AnandTech | Apple’s Cyclone Microarchitecture Detailed

So for now, Cyclone’s performance is really used to exploit race to sleep and get the device into a low power state as quickly as possible. via AnandTech | Apple’s Cyclone Microarchitecture Detailed. Race to sleep, is the new, new thing for mobile cpus. Power conservation at a given clock speed is all done through […]

Intel looks to build ultra-efficient mobile chips Apple cant ignore

During Intels annual investor day on Thursday, CEO Paul Otellini outlined the companys plan to leverage its multi-billion-dollar chip fabrication plants, thousands of developers and industry sway to catch up in the lucrative mobile device sector, reports Forbes. via Intel looks to build ultra-efficient mobile chips Apple cant ignore (Apple Insider) But what you are seeing […]

ARM Pitches Tri-gate Transistors for 20nm and Beyond

. . . 20 nm may represent an inflection point in which it will be necessary to transition from a metal-oxide semiconductor field-effect transistor MOSFET to Fin-Shaped Field Effect Transistors FinFET or 3D transistors, which Intel refers to as tri-gate designs that are set to debut with the companys 22 nm Ivy Bridge product generation.

AnandTech – Applied Micros X-Gene: The First ARMv8 SoC

While everyone was focusing on the ARM v.7 (current generatation) chip architecture, APM has been focused on the 64bit ARM v.8 which promises to herald a new era of low power with Server level features. By estimates made in the article APM has a 1 year lead on any other current licensees of ARM designs. And with any luck they will be sampling products that meet their performance targets in March of 2012 (albeit in FPGA eval form) Read On:

Intel Responds to Calxeda/HP ARM Server News (Wired.com)

Wired.com isn’t the best at following the Cloud Data Industry. In fact at least they partially want to keep their advertisers happy so they will publish a Fear, Uncertainty and Doubt raising response direct from an Intel PR Engineer. Happily the Intel folks aren’t even fully aware of what people are doing with their SeaMicro and Quanta SQ-2 boxes and continue to beat the drum on Virtualized Servers on Multi-core, high-clocked chips. That’s the old school thinking on what a Compute Cloud can be. The New School says put the cloud in a single box, let the clock run slower and use less power and everybody wins. Read On:

ARM specs out first 64-bit RISC chips • The Register

With the announcements recently from Calxeda and HP now ARM is jumping back into the limelight. They are working on the next version of the ARM architecture which will feature a 64bit clean design (which some speculated was going to arrive with ARM-15). Although the current version of the ARM architecture and support 40bit data paths, anything wider than that has to be worked around through OS level support of the underlying workaround. In a word, it’s a non-trivial task. But things will get much easier with the next Rev. All hail Version 8

AnandTech – ARM & Cadence Tape Out 20nm Cortex A15 Test Chip

In past readings of announcements and analysis of announcements from ARM and Calxeda, I got the impression everyone was looking forward to ARM-15 4core cpus that had 64bit capability, specially the 64-bit addressing for large amounts of DRAM. Well now the first test chip for ARM-15 has been announced. And the timescale for the production release of that chips is now clearer. My only question is when will they announce the x64 version of ARM-15. Let’s first look at what’s been written so far. Read On:

Rise of the Multi-Core Mesh Munchkins: Adapteva Announces New Epiphany Processor – HotHardware

It seems like massive scale multi-core cpus are increasing in popularity. A third party competitor is entering the market with a mobile cpu co-processor. Adapteva is announcing the Epiphany co-processor, but the question is really what’s it good at, and who is going to integrate it into a new phone design. Read On:

ARM vet: The CPUs future is threatened • The Register

Many people have predicted the demise of Moore’s Law, only to have a new process or technology rush in to save the day. Current tools are variations on a theme started in the 1960s by Shockley, Fairchild, Intel and have continued to be refined over the years. Pure research in the tools and technologies underlying semiconductor manufacturing has been going on for decades. Work on Extreme UV has gone on for years, and yet is not widely adopted as the old tools continued to scale downward in the chip rulings. But time is running out and a former principle at ARM is letting the cat out of the bag.
