Topic: Amiga FPGA accelerator
For some time I wanted to prove myself that I can design accelerator card around Cyclone V FPGA. It turned out that designing such card was very easy and not much different than designing card with Cyclone III. Only real difference was that I had to go with 6-layers PCB. It took me one month to do it and in September of 2017. everything was finished and prepared for testings. In this specific card I wanted to implement all knowledge gathered from previous designs. I wanted bridge between V2 models and upcoming V4 keeping SDRAM but adding Cyclone V as a base. Vampire 600 V3 code named V666 is born with 5CEFA4F23I8N or 5CEFA5F23I8N Cyclone V FPGA.
Some other components are added like DVI level shifter (PTN3360BBS) for better video out, much bigger flash is used (S25FL128SAGMFI011) and lot of expansions headers including new IDE header implemented from Vampire 500 V2+ model. There were number of fixes on microSD slot, SDRAM, power section. I have played also with silkscreen and soldermask and made card shine with red light provided by LED diodes. In general, performance of this card are not different than on V2 models and that's something I did expect. You can't get more as long you use SDRAM. Card was never planned for production and its purpose was purely as development card for the Apollo-team. This year on Alchimie 2018 card is presented and people started to talk about it on the forums so in this article I wanted to give more details.
More about the card from following pictures.
