FPGA-Based DSP Options

I'm afraid they will clone DX7s .
Copying an existing device in an FPGA is not really an exciting work.

I think I have said it before, the way we use the patcher to pass signals from LFO's, OSC, multiplexors, counter etc, and create logic references within the objects, seems very similar to how FPGA's are programmed.
Maybe there is something in all that... ?

[Gavin]

I guess what I am getting at, could the patcher or a version of it be used to program an FPGA. !!

Just saw a video from that Linus guy, you get to see an Open Source CPU already running games. He appears to think that these Open Source CPUs are due in our desktop PCs very soon, as in sooner than we think, so he's a bit more optimistic on the TOA than Mark and myself are, but I hope he's right cause it won't stop there, it automatically means true, fully Open Source tablets and phones too!

sure, just SMOP

Open Source CPUs are due in our desktop PCs very soon,

'mass' adoption is definitely a critical part of it - developers tend to support stuff once its available to large audiences, so something like this could take it out of niche.
( I guess it'll be he in high end/gaming pcs first?)

lets just hope if there are multiple forms that they are cross compatible or some kind of agreed standard - as lots of variations can hinder this.

btw: I think fgpa have been used before for emulation particularly for "vintage computers", I think they keep coming up in fact...
a quick google found this one, but I seem to remember quite a few for different computers.

FPGA-based Commodore 64 ‘Ultimate 64’ is now under production

Well I was hoping for some original design, like Neuron. Guess we have to wait and see

Very cool, and funny enough I did come across that project during the first version but I had no idea what an FPGA was and took no notice of the tech at the time. I just wish they'd get on with producing official Commodore branded enclosures to house them. Apparently a dutch firm has licenced the brand but I've not seen any official Commodore branded manufacturing of the cases etc yet.

Any work done keeping the C64 and Amiga alive are well worth it so I'm very pleased to see this stuff, definitely brings a smile to my face, which sadly these days is far too much a rarity!

But yup, very cool, FPGA effectively means eternal life for the C64 and Amiga

But than comes at a price > a lot of hard work, you have to build/code everything from ground.

Usually they are programmed from building blocks, down to entire CPU modules. The snag is that there is precious little of libraries that could be useful for us, bit-banging at GHz speeds is not really among the main problems of analogue synth emulations. If any, the ability to emulate already extinct digital chips could start a wave of virtual digital synths (emulated DX7 or Fairlight), or even virtual virtual analogues (say, a emulated Nord Modular).

To be honest I dont know that much of the details.

I just know that the FPGA code that I looked into didnt make alot of sense to me, hehe It seems to be a bit harder than just coding a little bit in the Axo editor.

I am open to anything new. So lets see where the FPGAs bring us, emulations or what have we
