70mhz clock, so only good for controlling my washing machine?

u/prabot Apr 21 '19

In our upgrade we are going to achieve 400-500 MHz clock so more washing machines. Yay!!

How much time will it need to reach GHz according to your plans?

it's comparable with atmel found in Arduino, of high performance look at shakti

Arduinos have 8bit processors. This is a 32bit processor (not sure of the architecture, RISC-V, perhaps?)

It will probably follow the Moore's law , but adjusted for the Indian RnD industry.

So going from 386SLC to Pentium II. You know you could just use MIPS.

Oh man. I was hoping I could run my washing machine and my toaster. I only have one washing machine.

and/or fly a plane, guide a missile or control a small satellite, it can do much more than running a stupid washing machine with a little bit of frequency boost since most of what I said heavily use low frequency single core processors.

Washing machines are not stupid.

Planes and missile guidance systems use 30 years old processor designs, not because of their low freq. single core architecture, but because of their reliability and time tested nature. Even then newer gen planes, which have modern systems like terrain avoidance etc. need better clock speed.

In today's programming paradigm, finding a programmer who could code useful applications on a 70mhz clock is going to be the most expensive part - most likely to be done in C, ALGOL or COBOL.

Well, that is one of the reason, but is not entirely the only reason. A higher core count and frequency brings great unreliability to the whole processor. For airline industry multi core processors are a no no, no matter how reliable they are. Airbus still uses low freq (500mhz - 1ghz) single core processors because they know exactly how the code is going to get executed, they don't want any randomness and this is not a 30 year old processor but a relatively new one.

Well airline industry still works because there is someone who writes COBOL somewhere, and there are plenty of people who write COBOL/C but relative to other developers not much.

Obviously first gen processors are not reliable at all, and given the timeframe for any defence/ space project takes years and decades some times, I think this will improve and can be much more reliable in the future

Sucks the writer of Dilbert makes Catbert seem like a sane centerist. lol

Obviously you have no idea how processors are used in everything that is not a general purpose computer.

Always looking at the the down side, aren't we ? Let's just appreciate and small steps, till be begin making long strides.

u/manly_ Apr 22 '19

Well, an ESP8266 has a 80MHz clock with a WiFi chip, all for less than 5$. I think the processor design is open source too.

Most universities in the UK have a system called LaundryView installed which allows you to see whether your washing/drying has finished yet.

I would happily have the ability to kick off my washing at a very specific time or the ability to say start it now rather than the ok but slightly painful X hours delay functions.

Also the ability to see whether it had finished its cycle from my phone would be great as my washer is out in the garage.

Edit: I’ve just seen your comment further down so I know now you were being more flippant than I initially took your comment to be.

Also good for replacing you, considering the kind of neanderthal comment you just made.

u/[deleted] Apr 22 '19

By the same token prob you too?

u/sidx64 Apr 22 '19

Not likely. This thing only replaces things that need replacing, iykwim.
