| zyp | oter_, I would assume the address is a direct offset into the ram; a 25 bit address for a 128 bit word can address 512MB | 00:53 |
|---|---|---|
| zyp | to translate addr from a normal byte address to a 25-bit DMA address, I figure you'd do something like addr[4:29] | 00:55 |
| zyp | i.e. you're not interested in the lowest four bits, since you're adressing a whole 128 bit word, and you're also not interested in the top three bits since that's just the dram offset on the main bus | 00:57 |

| zyp | translating the other way you'd append four zero bits on the LSB end and the offset bits on the MSB end | 00:58 |

| oter | Thanks a ton, zyp! | 02:08 |
| oter | no dice (yet) - am not getting the value I wrote to the 0-offset rambase if I just supply 0 as the DMA read address - must be doing something else wrong in the handshake. I' | 02:26 |
| oter | l'll keep digging in 2021 :-). | 02:26 |
