Don't have a meltdown boss; I really do need a new phone

The fact that Spectre and Meltdown combined affect 72% of Android and Apple devices on the market offers a compelling reason to request a new work phone.  In many cases the devices being used in large enterprises are old enough that there is no patch coming, the story Slashdot linked to suggests almost 25% of the devices in use will fall into that category.  Since those devices have also missed out on numerous security features which were added in newer operating systems, you should have enough reasons to justify the expenditure.  The next time you are banking or dealing with a service provider in your own personal life you might want to peek at the phone they use and make sure they aren't endangering your own information.

"Analysis of more than 100,000 enterprise mobile devices shows that just a tiny percentage of them have been protected against the vulnerabilities -- and some simply may never be protected. Security firm Bridgeway found that just 4 percent of corporate phones and tablets in the UK have been patched against Spectre and Meltdown."

ARM Releases Cortex-A72 for Licensing

On February 3rd, ARM announced a slew of new designs, including the Cortex A72.  Few details were shared with us, but what we learned was that it could potentially redefine power and performance in the ARM ecosystem.  Ryan was invited to London to participate in a deep dive of what ARM has done to improve its position against market behemoth Intel in the very competitive mobile space.  Intel has a leg up on process technology with their 14nm Tri-Gate process, but they are continuing to work hard in making their x86 based processors more power efficient, while still maintaining good performance.  There are certain drawbacks to using an ISA that is focused on high performance computing rather than being designed from scratch to provide good performance with excellent energy efficiency.

ARM has been on a pretty good roll with their Cortex A9, A7, A15, A17, A53, and A57 parts over the past several years.  These designs have been utilized in a multitude of products and scenarios, with configurations that have scaled up to 16 cores.  While each iteration has improved upon the previous, ARM is facing the specter of Intel’s latest generation, highly efficient x86 SOCs based on the 2nd gen 14nm Tri-Gate process.  Several things have fallen into place for ARM to help them stay competitive, but we also cannot ignore the experience and design hours that have led to this product.

(Editor's Note: During my time with ARM last week it became very apparent that it is not standing still, not satisfied with its current status. With competition from Intel, Qualcomm and others ramping up over the next 12 months in both mobile and server markets, ARM will more than ever be depedent on the evolution of core design and GPU design to maintain advantages in performance and efficiency. As Josh will go into more detail here, the Cortex-A72 appears to be an incredibly impressive design and all indications and conversations I have had with others, outside of ARM, believe that it will be an incredibly successful product.)

 

Cortex A72: Highest Performance ARM Cortex

ARM has been ubiquitous for mobile applications since it first started selling licenses for their products in the 90s.  They were found everywhere it seemed, but most people wouldn’t recognize the name ARM because these chips were fabricated and sold by licensees under their own names.  Guys like Ti, Qualcomm, Apple, DEC and others all licensed and adopted ARM technology in one form or the other.

ARM’s importance grew dramatically with the introduction of increased complexity cellphones and smartphones.  They also gained attention through multimedia devices such as the Microsoft Zune.  What was once a fairly niche company with low performance, low power offerings became the 800 pound gorilla in the mobile market.  Billions of chips are sold yearly based on ARM technology.  To stay in that position ARM has worked aggressively on continually providing excellent power characteristics for their parts, but now they are really focusing on overall performance and capabilities to address, not only the smartphone market, but also the higher performance computing and server spaces that they want a significant presence in.
