4.1.5.4. Addressing and Memory Regions
CCU address map is categorized into three main spaces:
- Ncore register space (NRS)
- General-purpose address space (GPAS)
- Boot region (BR)
Each space may contain one or more address regions.
Address decoding is priority based. NRS has the highest priority followed by general purpose address space and lastly boot address space. If an access matches higher priority address space, then lower priority address space matches are ignored, and the higher priority space is selected for access. Within an address space multiple address region matches are treated as errors; this specifically applies to general purpose address space. An access results in an error if multiple address region matches are detected within a single address space or no matches are detected to any address space.
The CCU system address map configuration for Agilex™ 5 is defined according to the following table.
Area | Start Address | Offset |
---|---|---|
Ncore register space | 0x00_1C00_0000 | 0x0 |
Boot region | 0x0 | 0x0 |
DDR channels | Configurable through CSR | Configurable through CSR |
