efficiencies in the phone.

    Meanwhile, Apple and Qualcomm have an uneasy relationship, our sources said.

    LTE-Advanced Carrier Aggregation Becoming Standard, But Improved Uplink Now Required

    The most recently announced Apple AAPL +0.00% iPhone 6S, 6S Plus and new Google GOOGL +0.45% Nexus devices all now support Category (Cat) 6 LTE with Carrier Aggregation (CA CA +0.00%). However, one of the biggest weak points of current 4G LTE technology is no longer in the download speeds, but rather the upload speeds. This is because of the mountain of user generated content that is being created on phones. The content created by users is now in extremely high resolutions exceeding 10 Megapixels and going as high as 20 Megapixels. This, combined with the increased usage of video and blanket 4K video capability means that users’ devices are no longer uploading content quickly enough and as a result are burning through battery to try to upload something.

    In places like China, WeChat is driving crazy amounts of upload traffic growth through people sending each other photos and videos as well as posting to their moments pages. Large sporting events are also seeing huge spikes of upload traffic that simply cannot be handled with single carrier uplink. For example, the final game of the NFL season last year saw over 300 GB of uploaded content on a single operator’s network. This is only going to become more drastic as users start using services like Snapchat and Instagram which are extremely upload heavy due to being popular for photo and video uploads. Virtually every social media service on earth allows for the creation and upload of videos, which drives up the demand for upload capacity. Many of these social media services were originally designed for the 3G era and as a result have been choking off the user experience. Others applications that didn’t survive were far ahead of their time, like Qik a video messenger app that simply needed more upload than 3G or early 4G offered.

    Qualcomm Snapdragon comes with the most advanced LTE chip.
    The 820, expected to hit devices in 2016, will feature the all-new X12 LTE modem, which brings CAT 12 down and CAT 13 up speeds (600 and 150 Mbps, respectively) and up to 4 x 4 MIMO downlinks while on an LTE carrier. In plain English, this means fast.

    While Samsung's next generation SOC chips may be less expensive.

    All of the above offer impressive performance improvements over the current generation of SOC chips.

  • Samsung, as LG, has done well to avoid Qualcomm's Snapdragon 810 in its most popular phones. Plagued by overheating controversies, the chip has damaged the reputation both of its maker and many top-end smartphones powered by it. There's no reason to suggest that the Snapdragon 820 will follow suit, though, and from the information shared by SamMobile, Samsung will sell the SD 820 variant of the S7 in China and the United States.

    Only yesterday, we caught wind of the Exynos 8890 -- also known as a the Exynos M1 -- clocking some mightily impressive scores in benchmark testing. Per this new report, the 8890 will be reserved for those in some European markets, Japan, and Samsung's native South Korea.

    Meanwhile the Exynos 7422, which once seemed certain to be the workhorse of the Galaxy Note5, could power the Indian version of the Galaxy S7.

    Speculations on the Rumors

    Exynos Roadmap:

    A rumored roadmap reportedly shows that Samsung will be using its own GPU on Exynos chipsets in 2017 or 2018. But before that happens, Samsung is supposed to employ Heterogeneous System Architecture (HSA) for its Exynos chipsets. With this architecture, the CPU and GPU are located on the same bus, allowing them to share the same tasks and memory. The bottom line is that a handset employing an HSA chip should run faster and offer improved graphics.

    According to the alleged roadmap, Samsung will debut an Exynos SoC with HSA in a year or two. The chipset will include a Mali GPU. Then, in 2017 or 2018, the Mali graphics processor will be replaced by a Samsung produced GPU that will be found in another new Exynos chipset. Back in September 2014, we passed along a rumor that Samsung was working on its own graphics chip. Since these things take time, it could be that the company is on schedule

    Samsung is said to be working on a new chipset, dubbed the M1, for its next generation of smartphones. We have seen a chip called the Exynos 8890 benchmarked on a device called Lucky-LTE, which just so happens to have specs similar to what we expect on the Samsung Galaxy S7. That would seem to indicate that the Exynos 8890 is the M1, and will be the new featured chipset on Samsung's high-end devices in certain regions. A report last week said that Samsung plans on using the Snapdragon 820 SoC on Galaxy S7 models headed for the U.S. and China, while the new Exynos chip would be found under the hood in the rest of the

    May 2015... The point is that Samsung's expanded use of their own Exynos SOC chips would be good for CRUS.

    It's increasingly hard for Samsung to keep data about its upcoming products from leaking onto the internet ahead of the official unveil. The latest leak from Samsung is claimed to be some new benchmarks of its upcoming SoC called Mongoose. Mongoose is said to be a new Exynos processor using a new CPU architecture.

    The Mongoose SoC is also known as the Exynos M1, which we have seen leaked benchmarks on before. The chip has custom CPU cores for improved performance and efficiency and could be the Exynos 8890 when it goes into production, but its real name remains to be seen.

    Recently an image turned up on Weibo claiming to show some benchmarks from the Mongoose processors. The benchmarks claim that a Mongoose running at 2.3 GHz scored 2294 points in single-thread test and 6,908 points in multi-thread testing.

    In power saving mode the chip racked up 1710 points in single-thread test and 4896 in multi-threaded tests. Running the same tests in ultra power saving mode scores 1100 in single and 3209 in multi thread tests via GeekBench. This isn't the first time that alleged benchmarks for these tests have leaked and there are improvements in this round of benchmarks indicating Samsung is improving the chip's performance. We still don’t know when the processor will launch inside a device consumers can purchase.

  • Northland Capital Markets maintains an Outperform rating on Cirrus Logic (NASDAQ: CRUS), with a price target of $44.00. After spending time with Cirrus, Northland feels a lot more positive. CRUS is benefiting from a number of market dynamics, and Northland believes that Cirrus should have ample opportunities for upside in the next 12-14 months.

    Northland analyst, Tom Sepenzis, commented on one of the key points, saying, "Samsung recently shifted its Galaxy S6/S6 Edge flagships to its own internally produced application processor and radio. Cirrus was the obvious winner with the smart-codec win, and we believe this will be the first of many such wins. Samsung is currently winning at the high end, with QCOM forced to throttle the performance of its 810 processor to deal with the overheating issues. It seems reasonable to assume that Samsung will look to further the use of its own processors and radios in multiple
    other platforms moving forward, and that heavily favors CRUS for the audio portion as QCOM will not be there to compete."

    IPhone 6S in Japan...

    by mk54321 Oct 5, 2015 8:33 PM
    mk54321 mk54321 Oct 5, 2015 8:44 PM Flag

    Apple has praised the iPhone 6s for selling a record-shattering 13 million units in its first three days. However, a new report suggests that in Japan the 6s and 6s Plus actually sold 10-15 percent fewer units than last year’s iPhone 6.

    How can both of these reported facts (record-breaking sales figures and lower demand) be true at the same time? There is an answer — and, no, it’s not Schrödinger’s iPhone.

    Provided that the figures by research firm BCN are accurate, one explanation could be that the iPhone 6s is disproportionately unpopular in Japan compared to other markets. I’d be inclined to doubt this, though, since Japan tends to be a strong market for the iPhone — with Apple’s handsets having accounted for an impressive 60 percent of Japan’s smartphone sales in 2014.

    Another possible explanation is put forward by carrier NTT DoCoMo. NTT DoCoMo says the iPhone 6s is selling well, although notes that it had fewer people queuing up for it on launch day. But this, the carrier says, could be due to the fact that — for the first time — stores have announced the date they’ll be receiving new iPhone inventory, possibly delaying some people making their purchases.

    The most obvious reason for why overall sales are up while demand could be down, however, relates to the markets which received the iPhone 6s on launch weekend.

    In 2014, China was not part of the iPhone 6 opening weekend due to regulatory problems. This year, both China and New Zealand joined the U.S., Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore and the United Kingdom as the first wave of markets to get the iPhone 6s.

    More people able to buy the iPhone = more sales, despite lower demand in individual markets.

    While this may be evidence that iPhone sales are finally starting to slow down, it’s still way too early to say for sure. After all, if Apple judged success or failure based on the first few days of a product’s availability, the Mac wouldn’t exist today.

  • Local carrier NTT DoCoMo insists iPhone 6s and 6s Plus sales are strong, but the popularity of Apple’s new devices and the number of people lining up outside stores suggests that demand is weaker than that for last year’s models.

    “However, NTT DoCoMo believes the weakening popularity may be because its stores have announced the dates that they may receive new inventory which therefore delayed some purchases,” reports DigiTimes.

    It should be noted, however, that these figures are based on research — not actual sales figures. Japan-based firm Nikkan Kogyo Shimbun is still optimistic about iPhone 6s and iPhone 6s Plus demand, and suggests we will see more accurate sales figures later this month.

    Qualcomm Snapdragon version #3 benchmark results

    the chipset scored 2032 in single-core, and 5910 in multi-core
    Still not as fast as Samsung's new Exynos 8890

  • How about an Exynos 8890 running at its purported 2.4 GHz maximums, though? Well, a renowned chipset leakster account over on Weibo has tipped the breathtaking results of such configuration - 2304 points on the single-threaded, and the whopping 8038 points on the multi-threaded Geekbench cross-platform test. To put these results in perspective, the Note5 with the latest Exynos 7420 is clocked at 2.1 GHz, and scored 1431 and 4717 points, respectively, when we ran Geekbench 3 on it.

    Rumor mill .....
    Galaxy S7 may be split between Qualcomm Snapdragon 820 and Samsung Exynos 8890.

    This is the what was done with the Galaxy S5 family..
    Exception was the Galaxy S6 family where all Exynos SOC were used since Qualcomm had heat issues with the Snapdragon 810.

    This has been lent further credence by another report from South Korea's Electronic Times (as reported by Reuters), but this report said that the Snapdragon 820 chip will only be used in Galaxy S7 handsets sold in China and the US. All other regions, on the other hand, will get one of Samsung's own Exynos processors.

    The present invention encompasses noise canceling techniques and circuits that can be implemented in a personal audio device, such as a wireless telephone. The personal audio device includes an adaptive noise canceling (ANC) circuit that measures the ambient acoustic environment and generates a signal that is injected in the speaker (or other transducer) output to cancel ambient acoustic events. A reference microphone is provided to measure the ambient acoustic environment and an error microphone is included for controlling the adaptation of the anti-noise signal to cancel the ambient audio sounds and for correcting for the electro-acoustic path from the output of the processing circuit through the transducer. However, under certain acoustic conditions, e.g., when a particular acoustic condition or event occurs, the ANC circuit may operate improperly or in an unstable/chaotic manner. The present invention provides mechanisms for preventing and/or minimizing the impact of such conditions.
