Teknologi Terbaru - Sarung Tangan Ajaib Untuk Masa Depan
Teknologi Terbaru - Baru – baru ini para peneliti berhasil menciptakan dan mengembangkan sebuah sarung tangan dengan teknologi canggih atau bisa dikatakan sebuah sarung tangan ajaib untuk pengembangan di masa depan. Sarung tangan ini merupakan sarung tangan futuristic yang dikembangkan oleh para ahli untuk bidang kesehatan yaitu mempermudah kerja doketr dalam melakukan penangan perasi atau pemindaian ultrasound (scan) yang dilakukan melalui ujung jari dari dokter tersebut.
Sejatinya sarung tangan diciptakan hanya untuk mensterilkan tangan – tangan para dokter saat melakukan perawatan dan melakukan tindakan operasi bedah pada pasien di rumah sakit. Sarung tangan tersebut berfungsi untuk melindungi luka dari bahaya kuman yang dimungkinkan ada pada telapak tangan dokter dan perawat di rumah sakit saat melakukan tindakan.
Namun dengan perkembangan teknologi sarung tangan kini menjdi hal yang sangat mendukung dan dikembangkan untuk semakin memudahkan pekerjaan dokter saat melakukan pemindaian. Sehingga mempermudah, mempercepat dan tidak memiliki resiko yang sangat besar saat dokter melakukan tindakan.
Para peneliti ini telah berhasil menciptakan sebuah perangkat yang dapat melakukan respon yang sangat tinggi dengan presisi yang cukup tinggi bagi ketegangan dan juga tekanan yang dilakukan dengan menggunakan gerakan dari  jari jemari dokter. Pengembangan penilitian ini diakui sangat begitu rumit dan penuh ketelitian dalam menyusun setiap perangkatnya sehingga hasilnya nanti diharapkan akan lebih baik dan benar-benar berhasil digunakan.
Para peneliti ini juga berharap bahwa pengembangan penelitian ini akan berhasil sehingga semakin mendukung proses pemindaian dalam dunia kesehatan dan memudahkan kerja dari para dokter saat melakukan tindakan pemindaian. Selain itu juga ini menjadi langkah awal untuk membuat sebuah robot khusus bedah yang dapat melakukan interaksi bersama tim kesehatan yang dilakukan melalui sentuhan.
Para peneliti juga mengungkapkan bahwa perangkat sarung tangan ini juga memiliki sebuah sensor sehingga mampu dan dapat mengukur sebuah gerakan serta suhu yang terjadi saat digunakan. Selain itu, sebuah pemanas yang memiliki skala kecil yang bertindak sebagai suatu actuator untuk ablasi juga tindakan operasi lainnya.

Teknologi UEFI pengganti Teknologi BIOS

UEFI sebagai pengganti teknologi BIOS. Era BIOS akan segera berakhir dan berganti teknologi terbaru UEFI. Teknologi ini bisa mereduksi waktu start-up, sehingga komputer bisa menyalakan dalam hitungan detik.


Produsen teknologi BIOS kini membuat perangkat lunak start-up baru yang dikenal dengan nama Unified Extensible Firmware Interface (UEFI). Hasilnya generasi terbaru dari komputer rumahan ini akan mampu menyalakan sistem komputer dalam hitungan detik.

Teknologi BIOS telah digunakan di komputer sejak 1979. Teknologi ini tidak pernah didesain ulang dalam kurun waktu begitu lama sehingga menjadi alasan mengapa komputer modern menghabiskan waktu begitu lama untuk mulai aktif.
Di sisi lain, UEFI telah dikembangkan untuk memenuhi kebutuhan komputer modern dan akan segera diterapkan di banyak komputer baru. Software ini mampu ‘aktif’ dan ‘nonaktif’ dalam hitungan detik.
“Saat itu, perangkat lunak ini memungkinkan Anda hanya membutuhkan waktu 25 sampai 30 detik sebelum melihat tampilan awal OS komputer Anda,” kata kepala forum UEFI Mark Doran. “Ini memang tidak benar-benar instan, namun jauh lebih baik dari BIOS yang konvesional.”
Teknologi BIOS telah digunakan di beberapa evolusi komputer modern seperti keyboard yang terkoneksi dengan USB atau flash drive.
Para ahli berharap UEFI akan mendapatkan pijakan yang signifikan dalam pasar komputasi pada awal tahun depan. Banyak perusahaan elektronik yang bekerja keras untuk mengurangi waktu aktivasi mesin komputer mereka.
Ini adalah faktor yang sangat penting bagi perangkat seluler dan komputer tablet yang akan datang. Sistem operasi Chrome milik Google juga dikabarkan memiliki waktu ‘boot-up’ dalam hitungan detik.

The AMD Trinity Review (A10-4600M): A New Hope

AMD’s Heterogeneous Computing with Trinity
It’s not all about just CPU or GPU performance, though—or at least that’s what we’ve been hearing from various parties for a while now. The real question is how a platform performs as a whole. There are some tasks where pure CPU performance is what really matters, and there are other tasks where the parallel nature of GPUs pays serious dividends. AMD (and NVIDIA) has been pushing for more applications to make use of the GPU for tasks where it can provide a lot of number crunching prowess.
With Trinity, AMD provided us with a selection of applications that now leverage—to varying degrees—AMD’s App Acceleration, OpenCL, OpenGL, or other tools. For some of these applications, we don’t have any good way of measuring performance across a wide selection of hardware, and for some of those where benchmarks are possible I’ve run out of time to try to put anything concrete together. I don’t want to skip this section entirely, so what follows is a list of the applications, how they benefit from heterogeneous compute, and some general impressions of the application. We also have graphs for a few of the applications where performance seemed to matter the most.
Adobe Flash 11.2—The latest version of Flash continues to add GPU acceleration features, and now there are 3D hooks in addition to the video offload acceleration we first saw with Flash 10.x. There’s not too much of note here, as NVIDIA and Intel also support the latest features of Flash 11.2. Flash works fine on Trinity, but the same goes for Ivy Bridge and various NVIDIA GPUs. If you never saw the Epic Citadel demo for iOS or Android, there’s now a Flash-based version of the same demo that will run in your browser. (Warning: that link can take 10-15 minutes on a decent connection to download all the textures and other data!) Epic Citadel looks just as nice as it did on iOS, but now we need some actual games to take advantage of the tools. Then perhaps we can start looking into benchmarks of browser games or something….
Adobe Photoshop CS6—Photoshop started to take advantage of GPU acceleration back with the CS4 release, using OpenGL to improve performance on certain filters and features. With CS6, Adobe has begun using OpenCL. Fundamentally, I’m not sure how big of a change this represents, but there are quite a few functions in Photoshop that are now supposed to be faster/better with an OpenCL compatible graphics card. There are also two new features that leverage OpenCL; one is Iris Blur, which allows you to mimic depth of field using Photoshop instead of your camera, and the other is Liquify. Unfortunately, I’m by no means a Photoshop expert, so I’m not sure how much the features really help “power users”. I did try doing a benchmark of general Photoshop CS6 performance using the Photoshop Retouch benchmark with and without GPU acceleration enabled; unfortunately, it looks like most of the filters in that action script don’t benefit from the GPU acceleration, as the scores I got were essentially unchanged with or without GPU/OpenCL enabled. Overall, I’ll take the GPU acceleration, but for most of what I do in Photoshop it doesn’t appear to benefit; if you’re interested, you can read more about AMD’s work with Adobe.
GNU Image Manipulation Program (GIMP)—Going along with Photoshop CS6, AMD provided a special preview build of GIMP 2.8. GIMP is sort of the poor man’s Photoshop, as it’s completely free. At present, there are 19 filters that utilize OpenCL to speed of processing, and over the coming months as the release version of GIMP looks to take their new engine live there will undoubtedly be more additions. For now, probably only five of the filters are things I would use (e.g. noise reduction, maybe a light blur). I tested several of these, and there is sometimes an order of magnitude speedup vs. doing the work on just the CPU. The problem is that it also looks like GIMP isn't incredibly well threaded in many of these tasks, putting multicore CPUs at a disadvantage. My biggest complaint isn’t even about performance, though; sadly, I just find the GIMP UI and general performance to be really bad compared to Photoshop. I've tried several times over the years to use GIMP instead of Photoshop, but I’ve never felt comfortable with the tool. If on the other hand you prefer GIMP, hopefully when the current GEGL menu gets integrated into the main program you’ll realize a healthy performance boost.
Assisted Video Transcoding—ArcSoft MediaConverter 7
ArcSoft MediaConverter 7.5—MediaConverter should be a familiar name by now if you’ve been following our reviews, as it’s one of the showcase titles for Intel’s Quick Sync transcoding. When we reviewed Ivy Bridge last month, we found that on Llano at least the version of MediaConverter we had ran slower on the GPU than on the CPU; with Trinity on the other hand, enabling GPU acceleration results in times that are about 60% faster than the CPU alone. That’s a good performance increase, but we’re looking at 154 seconds on the CPU compared to 98 seconds using the GPU. In contrast, dual-core Sandy Bridge on CPU transcoding took 127 seconds and with Quick Sync it only took 28 seconds—a 5X improvement. Quad-core Ivy Bridge was just as impressive, going from 68 seconds on the CPU down to 16 seconds with Quick Sync (4.25X). We’ve been hoping to see something more from AMD’s new Video Codec Engine (VCE), first announced over six months ago with HD 7970, but unless there’s substantial room for improvement it looks like Intel’s Quick Sync will continue to be the fastest transcoding tool for now.
Assisted Video Transcoding—CyberLink MediaEspresso 6.5
CyberLink MediaEspresso 6.5—This tool is very similar to MediaConverter, and the results are also better this time around. We measured the assisted encode time at 74 seconds compared to 135 seconds on the CPU alone. The 74 second transcode time actually makes Trinity potentially faster than CPU-based transcoding on dual-core Sandy Bridge, but again Quick Sync (25 seconds on SNB, 12 seconds on IVB) remains the fastest way to transcode.  Considering both of these tools are apparently using VCE, I have to state that I’m disappointed; with VCE I was expecting performance similar to what Intel is getting with Quick Sync—four or five times faster than CPU-based encoding for the same APU. That Trinity isn't quite twice as fast with VCE is unfortunate; even though there's a decent improvement, Intel is in a completely different category of performance. We’ll have to wait and see if anything more develops with VCE.
File Compression—WinZip 16.5 and 7-Zip 9.2
Handbrake— Yep, this popular open source video transcoding app is getting an OpenCL facelift. Check out our separate post on it here.
WinZip 16.5—This final application is one that I can see being very useful, assuming we see similar advancements in other compression utilities. WinZip 16.5 now supports OpenCL to improve compression times. We tested by compressing the entire Cinebench 11.5 directory with and without OpenCL enabled, and we also compared the results with 7-Zip. On Trinity, performance improved by about 20%, which is decent; Llano sees an even larger 28% improvement. Meanwhile, Sandy Bridge using CPU-based compression is about as fast as Trinity with OpenCL, and Ivy Bridge is still faster, but the 20% increase for “free” is nothing to scoff at. Unfortunately for WinZip, 7-Zip compressed the same directory to 95MB vs. 108MB in roughly the same time as the non-OpenCL WinZip, and 7-Zip is completely free and doesn't nag you and tell you to buy it. Where WinZip 16.5 is a good proof of concept, what will really help AMD is if all the other compression utilities (7-Zip, WinRAR, etc.) all start using OpenCL or other tools to improve performance.
The majority of the applications continue to focus on video and image manipulation, likely because those are areas where the parallel nature of GPUs can be readily utilized. WinZip on the other hand is an application showing other potential uses for GPGPU and heterogeneous compute. We’d love to see even more adoption of OpenCL and similar tools, but the stark reality is that coming up with new and useful ways of doing this is difficult—if it were easy, everyone would do it! The good news is that giving the creative people of the world more tools with which to work can only help, and we’ll just have to wait and see what else comes out.
There’s another interesting sidebar worth mentioning here. OpenCL is an open standard, and the latest Intel drivers actually install an OpenCL driver on Ivy Bridge and Sandy Bridge. Not surprisingly, not all implementations are created equal, so even with Intel’s drivers we couldn’t enable OpenCL in Photoshop or WinZip; GIMP on the other hand apparently worked okay with OpenCL on Intel—we measured a 5X performance improvement of the Noise Reduction filter with Ivy Bridge. Trinity also came in slightly faster with both leveraging OpenCL, while Intel was nearly twice as fast without.

Computex 2012: AMD Trinity desktops delayed until October

There are motherboards to be seen, but there wasn't a Trinity APU in sight at Computex.

Sumber information...



AMD’s recent launch of its Trinity APUs focused heavily on laptops and the expectation was that the desktop variants of the APU would arrive shortly afterwards, maybe in the August timeframe.
On the show floor of Computex we saw several motherboard designed around the new FM2 socket needed for Trinity. Unfortunately, much like last year when AMD’s Bulldozer CPU missed Computex, it looks like actual Trinity CPUs are a long way off, with several people mentioning that the launch window is now October.

From our experience with the laptop A10 APU, the mobile market is probably the best place for AMD to focus, given that the APU has noticeably lower CPU performance than equivalent Intel CPUs. This is more forgiveable in laptops, where power savings and a much better base level of GPU performance than Intel means that the total experience is quite tempting.

On the desktop however, you just have a processor that is slower than Intel’s - and the likelihood is that the system will have a discreet GPU as well. But there are advantages to be had, especially for media boxes designed to use the media acceleration functionality of the APU.

For now at least we’ll just have to wait and wonder about what niche AMD can carve out on the desktop. The motherboards look solid enough, with the new A85 chipset largely the same as the existing A75 chipset for the previous generation Llano APU (AMD has added two more SATA 6Gbps channels for a total of eight).

Gigabyte is using this new chipset on several motherboards that we saw today, whilst ASRock has deigned to use the older A75 chipset with the new FM2 socket, trading in two Sata channels for cost savings).
