MiniMig with AGA

[bloodline]

Looks a bit like ADA

Apparently that's what it was based on :-/ I've been looking over various VHDL tutorials for the last 15min and nothing is grabbing me... I think I'm just so ¨C¨ ingrained now... I can basically make sense of the listings, but I can't visualize it

[bloodline]

* VHDL, tough!, you have to eat shit initially but you can do the bit-flank-bang any way you want in the end. Get used to Cobol fingers(tm). Modeled after ADA thanks to DoD .. Doh!..

* Verilog, Modeled on the C language, Shoot from the hip! Fast way to bit-flank-bang heaven with limitations in advanced level.

Then there's the C++/C whatever to VHDL/Verilog translator. BUT interpreting programming languages is the wrong tool for the job. A shortcut that can make you suffer the brick wall.

Ok, yeah a few min with Varilog and stuff it making MUCH more sense...

@Franko

I've just read through the Verilog 1 Day tutorial and it all seems to make sense, it's very C like except with concurrency... I don't know how one begins with VHDL though...

[bloodline]

Damn fine work by all involved, then

Alright, I'll rephrase my statement... TWO guys in their bedrooms built a better CPU than Motorola's entire CPU dev team in the whole 80's...

Out of curiosity I downloaded the VHDL source for the TG68K. My first reaction was, "Is that it? It's so small!"

When you consider the size of your typical software emulation implementation, it looks dinky

I think the fact that the languages have defined microblocks ( I think I'm using the term properly) for basic operations (arithmetic, logic, data moving), these things have been preoptimised for performance. All one really needs to do in the TG68 core is decode the instruction, set the flags and pin signals correctly etc... Not to say that this isn't a huge achievement, just that the boring shuffling of bits is handled at a lower level, which saves a lot of space.


The whole tone of this post sounds negative and wrong... Try and reread it with a smile, as it's supposed to sound positive and excited...

Probably most people are able now to make a car in their garage that performs better than the early Ford (or Citroen deux-chevaux for the Europeans) in their garage. This does not mean that the original work was not a magnificent peace of engineering.

greets,
Staf.

Hey Staf, I was not being serious in my post. The FPGA tools do a lot of the hard implementation work that simply had to be done by hand in the 80s... Also it's easier to build something that you know is going to work as it's based on a preexisitng idea, than to build something from scratch

[bloodline]

Viewed in those terms, so does any software implementation. You know, things like data move, logic and arithmetic tend to have operators in C

Exactly! C v's ASM

:lol:

I know, sometimes I basically suck...

[bloodline]

My word this looks sexy!

All those years of PL-SQL and Turbo Pascal are flooding back to me.

Ada is nice!

ADA... and there was Karlos mocking my contentment with Obj-C!!

[bloodline]

heheh

We all have our deviancies I guess Matt!

You're lucky that you'll only get it on tha interwebs, I'll have to put up with his mockery in person quite often! :/

Don't be so sure, the interwebs are a positive haven from the torment of the real world... but I bring it upon myself as someone not necessarily wishing to conform.

[bloodline]

:roflmao:

I think you're trying to tell me something... I just can't quite put my finger on it...

[bloodline]

Who knows what sort of thing they get up to in "that London"?

The very reason I moved here 11 years ago

It's hard to feed any perversions on the Isle of Wight

[bloodline]

Unless one is a paedo.... or was that Jersey or Guernsey?

Yeah, Jersey.

[bloodline]

On a more related note,  I've dug out my RKRM's and various 68k books to get the old synapses firing in nostalgia mode.

AROS 68k source here we come.

Well, that's the point of AROS! Shame others don't get get stuck in and have some fun!

This VHDL stuff is looking very tempting though, anyone suggest a first-timers FPGA kit to buy or perhaps shuld I just get one of MikeJ's boards?

I think MikeJ's board is probably the best option... that way, if you find yourself totally stumped and bored with VHDL... at least you will have a new Amiga...

[bloodline]

MikeJ's board does look rather tempting, moe tempting than a MorphOS licence key for my Christmas pressie (If you are reading this love!)

I'm not getting you a Replay...

[bloodline]

loooooooooooooool

Go on, I'll show you round Maida Vale Islamic Centre if you do.

Kind offer, though I expect I'd get about as much out of the visit as you would from one of Dawkins more boring lectures... :lol:

[bloodline]

Oh it's a beautiful building Matt, Grade A listed.

Much nicer than Finsbury or Regents Park I might add too and no one will try to kill you for being a "filthy infidel" either! :lol:

Only Finsbury park mosque is horrible, mind... But the whole area is a horrible place.

I love Dawkins lectures, or should I say I like rebutting his points.

I think he'd actually like that!
