I have been wondering recently if analog computing would make more sense for certain search algorithms, like protein folding simulations. Basically, let a set of potentials be placed in the op amp setting representing position, and let them miller integrate the surronding charges and watch it evolve. Basically, physical modelling directly. Im not sure of the state of analog device precision, drift, and temp stability these days but it might be worth a try.
- nickpsecurity 11y agoTake a look at these, esp math coprocessor: https://www.schneier.com/blog/archives/2015/07/friday_squid_bl_488.html#c6701962 https://www.schneier.com/blog/archives/2015/07/friday_squid_... The trick is using analog circuits for just what it's good for. The digital does the rest. Need to have them integrated well. Good news is analog works well with inexpensive process nodes like 350nm and digital stuff on them is inexpensive. Tekmos even can integrate 90nm digital with 350nm analog plus MPW's to keep things cheaper.
