A 16mhz 8bit processor can do it, not a 200+mhz 32bit Anyway, I'm not going to argue... really last time I'm speaking in this thread. Look, you completely missed what i was saying before. I worked a bit with ultrasound like signals, and all that signal processing stuff is quite similar to what is used in cases like Xterra and Equinox. Same dds-demod-multirate filter etc. So in our case one channel (I or Q) with DDS, demodulator and post demod mutltirate filter was consuming around 50 operations per sample with 32 bit integers. Actually some accumulators were wider than 32 bits, but not that important. Assuming that equinox processing is similar, works with four frequencies, has sampling frequency of 100kHz for simplicity, we are getting 80 millions of these calculations per second. It is already a significant portion of what M7 core can do at 200MHz. You keeps assuming that all it does is scans buttons and lights up segments on display, which is completely wrong.

Whilst processing power was being disputed.......my detecting pal found another 18k whooper with a fat emerald yesterday with his Tesoro Compadre!!!!!??? Hasn’t had it valued yet but it’s a tad over 16grams. Not sure what that converts to in mHz???? 1 1 Link to comment Share on other sites More sharing options...
LowTide Posted November 26, 2019 Share Posted November 26, 2019 Oh these Padawans........old Geezer talk to follow.........Why I remember a project we were doing for the U.S. Department of Transportation for Railway Safety Signaling.....and.....well we had Intel 8080‘s with 2K of Ram. One day it was announced we were going to get 4K of Ram. We broke out the bubbly.....oh the feats we would be able to accomplish with 4K!!!!! We threw a heck of a party.....but not much coding got done the following day. 1 Link to comment Share on other sites More sharing options...
Hades Posted November 26, 2019 Share Posted November 26, 2019 8051 was my first true love ? It had the whole 128 bytes of RAM Link to comment Share on other sites More sharing options...
Cal_Cobra Posted November 26, 2019 Share Posted November 26, 2019 The Apollo Lunar Module only had 2K of core memory. I'm pretty sure my iPhone could've ran everything and then some that a 1960's NASA Mission Control center that was using IBM mainframes ? 1 Link to comment Share on other sites More sharing options...
Hades Posted November 27, 2019 Share Posted November 27, 2019 There should be a slot for 8" floppy somewhere. Or punch cards ? 1 Link to comment Share on other sites More sharing options...
mh9162013 Posted November 30, 2019 Share Posted November 30, 2019 During WW2, the total combined computing capacity of the Allies was less than what you buy in a birthday card at the store that sings happy birthday. And everyone readily accepts that such a card is disposable, at least on a hardware level. Link to comment Share on other sites More sharing options...
