If I understand the concept of #FPGA properly, it uses "generic" electronic modules (FPG arrays) that can be (reversibly?) "personalized" to behave like a custom desinged circuits.
To personalize them, we need:
1. Some design and development environment, where we design and test specific configurations for given functionality. And this part is rather resource-intensive.

2. Some "flashing" environment to "imprint" existing models onto generic FPGA modules. Which is much less resource-intensive than the previous part.

Now, I can imagine that, for the sake of #maintenance and #resillience, I may use FPGAs to build all kinds of devices around them. Then, just in case of failure (EMP, maybe) I can safely stock a pile of generic modules, an imprinter and a library of models so I can replace whatever is broken, without looking for a specialised chip.

Does it make sense and why not?

You've got the general idea. The development environment consists of (typically) a hardware definition language (#vhdl or #verilog), and a toolchain (usually vendor specific, though there are some open source ones) that synthesizes the code into a logic equation list. And finally a toolchain that takes that netlist and maps it into the individual small discrete functions and configures the routing between them.

There is volatile memory on the device that stores the current configuration and must be loaded (many ways) on power up. There are a few models that have non-volatile memory that stores the configuration and loads itself. In high radiation environments, there are even fewer (and very expensive) models that have write-once-non-volatile memory for configuration.

I don't think your idea of using them as a generic purpose drop in replacement for things is particularly a good idea. The board environment is honestly more important than what you're doing in logic.

Thank you for clarifying it for me. I am playing with the concept for now and - if I put my hands on an appropriate equipment - I may try to test the idea within some simple context. No pressure from me - ATM it is just something to give me a bit of mental distraction between one e-learning module I translate, and another.

The reason why #1 is resource intensive is because it relies on simulated annealing to determine which logic is performed on which logic blocks, to maximize performance within the design constraints. It's the same technique used in this video, for a different application. youtube.com/watch?v=Lq-Y7crQo4…

Importantly, all the resource-intensive part is happening in the toolchain's place-and-route algorithm. The HDL modules, and the conversion of them into gate-level logic, are cheap by comparison. From there, the toolchain has to fit that logic into whichever physical logic blocks are the best fit for timing, thermal, and pin constraints, by deciding where to place them on the die and how to route them together for a good-enough connection. Hence the name.

As for #2, those models are just what you get when you apply the resource-intensive algorithm to just a part of the final design, and treat that "solved" part as one big component to be placed and routed as a monolith. Although it takes less time when that part of the work is already done for you, it's also possible for that approach to produce a less-optimal solution on the FPGA.

Also, if you're using the same design across multiple chips of the same FPGA model, you can flash all of them with the same bitstream file generated from #1. You only have to do the resource-intensive part once.

...while a small percentage of human beings have lived in a wealth of food, material comfort and learning, those not so lucky have been the functional equivalent of domestic beasts, in harness to the powerful and well off, creating their wealth for them but not benefiting from it themselves. If you happen to be a young black farm girl, what can you say to the world, or the world to you? You exist under all four of the great inequalities, and will live a shortened life of ignorance, hunger and fear. Indeed, it only takes one of the great inequalities to create such conditions.
So it must be said that the majority of humans ever to have lived, have existed in conditions of immiseration and servitude to a small minority of wealthy and powerful people. For every emperor and bureaucrat, for every caliph and qadi, for every full rich life, there have been ten thousand of these stunted, wasted lives. Even if you grant a minimal definition of a full life, and say that the strength of spirit in people, and the solidarity among people, have given many and many of the world

Even if you grant a minimal definition of a full life, and say that the strength of spirit in people, and the solidarity among people, have given many and many of the world's poor and powerless a measure of happiness and achievement amidst their struggle, still, there are so many who have lived lives destroyed by immiseration that it seems impossible to avoid concluding that there have been more lives wasted than fully lived.
All the world's various religions have attempted to explain or mitigate these inequalities, including Islam, which originated in the effort to create a realm in which all are equal; they have tried to justify the inequalities in this world. They all have failed; even Islam has failed; the Dar al Islam is as damaged by inequality as anywhere else. Indeed, I now think that the Indian and Chinese description of the afterlife, the system of the six lokas or realms of reality -- the devas, asuras, humans, beasts, pretas, and inhabitants of hell -- is in fact a metaphorical but precise description of this world and the inequalities that exist in it, with the devas sitting in luxury and judgment on the rest, the asuras fighting to keep the devas in their high position, the humans getting by as humans do, the beasts labouring as beasts do, the homeless preta suffering in fear at the edge of hell, and the inhabitants of hell enslaved to pure immiseration.
My feeling is that until the number of whole lives is greater than the number of shattered lives, we remain stuck in some kind of prehistory, unworthy of humanity's great spirit. History as a story worth telling will only begin when the whole lives outnumber the wasted ones. That means we have many generations to go before history begins. All the inequalities must end; all the surplus wealth must be equitably distributed. Until then we are still only some kind of gibbering monkey, and humanity, as we usually like to think of it, does not yet exist.
To put it in religious terms, we are still indeed in the bardo, waiting to be born.

Previously in 3dPrint Odyssey....

I completed installation of the #SpritePro extruder on the #CR-10v3 #Creality chassis.
Inevitable fallout made me replace faulty nozzle thermistor, made a cable bypass, move Y-axis endstop, replace inner fans with the silent ones and...

Today's challenge is the #hotbed indicator showing flat 144*C, real temperature notwithstanding.
I checked the hotbed #thermistor circuit and it gives ~104 kOhm(?) all the way down to the mainboard (#Creality 2.5.2. #ATMega).

The only reasonable conclusion is that it is the analog port problem. If it is broken, I probably have no choice but to replace the mainboard - unless...

My clever monkey brain sees a spare analog port on the board (the one marked "Thermistor 2" below).

Would it be possible to reassign it for the hotbed thermistor? I assume it may need a recompilation of the firmware, but what the heck: I can do it if I have to, opposite to buying a new mainboard for another 120 EUR I do not have...

To whom it may concern:

Od dwóch dni nie tylko wiem, że istnieje, ale też rozumiem, skąd się bierze i jak działa różnica (jedna z głównych różnic) w percepcji świata między „młodymi” i „starymi” umysłami. Co oznacza, że potrafię to wyjaśnić, jeśli ktoś byłby zainteresowany. Z przykładami z własnej (samo)obserwacji.

Oczywiście, to nie jest tak, że mój wgląd jest kompletny (w sensie wyjaśnienia wszystkiego) czy uniwersalny (w sensie odnośności do każdej osoby i kontekstu). Ale chyba na tyle istotny, że warto go dodać do mozaikowej mapy świata, którę każdx z nas nosi w sobie.

Chodzi otóż o czwarty wymiar. Jednym z podstawowych doświadczeń, dostępnych jedynie, gdy podmiot sam już przebył wyraźnie dostrzegany dystans w czasie, jest zmienność świata (a dokładniej jego elementów - zwłaszcza procesów) także w tym wymiarze. I nie chodzi tu o kataklizmy, destrukcję, czy inne widowiskowe efekty, ale o najzwyklejsze przechodzenie w przód (nie mylić z postępem!) w kolejne fazy funkcjonowania. Zmieniają się ludzie (w sensie dynamiki zewnętrznej - zachowań - i wewnętrznej - poglądów). Są też takie dynamiki i struktury, które podróżują wstecz - odmawiaj

Wielka Brytania doprowadziła do katastrofy mieszkaniowej. Idziemy jej śladem

Brytyjski model rynku mieszkaniowego jest bliźniaczo podobny do tego, który mamy i rozwijamy w Polsce. Z tą tylko różnicą, że działa dłużej, więc bardzo wyraźnie pokazuje, dokąd zmierzamy.

Trochę nie ufam temu artykułowi o tyle że w Szwajcarii jednak wiele mieszkań wynajmuje się od prywatnych właścicieli, głównie banków. Jest tu na pewno lepiej z niektórymi aspektami tego systemu, i mamy nawet ogólnokrajowy związek lokatorów, ale albo Galent nie wie o czym mówi, albo Zuryski rynek mieszkaniowy jest bardzo niereprezentatywny w skali całej Szwajcarii – nie szukałem mieszkań do wynajmu poza Zurychem, więc tak może faktycznie być.
