Btw,..  how much of the FPGA "space" is used currently?


Hopefully Mike will answer that one with regards to the updated core.

Wizard66 quoted this a while back:

Quote
Minimig FPGA: 400K gates
FPGAARCADE FPGA: 1600K gates
FPGAARCADE FPGA Full 60% minimig core+softcore (CPU).


So "currently" it uses 60% if the space including the softcore.  I guess the space uses by the softcore could be recoved if using the daughterboard with a real 68060.

mike mentions on his site about a guy wanting to sell the fpga arcade in a case assembled.Must be loriano pagni id say.This is the way i will go with this.Would the daughterboard fit in the case with the fpga arcade or would it be seperate.Pardon my ignorance.


Loriano has said that the daughterboard will fit in the case.

As you can see from this pic of the FPGA fitted with the daughterboard, it really doesn't add much to the overall height:


Worth noting are the 3 USB2.0 ports, the mini-SD card slot, 10/100 Ethernet, Optical Audio Out, an extra 128MB of RAM (in addition to the 64MB on the FPGA Aracde main board) and the RTC.  Drool!  ;)

Sorry I have been busy trying to gather the last bit of money (about £1800, more or less) to finish the case off...I am waiting for Mike to send me a board but if it's mini-itx and not higher than 54mm it should fit nicely.

I'd have the final prototype ready in a couple of weeks, hopefully in black.

Regards

Damn this is fine !
I might just stretch some more to get the daugtherboard as well.

i think the point with FPGA is to have it all in HDL-code such that one can tweak characteristics at will and share.

doesn't the 060 need a heatsink?  What kind of cooling is necessary in a unit like this?

A 060 wouldnt need a heatsink if its running at 50 mhz.

Man that is a sweet setup.. drooool

Shame it is running at 100MHz...  :D

Double drool!

What models of 060 runs with 100MHZ ? Any one ?

The EC models do, they were meant for imbedded devices like printers which have no need for FPU or MMU. Most commonly you see them for sale at 75 & 80 MHz

I was under the impression that Jakub's 100MHz CPU was a full 68060 just overclocked and still running stable.

So in essence the fpga arcade should be a more powerful a1200 with a high compatability rate.What percentage of compatability to old software should we expect.Will it be able to function as essentially a new and faster aga amiga computer? Also the other accelerator ram upgrade thingy project for the a500 looks sweet.Lots of cool miggy stuff about now.What to buy.With lorianos case+daughterboard+fpgaarcade this will be a wallet drought.

Correct, the final mask revision had greater timing margin and some chips can be run at >100MHz perfectly reliably.

We aim for 100% compatibility, but with additional features which can be enabled or disabled.
High resolution video out (DVI/HDMI), new audio DAC, USB, ethernet etc.
