Must be 32 bit

Chatting with fave analysts Kevin Krewell and David Kanter in the IDF media room I realize Quark must be 32 bit. There's just no need for 64-bit addressing in IoT for a loooooong time.

Is it really more secure?

At least according to a few software engineers I asked about this subject, symantec and wind river doesn't offer something unique security-related. It's mostly branding. I wonder if this is the only benefit for this chip, or are there others planned?

Of course you can be secure with other CPU, too. As an example, why is ARM used inside chip+PIN card reader ?

I do not want to say using Quark was a bad decision, just that public justification may differ from actual one.

GSMD , very interesting post.


Could you please tell a bit about where mcaffee security is relative to to other software stacks?

Getting better opportunities on the security and embedded internet stack because of very long stay in the computing environment will be a very good plus point for Intel on getting proven in IoT Processor segment.

Quark is 32-bit Pentium based ISA with single Core, single Thread.

@GSMD: Thanks for weighing in!

Question: Doesn't the x86 support the same hardware root of trust the Trusted Computing Group nspecified and ARM Trustzone implmewnts in its own way?

I don't know anything, except that AMD64 introduced a lot more than just a bigger address space.  IA32 is really not a good/modern ISA, and it would be quite strange to see Intel falling back 10+ years.  one real register, stack-based x87, no vectorization, etc.  at the time, 64b extensions were justified as not adding a lot of chip complexity - of course that's relative to OoO/superscalar stuff.
