New device to catalyse faster data processing

December 23rd, 2011

A new optical device, tiny enough to fit millions on a computer chip, could catalyse faster, more powerful information processing and supercomputers.

The “passive optical diode” is made from two tiny silicon rings measuring 10 microns across, or about a 10th the width of human hair.

Unlike other optical diodes, it does not require external assistance to transmit signals and can be readily integrated into computer chips.

The diode is capable of “non-reciprocal transmission”, meaning it transmits signals in only one direction, making it capable of information processing, said Minghao Qi, associate professor of electrical and computer engineering at Purdue, the journal Science reports.

“This one-way transmission is the most fundamental part of a logic circuit, so our diodes open the door to optical information processing,” said Qi, working with a team also led by Andrew Weiner, Purdue professor of electrical and computer engineering, according to a statement.

Although fibre optic cables transmit staggering amounts of data across oceans and continents, information processing is slowed and the data are susceptible to cyber attack when optical signals must be translated into electronic signals for use in computers, and vice versa.

“This translation requires expensive equipment,” study co-author Jian Wang said. “What you’d rather be able to do is plug the fibre directly into computers with no translation needed, and then you get a lot of bandwidth and security.”

IOCELL NetDISK 351UNE Network Storage Device

November 29th, 2011

The first thing that IOCELL Networks wants you to know about the NetDISK 351UNE is that it is not a NAS; instead it is a network-direct-attached-storage (NDAS) device. It does not function as a server, and there are some distinct benefits that come with that. For one: size, cost and complexity go way down. Two: it does not use TCP/IP to connect to your network, which eliminates all common TCP/IP-based methods for hacking into your data. Three: it’s faster, since there is so much less overhead to manage. Sometimes, less is more. Benchmark Reviews has looked at several full-range NAS products in the last few months, now let’s investigate what a more tightly focused approach can provide.

The NetDISK 351UNE uses a proprietary Lean Packet Exchange (LPX) protocol to transfer data to and from your network, and this protocol is contained in a driver package that must be loaded on each computer that desires access to the data store. Before you balk at that, it’s the same with printers, scanners, or any other peripheral device on your network, so don’t despair. There are advantages, such as the fact that no one is likely to hack into your LPX device. I’ll take that over troubles with DHCP settings, any day.

The IOCELL NetDISK 351UNE is the first logical step up from an ordinary direct-attached-storage device. Hooking an external drive up to your PC with USB 3.0 or eSATA makes that storage available on the PC it’s connected to, and it can also be accessed by other computers on the network through drive sharing. The downside is that the target PC may not always be turned on, or if it’s a laptop, it may not even be in the building. Also, folder sharing is still a little cumbersome, and introduces security risks. If you’re worried about hidden malware on your own PC, just imagine the number and the types of threats that are contained on the typical teenager’s laptop.

The 351UNE is one of the lowest cost storage units on the market to offer a full complement of interfaces – Ethernet, eSATA, and USB. The unit I tested came without a drive, and there are also units available with 1TB and 2TB drives installed at the factory. I like the ability to choose the brand and type of HDD that contains my data, so this unit is the one I would most likely purchase.

Three features dominate the discussion of network storage hardware: data capacity, data security, and data transfer speed. The current crop of NAS devices offer a dizzying array of applications to help manage and distribute the data, and provide several new ways of accessing that data. The 351UNE is content to live a simpler life, serving up files and folders with a stripped down interface that looks and acts just like a local drive. As such, it focuses intently on those three critical features: capacity, security and speed. Going back to basics also caps the cost as well, which always an advantage.

Benchmark Reviews wants to believe that smaller, faster and cheaper is better, but we remain skeptics at heart. Let’s dig in and carry out a full review of this new class of network storage products, and see how it compares to more traditional solutions.

5 Ways to Get TV on Your Mobile Device

November 7th, 2011

With the creation of award-winning and compelling content on premium cable networks like HBO, Showtime, AMC, FX, and more, TV is quickly becoming the place to watch truly compelling entertainment that pushes the medium forward. At the same time that TV is getting better, technology is making it easier to access media wherever and whenever we want to. However, being able to access free TV on your mobile devices is still a hassle and virtually impossible.

Although we’re used to being able to sit down and watch TV shows for free on services like Hulu as well as a number of network websites, finding free TV in a mobile environment is a headache. It seems that every mobile TV platform is a paid service. And in this economy, not everyone has the extra money to shell out on monthly cable/satellite service or pay premium fees for specialized services.

But if you’re looking for a way to gain mobile access to your favorite shows, here is a rundown of some of the most popular streaming media options, despite their various costs.

1)Hulu Plus: Although you can watch plenty of TV shows and movies for free through Hulu on your computer, in order to watch it on your mobile device, you’ll have to pay. The Hulu+ app for your smartphone is $7.99/month and gives you access to all the premium content on Hulu+, not just the free stuff.

2) iTunes: There are thousands of movies and TV shows available on iTunes. However iTunes doesn’t have a subscription service, you have to buy (or rent) each episode, season, or movie individually. On the plus side, once you’ve bought and downloaded anything, it is yours to keep forever and you can play it without having to be connected to the internet.

3) Netflix: Netflix also has a huge streaming library of TV and movies, and you can download the app for free when you sign up for the service (starting at about $10/month). It’s a lot like Hulu+, only more focused on movies rather than TV shows.

4) Cable/Satellite providers: Not to be left behind in the digital revolution, many of the top cable and internet providers, like DISH and Comcast (Xfinity), now offer apps for watching premium content through your mobile device when you sign up for service. Pricing will vary according to your package and services, but you can end up paying over $100/month for one of these plans.

5) OrbLive and Slingbox: Others apps like OrbLive and Slingbox let you remotely access music, movies, and TV shows you have stored on your home computer. However, not only do you have to buy the app and the hardware ($100-$350), then you have to do all your own setup and may have to buy even more hardware in order to watch live TV. So, unless you’re very tech-savvy to begin with, this is probably not a good option.

Besides these options, you can download apps from ABC and CBS that offer you free access to their shows, but unless you’re a really big fan of CSI or The Bachelorette, this is very limiting.

In the end, if you want access to a wide variety of streaming content on your mobile device, you’ll need to pay. In order to decide which option is best for you, you’ll have to decide what kind of content you want access to and how much you are willing to pay. For those that want current TV episodes from the major networks, Hulu+ might be best. But if you want immediate access to a spate of HBO shows, maybe it’s better to go through your cable/satellite provider. Or if what you really want is movies, go for Netflix.

Pebble bay on the pulse of device driver development

October 6th, 2010

Embedded systems development consultants Pebble Bay has announced that it has been working with medical device manufacturer LiDCO Ltd, a leading supplier of minimally invasive haemodynamic monitoring equipment. Pebble Bay has provided software development services, enabling an updated version of the LiDCOrapid product to use a wider choice of card readers.

LiDCO makes a range of products that use a novel, non-invasive technique to measure the flow of blood from the heart. The LiDCOrapid product is based on PC-compatible hardware running the QNX Neutrino real-time operating system.

The previous version of the LiDCOrapid monitor was controlled by a smart card via a serial link. In the new version, LiDCO have moved to a new USB-interfaced card reader, taking the opportunity to adopt a standard protocol and software component to provide the interface to the card readers, therefore abstracting the system and application software from specific details of the card reader interface.

LiDCO chose to adopt the Personal Computer/Smart Card specification (www.pcscworkgroup.com), and needed to port the existing PC/SC-Lite Linux implementation to the QNX Neutrino operating system to support their application.

Although they have the required expertise in house, LiDCO chose Pebble Bay for this project so that their staff could focus on development of the application software.

“We initially carried out a short consultancy project to investigate the technical aspects of porting the existing PC/SC-Lite software stack, including support for USB-connected smart cards, to the QNX Neutrino 6.x real-time operating system,” said Ian Willat, Managing Director of Pebble Bay.

“During this consultancy, we determined what we believe to be the best approach to carrying out the port, bearing in mind LiDCO’s requirements, the technical differences between Linux and QNX Neutrino, the likely amount of effort involved in carrying out the port, and any risks we have identified. We then documented the results of this consultancy in a technical report.”

Pebble Bay then carried out the port of PC/SC-Lite and the other required software components to QNX Neutrino for LiDCO. The project included testing the ported software at its site, followed by delivery and acceptance at LiDCO’s office in London.

“We found Pebble Bay to be very easy to work with, and their project management kept things running smoothly throughout the engagement. Pebble Bay’s expertise in working with USB, device drivers and real-time operating systems meant that we were in safe hands, which was demonstrated by the ease with which our application software integrated with the ported PC/SC-Lite they delivered.”

As a result of Pebble Bay’s device driver development work, LiDCO’s system can now support a wider choice of card readers, with little or no change to the application software. In addition to this, with LiDCO and Pebble Bay working in parallel, it meant that development time was minimized and alongside Pebble Bay’s previous experience in working with USB device drivers, allowed them to identify and mitigate the risks associated with the port early in the project.

“I am very pleased to report that this project ran very smoothly,” stated Ian Willats. “There were some technical challenges associated with the way the USB bus was enumerated and the devices configured. However, our in-depth expertise of USB protocols and device drivers allowed us to solve these quickly and without slowing down the project.”

Motorola to ship tegra powered devices soon?

September 26th, 2010

There is a seemingly endless number of hardware manufacturers currently in the mobile industry. Not only are there laptop manufacturers but they are smartphone manufacturers and more recently, tablet manufacturers (among other industries). While the classifications remain somewhat constant, hardware from device to device changes dramatically.

It wasn’t until recently that smart phones became more similar to a handheld computer than a traditional cell phone. Some may argue that this is solely because of the advanced mobile operating systems powering these devices. However, without beefy hardware under the hood, those advanced mobile operating systems wouldn’t run as gloriously as they do on some of today’s higher end devices.

This beefy hardware can be found in pretty much any modern device running a so called advanced mobile operating system. For instance, Apple’s iPhone 4 running iOS features a 1GHz processor and 512MB of RAM. Android powered devices too like the HTC EVO 4G and Samsung Galaxy S feature similar specs.

As of late, the hardware in these devices has generally plateaued with just about every handset being released with virtually identical specs. Luckily, companies have said in the past that they hope to do away with this plateau with Motorola even going as far as saying they hope to release a 2GHz device by year’s end.

Well today, it seems that some new reports have been uncovered that say Motorola didn’t exactly mean a 2GHz processor but instead NVIDIA’s dual-core 1GHz Tegra processor. But wait, Motorola utilizing NVIDIA hardware when they’ve been using Texas Instruments chips ever since the original Droid?

According to NVIDIA CEO Jen-Hsun Huang, yes, Motorola will begin shipping devices with NVIDIA’s Tegra 2 mobile processor. Huang elaborates by saying that he believes Motorola will eventually become one of NVIDIA’s biggest customers in the handset world.
While there has been a lot of talk about NVIDIA’s Tegra 2 processor, it has yet to hit the market. Perhaps Motorola will be one of the first with a Tegra 2 powered device? We’ll have to wait and see.
