Hot Chips was a good example showing the rise of ARM processors - both tutorials included ARM speakers, the two keynotes were from ARM and ARM licensee Qualcomm, there was a whole session just for ARM server chips, and one of the biggest mystery unveiling was Nvidia's Denver ARMv8 CPU.
I thought the Applied Micro XGene roadmap was impressive - the company has the first generation in production, the second generation sampling, and the third gen defined and sampling next year. APM has to make up for some slips, but they are the reference design that most ARMv8 software is targeting.
AMD's Seattle ARMv8 SoC incorporates a wide selection of I/O on chip, in addition to the eight Cortex-A57 CPUs, in order that AMD can apply the chip to multiple customer demands. The "swiss army knife" approach to the number and selection of I/O really allows AMD to showcase its capability to build customized server solutions for specific customer I/O requirements.
The oddball presentation was the ARM/Avago (former LSI Logic) where the tie-in was ARM's CCN-508 interconnect fabric used in the Avago Axxia 5516. The sixteen ARM Coretx-A15 cores in the 5516 can be allocated for control and data plane processing for Open Flow 1.3 network routing. Now that Intel is buying the business, I expect there's going to some changes made to the roadmap for future Axxia processors.
