Minimum Spec for MeeGo 1.2+ devices confirmed

November 16, 2010 31 comments

 

If there were any fears that Nokia’s upcoming MeeGo devices would have specs in keeping with current S^3 devices, we can all breathe  a somewhat collective sigh of relief.
Recent tweets and announcements from the MeeGo conference follow on twitter here minimum specs have been confirmed to be a minimum of 512MB RAM, 600MHz+ Arm V7 or x86 processors (Snapdragon, A4, OMAP,ST  U8500 all fall into this category) 512 Mb internal ROM and GSM/HSPA. Unfortunately for those living in certain regions, CDMA is looking unlikely to be supported until version 1.3. In addition, the official releases for 1.1 and 1.2 DO NOT include support for LTE (bummer 😦 ).

Update: MeeGo 1.3 is looking at an October 2011 release, soooooooooooooooo far away

I’ll try to keep you all posted on anything coming out of the conference.

Update 2

MeeGo 1.2 is expected to be released in April 2011 in keeping with the 6 month cadence between release versions. Should be noted yet again that these releases are not directed towards the end-user.

Action items for MeeGo 1.2 include increased QML use in applications, an integrated backup-restore mechanism, Office document viewers integrated with OS, better package managers and security features.

NB, Office viewers are currently being done by separate developers, see KOffice for MeeGo tablet.

Update 3

Twitter is reporting that screen res requirements haven’t been decided upon. Of big importance this bit. Aspect ratios matter a lot when writing apps (at least for beginners 🙂 ) careful consideration should be given to the available chipsets, display technology and touchscreen controllers. The latter being very very important for running touch-controlled interfaces. Terrible idea to match 720p or XGA screens with sub XGA controllers. VERY VERY bad.

Video: ST Ericsson U8500 1.2GHz Dual Core ARM Cortex A9 with MeeGo Phone OS

November 13, 2010 14 comments

A couple of days ago  MyNokiaBlog.com reader, Marcin, mentioned the ST Ericsson U8500 for MeeGo

“ST-Ericsson U8500 Linaro and MeeGo 11.30 -12.10, November 16th, 2010 MeeGo Convergence Dublin:D”

Above is a video by Charbax fromarmdevices.net/ showing a reference design for U8500 with MeeGo on it (cheers to @Cambo078 for the find), which would apparently be suitable for tablets as well as phone. Products with U8500 expected first half of next year (Max Before July 2011). Would the Nokia N9 be one of them?

Another video below shares  more info about the U8500 – this was shot back in February also by Charbax where the reference design devices had only Android and Symbian. U8500 is apparently up to 1.2GHz (Dual Core) with ARM  Mali 400 GPU.

Check out the 720p 3D game rendering. Also look at that 1080p playback on Symbian.

It’s worth noting that Nokia MeeGo phones may also use Intel chips in future – but at the moment, ARM is the better choice for the first Nokia MeeGo phone (If I recall correctly).

What does the U8500 feature?

The U8500 is the first mobile platform with full High-Definition 1080 progressive-scan camcorder capabilities. With its combination of a dual-core SMP processor and a high-end 3D graphics accelerator, the U8500 enables a full web-browsing experience for next-generation smartphones.

  • Full HD 1080p camcorder, multiple codecs supported
    (H264 HP, VC-1, MPEG-4)
  • High-resolution, touchscreen display support up to XGA (1024*768)
  • Simultaneous dual display support
  • High performance 3D graphics, support for
    OpenVG 1.1 and OpenGL ES 2.0
  • Dual camera support with Integrated ISP 18 Mpixel and 5 Mpixel
  • Wi-Fi, Bluetooth and GPS enabled platform
  • Built-in USB 2.0, HDMI out
  • Support for multiple operating systems, Symbian, Android
    and Linux-based platforms
  • Optional support for mobile TV standards

Technology

  • Highly efficient, low-power ARM dual Cortex™- A9 processor
  • Dual multimedia DSP for low-power, flexible media processing
  • High-bandwidth LP-DDR2 interface
  • ARM  Mali™ 400 GPU and NEON®CPU extensions
  • State-of-the-art HSPA (High-Speed Packet Access) Release 7 modem
  • Unique audio architecture with a wide range of audio codecs supported
  • Advanced power saving architecture enabling class-leading audio and video playback times

More ARM stuff

Whilst we’re on the topic of ARM Cortex A9 let’s check out how:

NVidia Tegra2 ARM Cortex A9 shows that a dual core performs up to 50% faster in rendering pages compared with ARM Cortex A9 with one of the cores disabled.

Here’s the Mali 400 GPU in action (but on the Samsung Orion ARM Cortex A9)

Finally from Nufront, their ARM Cortex A9 can run at 2GHz for Laptop and Desktop usage. There’s a fan going on with this one to cool down the chip. They say in the production you won’t need that (I think that’s what they said). This one powers Ubuntu 10.10 and Quake 3.

ARM Based MeeGo Nokia Tablet, Z500 is out to the world?

June 21, 2010 22 comments

From 2006 the Nokia 770 -4" WVGA resolution, crazy, that'll never take off.

Reports are now spreading that Nokia are “following” Apple and making a tablet.

These trace back to a Digitimes research analyst who says

“Talking with upstream component makers, the analyst pointed out that Nokia has already completed about 100 engineering samples ready for testing. The tablet PC’s panel size will be either 7- or 9-inch and manufactured by Foxconn International Holdings (FIH), the Hong Kong-listed handset subsidiary of Foxconn Electronics (Hon Hai Precision Industry), the analyst noted.”

And Eldar (who says he isn’t a Nokia hater but always slates Nokia at every moment possible – sometimes it’s warranted, most times it’s just unecessary, e.g. below) confirms the existance of a Nokia tablet.

Also remember that when Eldar bashed the N8’s camera, his “acquired proto” N8 was very different. Amongst other things, MR’s N8 didn’t even have the proper camera of the current (and soon retail) Nokia N8.

Unless Z500 is the name of the tablet, is Eldar referring to the aged Intel Atom Z500? But It’s already supposedly going to be ARM based. Unless there’s another Z500 non MeeGo Nokia tablet or it is on Sseries (S500?)

Stefan from intomobile mocks the idea of a Nokia tablet as their netbook Booklet 3G didn’t really fly that well with consumers. The latter was much too expensive for that category of product but with too little RAM (1GB instead of 2). Such a shame as it was Apple grade in terms of build – and that’s according to several macbook pro owners. That said, Stefan admits he isn’t a fan of the iPad either.

For the masses, a Nokia MeeGo tablet could really fly if priced adequately with competitive features. (As for MeeGo tablets in general, we’ll be seeing plenty from other manufacturers too, pushing Intel hardware. There’s already at least 4 showcased.). A tablet form factor is a great way to consume online media and be immersed in digital entertainment.

As for the ecosystem, developing for MeeGo is made easy and attractive with Qt. Not only does it mean cross platform across MeeGo phones, tablets, netbooks and other devices but other operating systems too, not just Symbian but potentially Android, Window and Mac as long as Qt is used. There’s massive support behind MeeGo, not just Nokia and Intel, but other big industry players too  (Acer, Asus, Cisco, BMW, Gameloft etc)
