ARM has revealed its latest processor for mobile devices, the Cortex-A12, which it has developed for the booming mid-range segment. Also new is the Mali-T62, a new mobile GPU that can be paired with Cortex-A12 cores. The Cambridge, England based chip designer also revealed the complementary Mali-V500 video support chip and POP IP technology that reduces system bandwidth and power requirements, while enabling playback of protected video content using TrustZone verification.
Samsung on Wednesday ended one of the largest rumors surrounding the new Galaxy S with news of its main processor. The Exynos 4 Quad carries a namesake four ARM Cortex-A9 cores and is made on a newer, smaller 32 nanometer process. Although it clocks in at the same 1.4GHz as in newer Samsung phones, it's roughly twice as powerful while using 20 percent less power, the company claimed.
The market for embedded processors could grow to ten times the size of the market for mobile device chips, according to ARM CEO Warren East. In an interview with Mobile World Live, East indicated that while mobile devices remain a profitable sector for the company, ARM has its eye on getting its components into a much wider array of products.
ARM on Tuesday rolled out a unique variant on the Cortex-A15 designed to bring the next-generation chip to shelves faster and with less power use. A new hard macro variant that has fixed specifications, including quad cores clocked at 2GHz based on a 28 nanometer TSMC-made (Taiwan Semiconductor Manufacturing Company) design, instead of the "soft core" that lets firms heavily customize an ARM design to their own ends. In return, however, it's both faster to implement and uses the same power as the earlier Cortex-A9.
A new rumor Monday has shown that Apple might be examining the effect of the A5X chip in an iPhone. The 9to5 claim has a version of the new iPad's chip was reportedly sitting in the existing iPhone 4S body as a test mule. The design, codenamed N96, reportedly has the same 1GB of RAM, although no mentions were made of what might be different.
More details of NVIDIA's Tegra 4 have emerged that could point to as much of a leap in speed as with the last generation. Possible leaks from VR-Zone have shown the line keeping the "4-plus-1" quad-core design but jumping to the much newer ARM Cortex-A15 architecture inside, which should give it a leap in speed at the same clock speed. The clock speeds themselves should climb from 1.5GHz to 2GHz to give it brute force improvements.
Apparent new leaks have hinted that NVIDIA's next-generation Tegra, for now called the Tegra 4, should be a generational leap. The future 28 nanometer chip was said by VR-Zone's tips to be getting GPGPU support to use its graphics core for boosting CUDA, OpenCL, and other general-purpose tasks. The simple addition would hint at a graphics core multiple generations newer than what's in the Tegra 3, which dates back to the 2006-era PlayStation 3.
India took quick action to address quality gripes with the original Aakash tablet by releasing an upgraded version. The new Android 2.2 model is still made by Datawind but is roughly twice as fast, carrying a 700MHz ARM Cortex-A8 chip. Its much-maligned resistive, seven-inch touchscreen has been replaced with a much more responsive capacitive screen.
Computer chipmaker ARM on Tuesday claimed that its new Cortex-M0+ processor is the world's most energy-efficient microprocessor. The 32-bit chip is said to consume just nine microamps for every 1MHz on its 90-nanometer, low-power architecture. This is about a third of the energy of any 8- or 16-bit processor on the market, ARM said, while also outperforming them.
Well-known for its pre-release Apple access, Vietnam's Tinhte in a pair of posts has gotten early access to the third-generation iPad and answered some of its core questions. Apart from proving that the box will be very familiar, the site confirmed that the new iPad has an LTE toggle to save power. Most Android devices often won't allow this without a third-party app or hack.
