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.
HP Aims To Boot ‘Useless’ Data
Hewlett-Packard wants to help organizations rid themselves of useless data, all the information that is no longer necessary, yet still occupies expensive space on storage servers.
The company’s Autonomy unit has released a new module, called Autonomy Legacy Data Cleanup, that can delete data automatically based on the material’s age and other factors, according to Joe Garber, who is the Autonomy vice president of information governance.
Hewlett-Packard announced the new software, along with a number of other updates and new services, at its HP Discover conference, being held this week in Las Vegas.
For this year’s conference, HP will focus on “products, strategies and solutions that allow our customers to take command of their data that has value, and monetize that information,” said Saar Gillai, HP’s senior vice president and general manager for the converged cloud.
The company is pitching Autonomy Legacy Data Cleanup for eliminating no-longer-relevant data in old SharePoint sites and in e-mail repositories. The software requires the new version of Autonomy’s policy engine, ControlPoint 4.0.
HP Autonomy Legacy Data Cleanup evaluates whether to delete a file based on several factors, Garber said. One factor is the age of the material. If an organization has an information governance policy of only keeping data for seven years, for example, the software will delete any data older than seven years. It will root out and delete duplicate data. Some data is not worth saving, such as system files. Those can be deleted as well. It can also consider how much the data is being accessed by employees: Less consulted data is more suitable for deletion.
Administrators can set other controls as well. If used in conjunction with the indexing and categorization capabilities in Autonomy’s Idol data analysis platform, the new software can eliminate clusters of data on a specific topic. “You apply policies to broad swaths of data based on some conceptual analysis you are able to do on the back end,” Garber said.
New Chip To Cut Cost Of LTE Smartphones

Comments Off on New Chip To Cut Cost Of LTE Smartphones
Chip manufacturer Renesas Mobile has unveiled the MP5232, a processor that will allow vendors to build LTE (Long Term Evolution)smartphones with a price tag between $150 and $300, the company said Wednesday.
The big advantage of the 1.5GHz dual-core processor is that it is a single-chip product that can do both 3G and LTE, eliminating the need to use separate chipsets for the two technologies. A more integrated device results in a cheaper product that takes up less space and uses less power, according to Malik Saadi, principal analyst at Informa Telecoms and Media.
The cost is important, because for LTE to take off, there is a need for smartphones that cost less than current products, according to Renesas.
In addition to smartphones, the MP5232 can also be used to power tablets, said Renesas.
One of the challenges of developing chipsets for LTE is the plethora of frequencies used. Renesas hasn’t specified which bands the MP5232 can handle, but says it is designed to support all major operators and their respective requirements.
Data Center Emissions Concerns Citizens
Comments Off on Data Center Emissions Concerns Citizens
Some residents of Quincy, Washington, the location of massive data centers operated by Microsoft, Yahoo and others, are growing concerned about pollution from backup diesel generators at the data centers, and on Wednesday they’ll have the chance to discuss the issue.
The Washington State Department of Ecology is conducting a public meeting on Wednesday evening in Quincy for residents to voice their concerns over on an application from Dell for permission to use 28 generators powered by diesel engines.
Quincy, a town of around 6,000 people, will have 141 back-up generators once those belonging to Dell, and others that have been permitted or are in line for permission, are put in place. While the generators are designed to be used only in the rare case of an electricity outage, the data center operators turn them on regularly for testing.
On average, the companies are permitted to turn on each generator for 103 hours per year. If they use that maximum running time, data center generators in Quincy would run for the equivalent of 40 hours per day on average.
The Department of Ecology says diesel emissions, when breathed in, have been known to create or worsen a variety of health problems, including heart disease, asthma and
lung cancer.
Some residents, including former mayor Patty Martin, wonder about the health impact of the diesel emissions on the community. She thinks the generators should use the same types of devices to reduce emissions that are required by other Washington cities such as Olympia and Moses Lake.
Such devices aren’t necessary in Quincy, said Karen Wood, section supervisor for air quality in Eastern Washington for the Department of Ecology. Because Olympia is a much bigger city it already has high diesel emissions from other sources, so a new data center there was required to reduce its emissions, she said.
