REV 3 - REV 5 - The beginning (ST536)

But nothing seems to have changed speed wise.

Are you sure you're decoding the access? (AS_MOBO versus AS_030)

I figure it out. I was using AS as a input, and it was only declared as a output :roll: It was screwing up my ROM decoding logic.

So now the "proper" results with blitter:

So blitter is actually faster.. But "worthwhile faster" maybe not so much.

Still pretty interesting that a 50Mhz CPU with caches and all sorts of speed up hacks only just keeps up with the 8MHz blitter in most tests :lol:

Well done!

Personally, I'd say it was worth it if it were a costless exercise, but you'd now need to have a separate STE firmware (or perhaps a register to turn this on?) that doesn't assert DTACK. Not sure there's a net benefit to you as a seller in that case.

I am not sure that DTACK would matter though ? I have not checked, but I assume that DTACK on the STE goes low about 20-40ns after /AS low. My DTACK will go low after about 30ns.. Even so these are open collector things, so even if both go low or one or the other it does not matter. Also, everything is still running at stock speeds anyway at that point. So any bus master doesn't care about the timing.

I'll bow to your superior knowledge of the glue logic on the ST boards -- but are you 100% sure DTACK is only ever driven open drain by the motherboard? If so, then yeah, it should be safe.

Nothing *should* drive it high. If it does, then another suckage of the system I guess. But even so, any chips doing so, should/could only be doing it when it has its own CS signal asserted ? If something is driving DTACK high otherwise, then I don't see how the system could ever even work.

At worst it could only be if AS=1 then DTACK=1. At which point we don't care anyway ? If DTACK is still driving high when /AS goes low, then that would be shorting stuff out "from stock". I don't think thats the case as DTACK generally goes low 20-40ns after /AS goes low. My timing doesn't issue it right away, it would still be at least 30ns. So it would pretty much match the chipset timing anyway.

I would have course be very interested if you or anyone else for that matter has evidence to show that some chip on the board is driving DTACK high rather than using the proper method of open collector. I know people have over the years have suggested exactly the same but I have never seen anyone actually ever prove it.

Wow nice, well done on getting the blitter working!

MFP's DTACK is not open drain, it is tri-state active push pull. Which means it might drive actively high for a short time, but, of course, only while selected.

So what happens on the STE if nothing issues DTACK after (I think it's about) 100 cycles, BERR is issued.
Blitter doesn't care whether it's DTACK or BERR it just sees end of cycle and carries on. So ends up running ~50x slower than normal. I presume it's the same on the STF chipset.

GLUE asserts BERR after 64 cycles. This is the same in the STF or the STE.

EDIT: Fixed typo at BERR

Good to know thanks.

Having right problems getting it all to FIT :roll:

A 288..

Capture.PNG

143 Macrocells used.. And yet it does not fit with a 144 marcrocell device :roll: I have tried all the optimisation options even going to ignoring the pinout still cannot do it. Even taking out various chunks of code still does not fit.

I think I had similar problems with the ATF chips. Where it seems to run out of, I assume, internal wiring space. But you would think taking out thing like the alt-ram decoding line would save a bit of routing.. but makes no odds.

I could have done the extra code in gates as previously mentioned, but now that I have added in yet another line with DTACK.. I don't think it stands a chance of fitting.. But this thing is so incredibly close anyway... :roll:

EDIT:
This has to be a bug surley ?!

Code: Select all

ERROR:Cpld:837 - Insufficient number of macrocells. The design needs at least
   581 but only 144 left after allocating other resources.

Not sure if something is getting stuck in a loop here ?!
