Yup, I saw it, what is he actually trying to say ? How can analog computer supercede digital, analogue is made too specific for only 1 task

- JumpCrisscross 5y agoWe have tonnes of computing power dedicated to repeatedly solving a simply-parameterised problem.
- rawoke083600 5y agoStupid question... with todays memory capacities....At what limit/size do we stop using matrix-ops and simply use lookup tables todo 'matrix-math' ?
- jeffbee 5y agoNot a stupid question. Economically, memory density will hit a brick wall soon. Developers should prefer to waste time and save space, since parallel computation will not hit a similar limit in the foreseeable future. Memory-to-core ratio is going to be falling.
- adgjlsfhk1 5y agoTLDR is you can't. For a very simple example, storing the products of all 3x3 matrices * length 3 vectors in Float16 precision would take 2^193 bytes (which is obviously impractical).
- kortex 5y agoIf that "1 task" happens to be performing matrix multiplication (or even merely fused multiply add), you can do a heck of a lot with that. You still need digital circuitry to support the IO, but the key idea is doing linear algebra in a way that is faster and/or generates less heat per unit compute.
- aidenn0 5y agoYour CPU has dedicated circuitry for performing CRC32 and AES rounds. That's as specific as any analogue computer...
- littlestymaar 5y agoAnd your mobile SoC likely has h264, h265 and VP9 dedicated circuits also, so it also works for quite complicated tasks too.
