RDRAM Interface
The RDRAM Interface (or RI) act as a controller of the RDRAM channel to which one or more RDRAM modules are daisy-chained. It converts memory accesses from the system into RDRAM protocol commands, to which RDRAM modules responds.
The memory area devoted to RDRAM Interface and RDRAM modules is divided as follow :
| Address Range | Name | Description | |
|---|---|---|---|
| 0x0000 0000 | 0x03EF FFFF | RDRAM memory | Allows to access RDRAM memory of configured module |
| 0x03F0 0000 | 0x03FF FFFF | RDRAM registers | Allows to access RDRAM register of configured module |
| 0x0470 0000 | 0x047F FFFF | RI registers | Allows to configure RDRAM Interface behavior |
