How to get the most out of the memory interface  The choice of DDR memory is a key factor in determining the cost and power of the smartphone. Low cost smartphones typically use a single 32-bit memory…

ARM products in server and networking? Yes, it’s happening and AMBA® 5 CHI is a big part of making that happen. The AMBA 5 CHI protocol enables the latest ARMv8 architecture Cortex®-A50…

ARM® AMBA® 5 CHI Memory Controllers work in concert with AMBA 5 CHI interconnects to provide controls to optimise data flows between many processors and the DDR memory.  In this blog I am going to tell…

ARM Big.LITTLE processing addresses one of today's most significant challenges: extending consumers' always on, always connected mobile experience with both improved performance AND longer battery life…

Following on from two earlier articles (Navigating the Cortex Maze and ARMv6-M vs ARMv7-M - Unpacking the Microcontrollers), you might be interested in a new piece on the ARMv7-A architecture and Cortex…

Recently, I wrote an article called “Navigating the Cortex Maze” (Navigating the Cortex Maze) That was intended as an easy way-in to the ARM processor range, covering Cortex-A (architecture…

Fact: The ARM architecture is the most widely licensed 32-bit embedded instruction set architecture in the industry. That fact makes the ARM Instruction Set Architecture (ISA) incredibly important to…

In the fast-paced technology world we are used to hearing about improvements from one product generation to the next. In the past, we have looked in great detail at the various different metrics used to…

I thought I'd post a short blog post about commonly asked questions on AMBA 4 ACE and system coherency.What does ACE mean?ACE is the "AXI Coherency Extensions" introduced with the AMBA 4 specification…

The Arm Cortex-M story has much depth and warrants some further explanation. You see, it doesn’t end with Armv7-M.

Hi,Just noticed jacobbeningo's excellent post (10 Tips for Maximizing Battery Life)  in Embedded on Maximizing Battery Life. Some really good advice which any designer should take note of. Thanks…

This blog was originally posted on 11 September 2013 on blogs.arm.comFollowing on from the UEFI 64-bit announcement, I like to announce the release of the ARM® Architecture Reference Manual (commonly known…

Introduction The ARM architecture is 28 years old this year. The ARM1 first ran code on 26th April 1985 at the office of Acorn Computers in Cambridge, UK. Since the formation of ARM (then called “Advanced…

During the last days of August 2013 I was in the wonderful city of Vancouver, Canada, to attend Unite 2013, one of the biggest events dedicated to Unity, the market-leading platform for creating high-quality…

I saw what looks like the start of a series of short videos on the ARMflix YouTube channel. Of course, it doesn't go into much details, but I thought it was a simple way to discover the series. As they…

Hello there!At this year's TSMC OIP event, I presented “Optimizing Cortex-A57 for TSMC 16nm FinFET” and it was a packed auditorium.I would like to thank ARM, TSMC and Cadence for such an impressive colloboration…

The implementation of multi-threading in multi-core processor systems is being heralded as a potential solution to the challenge of achieving ever-higher performance targets with strict limits on power…

In this blogpost, Gabor Ballabas and I share why and how we’ve set up a public buildbot for the LLVM AArch64 backend. This buildbot is part of the LLVM community’s continuous integration infrastructure…

Rest in Peace Symbian  After 11 years, this is the first quarter when a S60 Symbian phone will not be shipped. Though in its day, Symbian had a very strong fan base with over 75% market share, it has since…

It’s been a terrific year for the Mali™ Developer Resources team this year, with the Mali Graphics Debugger being released along with support for the ARM® Mali-T604 in ARM DS-5™ Streamline…
