Samsung’s Eight-core Chip Goes Hacking
Comments Off on Samsung’s Eight-core Chip Goes Hacking
A Samsung eight-core chip used in some Galaxy S4 mobile devices is now available for hackers to play with on a developer board from South Korea-based Hardkernel.
Hardkernel’s Odroid XU board has incorporated Samsung’s eight-core Exynos 5 Octa 5410 chip, which is based on ARM’s latest processor designs. Samsung recently announced a new eight-core chip, the Exynos 5 Octa 5420, which packs faster graphics and application processing than the 5410. The 5420 has not yet been shipped yet, however.
The Odroid board is priced at $149 through Aug. 31, after which it will be offered for $169. Samsung for many months has said that a board with an eight-core chip would be released, and has shown prototype developer boards at conferences.
Odroid-XU will provide developers an opportunity to write programs tuned for Samsung’s octa-core chip, which has been a source of controversy. Analysts have said the eight-core design is overkill for small devices like smartphones and tablets, which need long battery life.
The eight-core chip design also takes up a lot of space, which prevented Samsung from putting LTE radios inside some Galaxy S4 models. Qualcomm, which hesitantly moved from the dual core to the quad-core design on its Snapdragon chips, on Friday criticized eight-core chips, calling the idea “dumb.”
Despite the criticism, the board will give developers a first true glimpse of, and an opportunity to write and test applications for, ARM’s Big.Little design. The design combines high-power cores for demanding applications with low-power cores for mundane tasks like texting and calling.
Samsung’s iteration of Big.Little in the Exynos 5 Octa 5410 chip combines four processors based on ARM’s latest Cortex-A15 processor design, which incorporates four low-power Cortex-A7 CPUs. The Cortex-A15 is ARM’s latest processor design and succeeds the previous Cortex-A9 core, which was used in popular smartphones like Apple’s iPhone and the Galaxy S3. Samsung said the eight-core chip provides a balance of power and performance, with the high-power cores kicking in only when necessary.
The board has an Imagination Technologies PowerVR SGX544MP3 graphics processor, 2GB of low-power DDR3 DRAM, two USB 3.0 ports and four USB 2.0 ports. Other features include Wi-Fi, Ethernet and optional Bluetooth. Google’s Android 4.2 operating system is preloaded, and support for other Linux distributions like Ubuntu is expected soon. The board has already been benchmarked on Ubuntu 13.04.

According to a report over at Tabtech.de that managed to spot an unknown device in the result page of the GFXBench, Nvidia might be gearing up to release a phablet or tablet.
The device is listed as Nvidia Tegra Note Premium and scores just slightly lower than the Nvidia Shield in GFXBench. It feature Tegra 4 clocked at 1.8GHz and has a resolution of 1280×800 which probably points out to a tablet rather than phablet but everything is possible. It was running Android 4.2.2 Jelly Bean when it was tested.
At Computex 2013 back in June, Nvidia showcased a rather unique device that was used to demonstrate pressure-sensitive functions of a stylus and which might be the device that showed up in the GFXBench results. The 1280×800 resolution is not impressive and far off from what the competition currently has to offer, but then again Nvidia might want a cheaper tablet or phablet on the market.
In any case we will surely keep an eye out for Nvidia’s Tegra Note Premium, whatever it turns out to be.
Intel Launches 530 Series SSD
Intel’s new SSD 530 series was detailed a while ago, but now it is finally official. Intel has formally announced the new drives in three form factors: mSATA, M.2 and 2.5-inch.
The drives will be available in a wide range of capacities, starting at 80GB, through 120GB, 180GB, 240GB, 360GB and 480GB for 2.5-inch drives. As for M.2 and mSATA drives, they will be available in 80GB, 120GB, 180GB and 360GB capacities.
Intel’s new 530 drives are based on 20nm MLC flash and the brains behind the brawn come from LSI, in the form of the SandForce SF-2281 controller. Although transfer speeds will vary depending on capacity, the fastest 530-series drives will deliver read speeds of up to 540MB/s and write at 490MB/s. As for random performance, they boast 41k IOPS in random read and 80k IOPS in random write.
Intel also says the 530-series is its most power efficient storage product to date, which is hardly surprising, but it is good news for notebook vendors who will use mSATA units.

Comments Off on WiLan Loses In Court
Wi-Lan has suffered defeat in its patents trial against Alcatel Lucent, Ericsson, HTC and Sony, as a Texas court decided that the firms did not infringe its patents.
Wi-Lan filed a lawsuit against Alcatel Lucent, Ericsson, HTC and Sony in 2010 claiming the firms infringed patents that relate to data transmission over wireless networks. However a Texas court ruled that the four firms did not infringe Wi-Lan’s patents and found one patent Wi-Lan asserted against HTC and two it asserted against Alcatel Lucent invalid.
Wi-Lan had asserted that Alcatel Lucent and Ericsson infringed three patents, none of which claims were upheld by the court. The firm also asserted that HTC and Sony infringed another patent, and there the court not only judged against infringement but invalidated the patent.
Alcatel Lucent and HTC both said that Wi-Lan was trying to stretch its patents to cover technology in their devices.
Sally Julien, a spokeswoman for HTC said, “HTC believes that Wi-Lan has exaggerated the scope of its patent in order to extract unwarranted licensing royalties from entities who have been focused on bringing innovation forward in their own products.”
Kurt Steinert, an Alcatel Lucent spokesman said, “We think this validates our belief that Wi-Lan was stretching the boundaries of its patents, and the jury confirmed that belief.”
Wi-Lan has managed to get several companies to license its technology including Dell and Panasonic, and in May it initiated legal proceedings against Blackberry over a patent relating to Long Term Evolution network technology. However in this case the firm did not prevail against two large telecom equipment companies and two big smartphone makers.
Xen Project To Support ARMv8
Xen Project will release the Xen 4.3 hypervisor later today with support for ARMv7 and ARMv8 hardware.
The Xen Project overseen by The Linux Foundation produces an open source hypervisor that is a popular alternative to KVM. The project will release the Xen 4.3 hypervisor today with support for ARM servers, performance improvements and a technology preview of Open Vswitch.
The Xen Project is backed by a number of big firms including AMD, Cisco, Google, Intel and Samsung, and is one of the first hypervisors to support ARMv8 based processors along with the ARMv7 architecture. The Xen Project said it has been working with ARM server vendor Calxeda to validate Xen 4.3 on its ARMv7 and ARMv8 servers.
For the Xen Project, ARM server support, in particular ARMv8 support, will be key as servers using the architecture start to appear later this year and in volume during 2014. Given that Amazon Web Services, arguably the biggest cloud service provider around, is supporting the Xen Project, ARMv8 support in the hypervisor could be painful for VMware as it tries to compete against a free, industry supported alternative.
Lars Kurth, community manager for the Xen Project said, “The ARM server support is an exciting development for the community and we’re excited about the opportunities this will bring to customers.”
Xen 4.3 also includes improvements to power efficiency by using the MWAIT extension for processors such as Intel’s Sandy Bridge, Ivy Bridge and Haswell.
Linux Foundation VP and COO Mike Woster talked up the importance of virtualisation to the Linux and open source community. He said, “Virtualization is important to Linux and the open source community and the Xen Project is helping companies realize new levels of scalability and efficiency in areas such as cloud computing.
“With the latest release of Xen Project, organizations can advance their cloud computing strategies to deliver on customer expectations for their enterprise environments.”
The Xen 4.3 hypervisor was released yesterday.
Intel Invests In Tablet Business
Intel has invested in E La Carte, a firm that designs tablets for restaurants.
Intel Capital, the chipmaker’s investment arm, has bought into in all sorts of companies outside of semiconductors in a bid to diversify the firm’s income. Now the chipmaker has invested in E La Carte, a firm that designs tablets for use in restaurants.
E La Carte raised a total of $13.5m in second round funding for its niche tablet business, with Intel Capital leading the investment. The firm said it would use the capital injection to grow the firm and to try to increase the number of restaurants that use its tablets.
Christine Herron, director of Intel Capital said, “E La Carte offers the most innovative and reliable guest tablet solution in the industry. We’re thrilled to further accelerate the company’s growth with not only capital, but also our significant resources and expertise in manufacturing, operations, and media.
“As E La Carte transforms the dining experience, we are creating a new market for both restaurant and guest services.”
E La Carte claims to have sold thousands of tablets to restaurants and cites a month on month growth rate of 35 percent. For Intel it is one way of getting a foothold in the tablet market, even if its Clovertrail+ tablets have yet to take the market by storm.
Rajat Suri, CEO of E La Carte said, “We are excited to work with Intel to grow our footprint to more restaurants across the country. With more than 200,000 casual-dining restaurants in the US, we see an enormous opportunity to make full service and fast casual restaurant experiences more enjoyable for guests, and more profitable for restaurant operators.”
Aside from the cash, Intel Capital will also provide advice in manufacturing, operations and media to E La Carte, presumably with the hope of taking the firm public in the future.
CPU-Z Hits Android
Popular hardware identification tool CPU-Z has hit the Google Play Store. Like the PC version, the apps is completely free and it offers tons of information about your device.
It identified the SoC on board, along with the architecture and clock speed for each core. It also figures out the exact device brand, amount of RAM, storage, battery level, status and temperature. It can tap into the device’s sensor array, which is more of a gimmick than anything useful.
It’s worth noting that it is still in beta, so there might be some kinks to work out. If you’re eager to give it a go, you can find it here. https://play.google.com/store/apps/details?id=com.cpuid.cpu_z.
nVidia’s CUDA 5.5 Available
Nvidia has made its CUDA 5.5 release candidate supporting ARM based processors available for download.
Nvidia has been aggressively pushing its CUDA programming language as a way for developers to exploit the floating point performance of its GPUs. Now the firm has announced the availability of a CUDA 5.5 release candidate, the first version of the language that supports ARM based processors.
Aside from ARM support, Nvidia has improved supported Hyper-Q support and now allows developers to have MPI workload prioritisation. The firm also touted improved performance analysis and improved performance for cross-compilation on x86 processors.
Ian Buck, GM of GPU Computing Software at Nvidia said, “Since developers started using CUDA in 2006, successive generations of better, exponentially faster CUDA GPUs have dramatically boosted the performance of applications on x86-based systems. With support for ARM, the new CUDA release gives developers tremendous flexibility to quickly and easily add GPU acceleration to applications on the broadest range of next-generation HPC platforms.”
Nvidia’s support for ARM processors in CUDA 5.5 is an indication that it will release CUDA enabled Tegra processors in the near future. However outside of the firm’s own Tegra processors, CUDA support is largely useless, as almost all other chip designers have chosen OpenCL as the programming language for their GPUs.
Nvidia did not say when it will release CUDA 5.5, but in the meantime the firm’s release candidate supports Windows, Mac OS X and just about every major Linux distribution.
Dell Promises ExaScale By 2015
Dell has claimed it will make exascale computing available by 2015, as the firm enters the high performance computing (HPC) market.
Speaking at the firm’s Enterprise Forum in San Jose, Sam Greenblatt, chief architect of Dell’s Enterprise Solutions Group, said the firm will have exascale systems by 2015, ahead of rival vendors. However, he added that development will not be boosted by a doubling in processor performance, saying Moore’s Law is no longer valid and is actually presenting a barrier for vendors.
“It’s not doubling every two years any more, it has flattened out significantly,” he said. According to Greenblatt, the only way firms can achieve exascale computing is through clustering. “We have to design servers that can actually get us to exascale. The only way you can do it is to use a form of clustering, which is getting multiple parallel processes going,” he said.
Not only did Greenblatt warn that hardware will have to be packaged differently to reach exascale performance, he said that programmers will also need to change. “This is going to be an area that’s really great, but the problem is you never programmed for this area, you programmed to that old Von Neumann machine.”
According to Greenblatt, shifting of data will also be cut down, a move that he said will lead to network latency being less of a performance issue.”Things are going to change very dramatically, your data is going to get bigger, processing power is going to get bigger and network latency is going to start to diminish, because we can’t move all this [data] through the pipe,” he said.
Greenblatt’s reference to data being closer to the processor is a nod to the increasing volume of data that is being handled. While HPC networking firms such as Mellanox and Emulex are increasing bandwidths on their respective switch gear, bandwidth increases are being outpaced by the growth in the size of datasets used by firms deploying analytics workloads or academic research.
That Dell is projecting 2015 for the arrival of exascale clusters is at least a few years sooner than firms such as Intel, Cray and HP, all of which have put a “by 2020″ timeframe on the challenge. However what Greenblatt did not mention is the projected power efficiency of Dell’s 2015 exascale cluster, something that will be critical to its usability.
Will Qualcomm Be First?
We could not get the right timeframe for the launch of Qualcomm’s successor to the high-end Snapdragon 800, but there is no doubt that Qualcomm, Samsung, Nvidia and other ARM supporters are thinking about 20nm products where some of them will be based on Cortex A57.
Qualcomm has its own Krait core that can be adapted to 20nm and follow up the success of Snapdragon 600 and the soon to come Snapdragon 800. It turns out that it traditionally takes 18 to 24 months for the mobile industry to shift from one process to another and Qualcomm had its first 28nm part in April 2012, with the Snapdragon S4, used in the HTC One S. The first ever 28nm part from Qualcomm was the Snapdragon S4 MSM8260A that is now more than a year old and a relatively obsolete product.
Less than a year after the first 28nm product Qualcomm followed up with the Snapdragon 600 that is shipping in millions of high end devices right now. In a month or two it plans to release Snapdragon 800 based on new Krait 400 core and add a new core and get even better performance.
The next step is the 20nm core that should start shipping before the end of 1H 2014. We would not be surprised to see 20nm Krait demoed at CES 2014 already in January, see more of it at the Mobile World Congress in February and the volume shipment to follow in early Q2 2014. This is the expected schedule and not something we got from Qualcomm.
The only official world we got is that the new generation traditionally comes 18 to 24 months after the first iteration of a current one. This can give you an idea that Tegra 5, codenamed Logan, should show up at a similar time, along with Samsung’s 20nm Exynos.
