MIT almost produces an optoelectronic computer chip
- jpdoctor 15y agoFYI: I first saw this headline in the late 80s.
- sp332 15y agoI don't see a real advantage to a optical link between the CPU and RAM. The copper only adds a quarter of a nanosecond to the latency anyway. The rest of the applications sound cool though.
- stewartbutler 15y agoIt only adds a quarter of a nanosecond at the current distance from the CPU, but using it you could place more RAM at greater distance on the motherboard without significantly increasing delays. For applications where you want to store large data structures entirely in RAM this would be ideal. Also, optical signals are less susceptible to RF interference from noisy components.
