In terms of performance, while it CAN be done, it would be several orders of magnitude slower than even the slowest phones on the market today.
I'll just take the processor module as an example: in a modern consumer processor, bidirectional bus speed to the CPU can be upwards of 25.6 GB/s (gigaBYTES) - compare that to the 50 MB/s typical speeds of your average 802.11 network. It wouldn't even make sense for the phone to have RAM when using such a slow interlink as it would be no faster than flash memory.
Yes, it CAN be done, but it would be so slow as to be unusable for most purposes.
- regularfry 13y agoIf you were going to do something like this, it makes more sense to think in terms of a network, rather than a bus. What you'd be transmitting wouldn't be the memory contents, it would be the (much smaller) computation results. That does have implications for where you cut the modules up (you'd want your GPU to be sat right next to the screen, for instance), but doesn't fundamentally damage the core idea.
- thedufer 13y ago> What you'd be transmitting wouldn't be the memory contents, it would be the (much smaller) computation results. The only way I can make that sentence sensible is to assume that you're putting the CPU and memory on the same module. Given that there are basically 4 pieces that make sense to swap (screen, CPU, RAM, battery), you're already pretty far down the path of engineering this into what we already have.
