AMD started using ARM Cortex A5 to add TrustZone security to their x86 processor, they followed with their ARM based Opteron A1100 processor for server last year, recently they announced Hierofalcon embedded processors powered by up to eight Cortex A57 processor, and starting this year and beyond, the company will launch “ultra-low power’ mobile SoCs using ARM cores, at least according to a leaked roadmap.
Two ARM families are planned:
- “Amur” APU planned for 2015 with:
- Up to 4 ARM Cortex A57 cores
- GCN Graphics Compute Units
- AMD Secure Processor (Trustzone?)
- ~2W TDP
- 20nm process, FT4 BGA package
- “Styx” APU planned for 2016 with:
- Up to two “K12″ CPU cores. These should be high performance custom-designed ARM cores.
- Next-gen GCN Graphics Compute Units
- Full HSA 1.0 support (Heterogeneous System Architecture)
- AMD Secure Processor
- ~2W TDP
- 14 nm process, FT4 BGA package
With this kind of thermal dissipation, AMD Android and Windows tablets are the likely candidates for such chips, as well as certainly low power mini PCs and HDMI sticks.
PS: I will be on the road for some time, so I’ll post a bit less often, maybe 4 to 5 posts a week, and as usual tips / post ideas will be very welcome.
