The local memory maps for the RPU CPUs include:
- Local TCM and cache memory map
- Local interrupt control memory map
The CPUs have direct access to this memory space without a protection unit.
The memory map from the CPU's point of view and a view from system-level processors is shown in the following table.
| Memory Type | Size (KB) | Dual Processor Mode | Lock-Step Mode | |||
|---|---|---|---|---|---|---|
