Whoa - this could be really interesting.
Imagine a hybrid x64/ARM system where you could run simpler, low-intensity tasks on your low-power ARM core (Twitter clients, Facebook, etc) but more intense tasks or entire applications (Photoshop, development IDEs, etc) on your x64-compatible chip.
Or a system where you take your ARM core + storage with you in your phone and dock it with an x64 core in your desktop.
- nickpsecurity 9y agoThere's been quite a few to do hybrid architectures with one article suggesting AMD might do x86 + ARM: https://www.extremetech.com/computing/182790-amds-next-big-gamble-arm-and-x86-cores-working-side-by-side-on-the-same-chip https://www.extremetech.com/computing/182790-amds-next-big-g... It was also done the other way around with RISC workstations like Sun's running UNIX on SPARC coming with x86 cards to run their apps. I never checked it out to see what it was like but it was an advertised feature of SunBlade workstations. Additionally, IBM made PCI cards that could run their mainframe code on regular systems. https://en.wikipedia.org/wiki/SunPCi https://en.wikipedia.org/wiki/SunPCi https://en.wikipedia.org/wiki/PC-based_IBM-compatible_mainframes https://en.wikipedia.org/wiki/PC-based_IBM-compatible_mainfr...
- pjmlp 9y agoThis has been typical approach in mainframes and other OSes with bytecode as executable file format. AS/400 architecture upgrades are done without any big worries about CPU backwards compatibility thanks to them being like this.
