Data centers and the evolving enterprise also will radically alter the design landscape. "Data growth is unsustainable unless we design servers in a
different way," East said. "But it is starting to happen. We've been
working on this for four or five years and it is starting to show
Server processors would mimic the mobile SoC evolution, he added.
Single-core chips with virtualization would be replaced by
multicore processors; these in turn would be replaced by
heterogeneous processors with many different cores and hardware
accelerators. Already, the market is requiring many
different server types, East noted.
Grey, CEO of Linaro, which previously provided Linux-based software for mobile applications, announced that the
organization would add open-source software development for
the enterprise to its to-do list. Linaro
already has engaged with a dozen companies to work on core Linux
software for ARM-based servers, and initial software will be
delivered before the end of this year, Grey said. The organization has 120 software
engineers, and that number will double over the next 12 months, he added.
Althoff said Oracle is looking for ways to collaborate with ARM,
particularly around the Java programming language. Oracle is targeting both the 32- and 64-bit levels and across the entire ARM ecosystem. "We have 9 million Java
developers supporting about 3 billion devices running Java," Althoff said. "If the
forecasters are right about the Internet of Things and
machine-to-machine communications, that is about to be turned on its
head. It's about to explode, 50 billion devices, 100 billion
Althoff added that Java has recently been ported to run
on Cortex-M cores that are typically used in microcontrollers. "We want to have Java run everywhere," he said.
That provided an opening for East to address IoT and to announce that ARM is joining with CSR, Neul and Cable and
Wireless to support the Weightless standard. The proposed wireless technology
spec for communications between a basestations and thousands of
machines would use unoccupied TV transmission channels, so called
white-space radio. This would serve as a possible platform
for multiple applications that could rely on M2M
Chips for such applications must be small, low-cost and ultra-low power, all attributes that play to strength of ARM processor core
architectures, East claimed. "Technology is no longer the barrier. Connectedness is now the
East added, "If we apply the same partnership approach, the industry is in a
better position than we have ever been in before to make the world

@wsw1982. Watch out. You are in the wrong place. This is ARMTimes (aka EETimes) and you cant say anything bad about ARM. Even though the Exynos in your Chromebook is sucky and consumes about 10W, you cant say anything negative.
It's funny that at the mean time ARM is losing in power efficiency. The Samsung Exynos 5 is power hungry in both Cromebook and Nexus 5. The ARMy smartphones consume more power than the medfield phones. The ARM's arguments are always about the maximum performance and idle power consumption, while the others about both the full load performance and top power consumption.
I visited TI's Kilby labs a while back and they were doing all kinds of experiments with motors to reduce power consumption. It was fascinating, because you don't often think of semiconductor firms doing motor research... but low power needs are pushing the big players into those spaces
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
