I am particularly curious to see what packaging options this device will come in. I am wondering if this product is aimed at the Cortex M market, or the lower end of the Cortex A series? If it is aimed at the M, say M4F with a higher clock speed, it would be interesting to see this type of device in a QFN and QFP. If it is competing with the A series, I expect that this will only be available as a BGA.
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.
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.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
