Hi
I'm looking into creating a rig using FGPAs.
To control them I would like to use a Beagleboard-xM or Pandaboard ES.
The Beagleboard-xM has a 1GHz ARM Cortex-A8.
The PandaBoard ES has a Dual-core ARM Cortex-A9 MPCore with Symmetric Multiprocessing (SMP) at 1.2 GHz each.
Has somebody used these boards?
How many FGPAs do you think it will able to manage?
Thanks.

The Bitcoin network protocol was designed to be extremely flexible. It can be used to create timed transactions, escrow transactions, multi-signature transactions, etc. The current features of the client only hint at what will be possible in the future.

Estimated hashes?  |

Estimated hashes? As a start 900 - 1000 MHash |

You really could use almost anything to control the FPGAs. For example, the Icarus board has simply a UART-USB chip. It takes USB data and feeds it serial into the FPGA. So the interface/control of the FPGA is trivial computing wise. The task is more about how you get work for the miner and UI/RPC.
I'm building a single chip PIC with Ethernet board as a miner control to feed a cluster of FPGAs. It's not built yet but the PCB design is done. I'm waiting for the Chinese PCB fab to re-open after their New Year so I can make some boards. Good they took a holiday as I'm having extra time to fix mistakes and improve the design.

I'm eager to get my hands on one when they come out. Credit card size coolness. |

Your DD-WRT'd USB router that would be really awesome if someone can get that to work. |

Well, got cgminer to compile for the mips (broadcom) processor my ASUS RT-N16 has. Absolutely no idea if it does ANYTHING, but it compiled! All in need to do now is: Actually install DD-WRT on my router. Acquire a BFL unit. See if it does anything |

Estimated hashes? As a start 900 - 1000 MHash WAT? how? on what board. Let's break this down. ps. The Raspberry Pi seems like it wouldn't hash much... But $25, I guess you can just buy LOTS of them. |

I think you missed it completely there n0ne. LMAO!
Hes wanting to use a Raspberry Pi to control a farm of FPGA's. The BFL's are supposed to get around 854 mHash.

haha yea maybe it went over my head. I'm a bit new to this FPGA stuff. The way I under stand it i RaspberryPi board with it's on-board chip would be way to weak. So I'm guessing the idea is to control something else with it? ps. I'm drunk, be nice  |

NA. I think it would be OK. Its a pretty powerful liittle arm processor.
All you really need is just something to distribute work to the BFL units, server as a "hub" and connect to your pool. All the hasing is done on the BFL (FPGA) in much the same context as a GPU does the work in a "normal" rig.

Oh ok I see. The idea is to use one of these to be the controller for all the BFL boxes. Neat, would make things more stream line. |

Unfortunately they are not for sale yet. But as soon as they are I will get myself one of these anyways. I think you missed it completely there n0ne. LMAO!

Exactly. This should manage several independant FPGA boards. BFL..., well let's see when they are out. |

I use a mini-itx atom D510MO as desktop and run my fpga from that, economical, silent and better for the environment and with proper linux!

The RaspberryPi is supposed to be around 5 watts. Most Mini-ITX boards will be in the 50 to 75 watt range. Oh, the RaspberryPi also runs a proper linux distro....Debian |

Im talking total power draw measured using a kill-a-watt. You figure in the ineffeciency of the PSU, HDD, and the mobo, you will see around 50 watts.
