Re: Gigatron ASIC?!?

If this is truly going to be an iterative process with multiple opportunities to add USB at a later date, we could do w/o USB first time through, but no NVM seems like a show stopper. Maybe just have it be a 64kx16 SRAM that loads via SPI each power-up? Coming up with an NVM compiler for this ASIC'...

Re: Gigatron ASIC?!?

So each of the chips comes with a RISC-V on board which is part of the standard harness that efabless would design, so I'm more confident in your ability to port Babelfish over to the RISC-V and do away with the Arduino all together than I am in my ability to slap on an AVR core from Opencores and ...

Code: Select all

./gtRun.py blaknite/puzzles
That sounds like a great idea!

Re: Gigatron ASIC?!?

This is a fantastic idea, I personally have no ASIC experience and my FPGA experience is starting to get rusty; but whatever I can help with I'm available to try and make this a reality. All the extra features you mentioned sound great to me, the only thing I would add, (seeing as this is effectivel...

Re: vCPU instruction frequency

And yes, the "pixel burst" OUT instruction (superimposing the first two bits for the sync and incrementing X to pass to next pixel) is by far the most used, since the gigatron is spending most of his time generating the physical VGA signal! Regarding the comparison will be very easy: I've...

Re: Raspberry pi loader

Hi, everyone! I feel like I've joined so late in the game on all this fun! I finally got my Gigatron put together (felt like quite an accomplishment for me since when I started, I didn't even know how to solder! lol) Welcome and congratulations on getting the Gigatron up and running; it really is a...

Re: vCPU instruction frequency

It's extremely interesting actually, as PucMon's code was generated by a compiler and it's fascinating to see where the hot-spots are. What would be even more interesting would be to compare compiler generated vCPU to hand generated vCPU. DavidHK did something similar, but at the native instruction ...
