FPGA Replay Board

[wawrzon]

Hehe...How fast minimig do we need :-) I am just glad to hear RTG is in the pipeline so that we can glue the Replay board to the back of a monsterous Apple 24" screen and thus use the Replay board as a kick ass Classic usage with workbench and super-speed and a nice resolution. I believe Mike or Yaqube mentioned that 1680x 1050 should be possible to produce. That's gonna be very nice... :-)

should not be a problem if it comes to amiga68k rtg solutions, my main 4000er handles that alright even under p96. cant use the (expensive&shitty/4.2 dumb users) mac display i have standing here cause it doesnt accept analogue signals anymore.

[wawrzon]

may we see some benchmark please?

[wawrzon]

ok according to sysinfo it is only 7.7777777777.. slower than 060/100
(if so it needs to be about 4 times fater to catch up with 060/50)

[wawrzon]

And the one you designed is how fast again?  

Why do people have to be so negative about positive things...

It's not Natami.  It is as fast as it was designed to be...

I'm happy with that..

you think this comparison looks bad for the fpga arcade (especially the softcore is still wip) and i was going to bash it? i quoted a 060/100 (there is only one such yet to my knowledge) and a regular 060/50, which is the fastest official reference amiga hardware there is. which means the softcore could have yet a realistic chance to catch up with 060 given some improvements. which in turn may support the theory that natami core could in fact be even faster. good things are going on. why do you people always try to assume an intended insult is beyond me.

Amigadave,

I fully expect to increase the performance of the internal CPU as well.

thats what i expect as well. thanks.
aros 68k is progressing well so i think soon there is an kickstart replacement for everyday use. even if 100% compatibility is a tough goal.

[wawrzon]

i think the speed comparison is unpartial. depends what you read into it yourself, i think. tobiflex is also still working on his core, even if he admitted not to be so much motivated at times. bitfield instructions are being implemented.

[wawrzon]

i think the bounty has already been approved complete, which doesnt mean you can run just any 68k application fine. this will be ongoing work for yet some time.

[wawrzon]

you can download the nightly and throw it at your winuae to see for youreself how far things are working already.

[wawrzon]

trivialities like pushing windows outside the screeen are standard on aros(68k), on aos you have to use powerwindows for that (a very good patch). directories open within a browser window with a back gadget, which is more convinient than the way workbench does it. still there sre some behaviour disandvantages on wanderer. anyway i see aros as a replacement for well patched aos 3.9++ setup.

[wawrzon]

yes, the layout capabilities of wanderer have to improve. i for me hate for instance the cropped file names in the lister, the strict raster layout. the overall functionality is somewhat worse than workbench at this time. but i hope it will be fixed. deadwood works already on optimizing decoration.

[wawrzon]

my mockup would come close to what 3.1 had to offer plus some extras like above mentioned pushing windows off screen and easy extention for custom menus. wouldnt even need any kitchy dock in such a case. the icon style could remain inline with magic workbench standards if you ask me, with ability to display hiher color ones on deeper screens and color reduced copies down to one plane black and white desktop like mac once had. when ive done planar gadgets for afa i experimented with like 1650x1080 1 plane black and white workbench setting and i must admit, it looked kinda cool for me.

[wawrzon]

@digiflip: seems you are really a little over the top here.

[wawrzon]

even though im genuinely interested i m not sure if im going to invest in another amiga-compatible system any soon, especially id need 060 expansion to have it justified beyond what i already have. i hope though, it will be soon available in greater numbers and will encourage  at least some developers from our divided camps to look back at 68k (and aros68k) with little more interest again.

i remember majsta on natami forum saying hes gonna look at alternative cores suspecting they might be a better hoice. what cores, he didnt mention.

[wawrzon]

I haven't felt convinced that he ever did look elsewhere though. I really wanted him to look into some simulations of the TG68 he was looking at and compare that with simulations of the Suska's 68k block to help him understand what was so weird about the TG68 and help him figure out what to wrap around TG68 to make it work in a normal 68000 socket. I don't think I succeeded in getting him to run simulations either, or in convincing him of their utility or importance. (I'm a verification engineer of ARM SoC chips, and I think that part is tremendously important and useful for what he's trying to do so blindly) And he seemed to me that he absolutely must do it with TG68 and not anything else for some reason. I tried suggesting that he work with the already much closer to what he needed Suska 68k, see that work better much sooner to help him debug his board design, then go back to TG68 if he must, but he seemed adamant that he must complete his design using TG68 and must avoid others for some reason.

I very much like his idea, and look forward to his results, as well as whatever comes from the other guys.

I have some other cores in verilog that are faster but when I start working with them I ll tell you more. Also I have some papers Turkish authors regarding to Mc68K VHDL models and those papers are very interesting. Also there are some cores that are not public but I have them but didn't work with them yet. There was some talking about ao68000 who can work stable at 80Mhz.

sounds somewhat weird, and he doesnt seem very experienced, but looks like he actually wanted to look for alternatives. i think him being not a professional he might try to figure his way around that doesnt look reasonable to you, thats frequent with autodidacts..
