Hello and congratulations for your project!
I am an EE with some experience to digital electronics but no experience to FPGAs.
As a project to start learning fpgs design i plan to recreate the snes APU.
(The reason for this particular chipset, is because i like snes music :))

My question is how do i start (besides the obvious learn Verilog/VHDL)?
I mean how this chip was exposed to the community in the first place? Was decapping and imaging used?
How did you approached writing your APU core?

Much of the APU information would have first been obtained or leaked from development documents and more information probably became available due to emulation projects. No decapping involved. If you want to create a SNES APU in a FPGA perhaps cloning the CPU of the APU module would be the first logical step.

Seems to me this project is dead.

I think you mean "this project is done" :p

Sure, I know you meant "can I buy it" but that wasn't explicitly ever something that was being offered.

And, from an external view, it seems to be quite close to finished, if not actually finished.

Hello all!

Yes, I'm still alive. :) Actually...maybe too alive... The popularity of my work on the SNES has had the unintended and totally unexpected consequence of generating more contracting requests for my embedded system consulting business. We were already overloaded with requests but I've been completely overwhelmed for the last several months trying to figure out how to handle the influx of design/consulting jobs. I finally broke down and hired two additional contractors just to keep the business above water - I originally wanted to avoid this because my consulting business was never meant to be this much of a time sink, rather just some fun side work for me and a couple other friends.

It's been a crazy time as a result and on top of that one of my family members had a medical issue which wreaked all kinds of havoc in mine and my wife's schedules. On top of that my wife and I have also been in the process of negotiating a new lease agreement so we can move her private practice to a new location. Needless to say it's been a whirl wind and the last several months are mostly just a blur. 0.o

So, sorry to keep you guys in limbo. I'm hoping to get back to SNES/retro stuff in the very near future. Things are finally starting to settle down............................I hope. :roll:

Cya!

EDIT: One other thing I had wanted to mention (that I thought was kind of humorous) was that some folks at my primary job requested that I make a software emulator version of this new neuromorphic processor architecture that I designed (semi-,kinda-,sortof-related to this other project I worked on viewtopic.php?f=5&t=14821). They primarily want the emulator because the FPGA hardware required to run the real deal is incredibly expensive and an ASIC implementation is still in the works.
When I first started working on emulation over a decade ago I never thought it would end up filling my every waking hour! :shock:
