Any way to hook up a processor?

Fri Jun 01, 2012 8:11 pm

Say I had an ivy bridge i7 processor lying around, is there any way to use it with the pi? Is there anything I can connect to the gpio that I can connect to the processor?

Not in any way that is useful. The GPIO just does not have enough bandwidth.
Maybe the DSI/CSI connectors can be used in the future as they have about 2Gbits/sec.raw throughput There are no GPU drivers for that (if ever...)

I'm trying to understand this question. So you have a Core i7 processor at around 3 GHz clock, uses about 50 W of power, and connects to a 1155 pin socket. No one uses such a part "bare", you connect it into its FCLGA1155 socket on a motherboard with big heatsink and power supply and memory- in which case you basically have a desktop PC. Probably this would talk to a R-Pi over a USB, Ethernet or serial link.

Yes there is. Buy a motherboard for the Ivy Bridge, then a PSU, some RAM and something to boot from. The 2 can now communicate via USB ^^

Processors like this require support circuitry (memory, io, clocks, etc) to do much of anything useful. I don't think there is enough gpio on the Pi to emulate all that. By the time you have all the of support stuff, you've got a motherboard, and by the time you've got that, you might as well have a full up computer. Even an older, simpler processor, like a Z80 or a 6502 (all the retro rage right now) would need more than the Pi gpio. Although hooking up a Pi to a full up computer wouldn't be bad, I don't think it would be entertaining for long. Or, at least it wouldn't be as interesting as hooking up to a micro-controller, like an AVR (Arduino), and the micro-controller doesn't need nearly as much support circuitry. Get the whole setup for less than $30.

Seems reasonable. But, that won't make the pi any "faster", right?

Hackery the only way the pi is going to be any faster is to ummmm make it not a pi. the pi is what it is. A low spec machine to give to a kid to play around with experiment on and not worry about busting it.

You are aware I presume that the PI has a processor ?! :twisted:

I just have to be a smart aleck here . There are actually multiple flavors of i7. 1366 pins. i7-9xx series. 1156 pins i7-8xx. 1155 pins i7-2/3xxx series and 2011 pins i7-38xx and 39xx series. And just because I 'm being a smart Aleck I looked it up and there are at leasrt three other sockets for i7 must be the laptop sockets. there are a ton of different ivy bridge CPU's running from 2.5 to 3.5GHz guess I am not that smart :lol:

I am with Obarthelemy put that sucker on a real mother board. hook the RasPi to it.! :twisted:

In a similar fashion I uncovered the following mod you can do with your RPi: if you afix it to the hood of a BMW M5 with duct tape it'll do 0-100k/h in under 5 seconds. It's up to you to decide whether it's worth the additional expense. For me it was a no-brainer.

Lame :P Clearly the proper upgrade would be to duct-tape it to a fighter jet, in order to have a supersonic-Pi :lol:
I haven't made any mobility-upgrades to my RPi yet though :(
