MS speeds ahead as Google stalls on hardware acceleration

Video thrilled the browser star


On the same day that Google Chrome coders pushed back some of the hardware acceleration features they had planned for version 8 of Mountain View’s browser, it was revealed that Microsoft had been awarded a patent for GPU-Accelerated video encoding.

Google has been moving speedily through its own stack of test builds for Chrome, with the company pushing out a first dev version of its 8 code yesterday.

However, in its haste to get the new iterations of the browser out the door, Google also appeared to be conceding that it had to pull back on planned hardware acceleration APIs for CSS rendering, large layers and opacity fixes in version 8, as noted by CNet.

All of which means that those features, along with Chromium hardware-based video decoding, probably won’t see the light of day until the browser hits version 9. That’s not necessarily a big deal, given Google’s rapid release schedule; the code will probably be piped out to its dev channel before the year is out.

Microsoft, meanwhile, is making a big play for hardware acceleration in its Internet Explorer 9 browser. And yesterday, it was finally granted a patent for GPU-Accelerated video encoding after applying for it way back in October 2004, or the days of yore when folk still used a thing known as a desktop computer running Windows XP. Oh, hang on…

But getting the invention’s seal of approval from the US Patent and Trademark Office now is arguably brilliantly timed for Microsoft.

“Because the computational complexity of motion estimation is high, motion estimation occupies a significant portion of the processing power and resources that are needed for the whole encoding process and is usually the bottleneck,” reads the patent’s filing to the USPTO.

“Thus, there is a need for computers to more efficiently perform motion estimation so that video encoding can be accelerated without simply improving the speed of CPUs.”

It’s unclear if the patent could yet be a roadblock to Google’s development of its Chrome browser, but it’s fair to say that MS just scored a small win in the hardware acceleration race. ®

  • Google keeps legacy G Suite alive and free for personal use
    Phew!

    Google has quietly dropped its demand that users of its free G Suite legacy edition cough up to continue enjoying custom email domains and cloudy productivity tools.

    This story starts in 2006 with the launch of “Google Apps for Your Domain”, a bundle of services that included email, a calendar, Google Talk, and a website building tool. Beta users were offered the service at no cost, complete with the ability to use a custom domain if users let Google handle their MX record.

    The service evolved over the years and added more services, and in 2020 Google rebranded its online productivity offering as “Workspace”. Beta users got most of the updated offerings at no cost.

  • GNU Compiler Collection adds support for China's LoongArch CPU family
    MIPS...ish is on the march in the Middle Kingdom

    Version 12.1 of the GNU Compiler Collection (GCC) was released this month, and among its many changes is support for China's LoongArch processor architecture.

    The announcement of the release is here; the LoongArch port was accepted as recently as March.

    China's Academy of Sciences developed a family of MIPS-compatible microprocessors in the early 2000s. In 2010 the tech was spun out into a company callled Loongson Technology which today markets silicon under the brand "Godson". The company bills itself as working to develop technology that secures China and underpins its ability to innovate, a reflection of Beijing's believe that home-grown CPU architectures are critical to the nation's future.

    The CEO of China’s top e-commerce company, JD, has pointed out the economic impact of China’s current COVID-19 lockdowns - and the news is not good.

    Speaking on the company’s Q1 2022 earnings call, JD Retail CEO Lei Xu said that the first two years of the COVID-19 pandemic had brought positive effects for many Chinese e-tailers as buyer behaviour shifted to online purchases.

    But Lei said the current lengthy and strict lockdowns in Shanghai and Beijing, plus shorter restrictions in other large cities, have started to bite all online businesses as well as their real-world counterparts.

  • Foxconn forms JV to build chip fab in Malaysia
    Can't say when, where, nor price tag. Has promised 40k wafers a month at between 28nm and 40nm

    Taiwanese contract manufacturer to the stars Foxconn is to build a chip fabrication plant in Malaysia.

    The planned factory will emit 12-inch wafers, with process nodes ranging from 28 to 40nm, and will have a capacity of 40,000 wafers a month. By way of comparison, semiconductor-centric analyst house IC Insights rates global wafer capacity at 21 million a month, and Taiwanese TSMC’s four “gigafabs” can each crank out 250,000 wafers a month.

    In terms of production volume and technology, this Malaysian facility will not therefore catapult Foxconn into the ranks of leading chipmakers.

  • NASA's InSight doomed as Mars dust coats solar panels
    The little lander that couldn't (any longer)

    The Martian InSight lander will no longer be able to function within months as dust continues to pile up on its solar panels, starving it of energy, NASA reported on Tuesday.

    Launched from Earth in 2018, the six-metre-wide machine's mission was sent to study the Red Planet below its surface. InSight is armed with a range of instruments, including a robotic arm, seismometer, and a soil temperature sensor. Astronomers figured the data would help them understand how the rocky cores of planets in the Solar System formed and evolved over time.

    "InSight has transformed our understanding of the interiors of rocky planets and set the stage for future missions," Lori Glaze, director of NASA's Planetary Science Division, said in a statement. "We can apply what we've learned about Mars' inner structure to Earth, the Moon, Venus, and even rocky planets in other solar systems."
