High Dynamic Range Computing

Posted on 23 April 2011, Last updated on 10 August 2013 by

There are two very popular and very different Internet  viewpoints out there.  One shows social, app-centric, dynamic, location-aware mobile environments and the other looks out on high quality, feature rich work environments. [More on the two Internets and Web experiences here] Computing hardware platforms have crossed over from both sides but there’s still a problem getting apps across the bridge between the hand to the desktop. This article, adapted from a presentation given at Mobile Monday, briefly highlights how a new OS could be the bridge that enables high dynamic range computing, HDR Computing.

The presentation is available online.

You Only Have One Time-Line

You have one timeline of activities and at certain points, they mix and crossover. There’s little chance in the modern life to separate the two works of work and home and as a result, the need for applications, documents and content to be synchronized across different devices is greater than ever.  The phone becomes the pivot point for the data but that data needs to extend across an increasing number of devices. Devices and applications tend to stitck to both work and play timelines making them inseparable.

Why we need multiple devices

What you can do within 3.5″ 11 inch is limited in terms of screen and computing thermals, input mechanisms and battery life. Smaller devices are becoming  more capable but physics gets in the way of complete convergence.

This shouldn’t be a surprise to anyone. For example, to write this document, I had to sit down, use a 10 inch screen and a touch-typable keyboard. As I type this, my tablet is next to me.

Why is my tablet next to me?  Because it does some things better than my laptop and some things that my laptop just can’t even attempt to do. SMS, WordPress notifications, Gtalk, Twitter are all examples and they work better because of always-on, applications and hardware like sensors and camera. Plus, PCs tend to run wild and uncontrolled when there are multiple apps running. That reduces battery life for critical work-related processes. The continuity between my two devices is split. Each device has a limited dynamic range in terms of software and hardware capabilities. It would be nice to have a single device that offers the best of both worlds but based on physical issues mentioned above, it’s not possible but what if there was an operating system, a hardware platform and an applications library that could span different usage models? The useful range of any device would be extended into an HDR device.

There are no options today.

A PC can’t idle down to 200mw power drain and enable always-on capability. Most PCs and desktop software don’t support location. You can find PC apps but they are big and often do too much resulting in expensive software products. They often take 10 minutes or more to dowlnoad and install which limits the try-then-buy(and recommend) model.
On the other hand, ARM CPUs that many tablets and nearly all phones are based on don’t have the CPU power to enable advanced processes. Video editing for example. Mobile operating systems also offer relatively shallow apps. Take a look at the office suites out there for mobile operating systems. The free MS Office Starter solution on a PC is stunning by comparison. Multi-user logins, multiple on-screen apps, drag and drop, encryption, USB host, rollback, remote desktop, VPN support, networks drives and many other features are either poorly implemented or just don’t exist on mobile operting systems.

Hardware is crossing over.

While it’s not possible to get hardware that spans mobile and table-top computing scenarios today, it may be possible very soon. Here are some examples of what’s happening in the hardware market.

  • The camera in my Nokia N8 has a better quality sensor than my 3 year old bridge camera
  • ARM CPUs are reaching the processing power of low-end X86 platforms
  • X86 platforms are reaching the idle battery drain of the high-end ARM platforms
  • You can run Android on X86 and, Ubuntu on ARM
  • The screen, storage, radio, battery, cooling, and production technology and processes are the same for both platforms.

Mobile operating systems are pushing into desktop form factors.

Add new Operating Systems to enable HDR-Computing

Both mobile and desktop operating systems today were written for one target segment and then, in order to explore new markets expanded from there. This strategy tends to result in compromises as desktop features are bolted on to mobile operating systems and mature desktop operating systems suffer from ‘bloat’ and legacy hardware support. An operating system built for HDR Computing has to be built from the ground up for its intended purpose. To span multiple hardware platforms, offering a ‘best of’ feature set that can enable both mobile and desktop operating modes through application cores that re-skin based on that operating mode, screen size and input method.

RED FLAG

Companies that sell products in laptop, desktop and mobile markets will NOT want to collapse their ecosystems into one. Separation helps multiple sales.

GREEN Flags

There are clear opportunities. Some are very heavyweight.

  • HDR Computing is disruptive
  • HDR Computing could enable a migration to cheaper, quicker product manufacturing, reduced support costs.
  • HDR Computing enables something that Joshua Topolsky was talking about recently – Continuous Client.
  • HDR Computing enables Single chassis, multiple bodies (Cost, time savings for OEDs)
  • HDR Computing has obvious developer advantages. (One core, multiple uers interfaces,multiple markets)

Not just for Mobiles and Desktops.

There are multiple markets where HDR Computing could extend.

  • Cars. When one platform / OS is approved, it can be used with multiple skins, features, options.
  • Cameras. Digital cameras are about to go through a big change via Internet sharing
  • TVs. A huge market.
  • Gaming devices. A huge market.
  • Vertical markets – Hospitals, Blue Light sector (one security approval – many devices)

There are Barriers – and they are Expensive

HDR Computing is not easy and platforms, operating systems and applications will take years to mature. Major hurdles exist.

  • Traction. It’s a huge leap that will require massive investment in marketing and market confidence.
  • Silicon engineering and thermals. We can just about reach notebook processing power for short periods of work in a handheld device. Controlled platform is key. Modular systems also solve the problem. (High power when docked for example)
  • Applications – Who wants to write applications for a fledgling operating system?
  • One-size doesn’t fit all? Often, single-use devices with dedicated operating systems and applications are better.

Who has an Opportunity?

There are some obvious players in the market that could take on HDR Computing. As mentioned above, HDR Computing is a Red Flag for companies that make profits in multiple mobile and desktop markets.

  • HTC – Mobile only
  • Intel – Sell HDR silicon.
  • Google – Successful in mobile devices only at present. Looking to expand.
  • Nokia – Mobile only although their ‘distruptive computing’ group might find themselves with a lower budget / BG this year.
  • A very, very big startup!

Obviously companies with large cash reserves also have an opportunity. Samsung and Apple come to mind immediately but their opportunity to be distruptive is limited due to their existing revenue streams on multiple different operating systems. ARM is a company that sells licenses but could gain from creating a sister company (or partnering, being taken over or taking on another company) that creates products. To compete with their own licensees would be a complex and risky business strategy however.

What’s happening today?

Five operating systems to watch are:

  • Ubuntu
  • MeeGo
  • Honeycomb branch of Android
  • Windows 8
  • WebOS

All of the above operating systems have an opportunity to become an HDR operating system. There is also work going on in other areas.

  • Componentised apps (multiple UIs, one core) already exist in iOS and Android
  • ARM Cortex A15 quad-core hardware – Above netbook processing power, below netbook idle usage.
  • Intel Atom – Moorestown, Medfield idle into ‘near zero’ remove PC history, power up to above netbook processing power. Turbo, thermal controls.
  • AMD – APU work. GPU, HD decoding, GPGPU support. Small die. (Still old PC compatability though)
  • Apps. Honeycomb signals start for serious Android app developement.
  • IOS Serious app development ‘trust’ is already there.
  • MeeGo App store.
  • WebOS? QNX? Lets wait and see.
  • CUPP Computing – innovative approach using dual CPUs in one system (can support multiple concurrent OS)
  • Hardware Virtualisation

What about HTML5?

It’s another opportunity. But is it too removed from hardware and multiple types of browser may stall the process. Energy and speed efficiency gets harder, the further it is removed from the hardware.

The cloud isn’t mobile yet.

Summary.

HDR Computing is a major opportunity. It proves that the mobile and desktop markets for hardware, operating systems and applications are not as safe and stable as many might think and could be turned on their head. It could simplify the process for manufacturers, consumers and applications developers and enable the idea of  ‘continuous client’ through easier state synchronization. It requires a new style of hybrid silicon platform that can idle at very low power levels but when required, can produce desktop-level processing levels. These new platforms will be very tightly coupled to an operating system and possibly developed in unison. There are opportunities for new players but the costs and timescales are prohibitive for all but the largest and best-positioned companies.
