The 36-bit physical address map of the adaptable P3041 is divided into local space and external address space. 32 local access windows (LAWs) within the local 36-bit (64-Gbyte) address space define mapping for the local address map. The P3041 can be mapped into a bigger system address space, like the RapidIO or PCIe 64-bit address environment, using inbound and outgoing translation windows. The address translation and mapping units have this capability (ATMUs).
