I am excited to be speaking at the AMD Fusion Developer Summit. I shall be speaking, but in a talk that is not listed as part of the agenda, but as part of one of the keynote talks. As many of you may know, my appearance last year generated a lot of speculation about the nature of the relationship between ARM and AMD. I gave a talk about the things that the two companies agreed on rather than what we disagreed on. Mostly I talked about OpenCL and the importance of open standards going forward, and how that related to heterogeneous compute systems. This year, we have a great deal to discuss. ARM is all about low power and many people in the industry now realize that GPUs have a central role to play in providing highly energy-efficient computing. It’s an exciting future that can grow the ecosystem that surrounds computing. ARM’s unique portfolio of CPU, GPU, interconnect and physical IP puts us at the forefront of one of the most important technological changes in a long time. Reflecting on that and some of those changes, I will be making an announcement at the show.
I wonder what we will do together as a result of these momentous changes in the industry? It promises to be an exciting year ahead as the ecosystem will be strengthened even further.

Jem is an ARM Fellow and likes to think of himself as "The Godfather" to technical talent in ARM. After spending some time in his youth writing software for satellites and traffic-lights among other fascinating things, Jem spotted the technical inflection point of the mobile industry: graphics, video and other visual computing. As VP of technology in the Media Processing Division of ARM, Jem is busy with a lot of projects involving the future of cool ARM technology, which will revolutionise how people experience and interact with digital devices.

I'm really looking forward to seeing/reading about the event! Please let us know if there are any videos that become available online!
I do have a few questions: I see that Midgard has around 32K cache per core. What are the latencies (in cycles) like for access of this memory? What about latencies for snooping via cache-coherence? Are there pre-fetch operations to fill caches in anticipation of needing resources?
I've been curious about this for some time, though I understand if this information is still 'classified'.
Thanks for the post!

Thanks Jem! I have a particular use in mind, but I can always do profiling when the time comes to determine runtime performance characteristics! I have no doubt that Midgard will be extremely competent as a het-compute architecture.
