Embedded devices are likely to be 32-bit for a very long time yet. I'd consider 100+ years to be a reasonable number! 64-bit devices are much more complicated

64-bit devices are much more complicated (bus size, peripherals, part count) and therefore more expensive. If your entire task fits in a 32-bit space there is little motivation to use a 64-bit core.
- zokier 12y ago> 64-bit devices are much more complicated (bus size, peripherals, part count) and therefore more expensive I don't see why 64 bit core would imply any additional external complexity? Didn't 68k have 32bit core and work just fine down to 8bit external bus?
- bananas 12y agoIt won't on full SoC devices but most ARM embedded devices of that sort have all sorts of peripherals which are bus connected so the bus will need to be external.
