Table 98. Processing Element Features CAR (PE_FEAT) Field Descriptions
Bit Field Value Description
31 BRIDGE PE can bridge to another interface. Examples are PCI, proprietary processor buses, DRAM, etc.
30 MEMORY PE has physically addressable local address space and can be accessed as an endpoint through
non-maintenance (i.e., non-coherent read and write) operations. This local address space may be
limited to local configuration Registers, or could be on-chip SRAM, etc.
29 PROCESSOR PE physically contains a local processor or similar device that executes code. A device that bridges
to an interface that connects to a processor does not count (see bit 31).
28 SWITCH PE can bridge to another external RapidIO interface- an internal port to a local endpoint does not
count as a switch port. For example, a device with two RapidIO ports and a local endpoint is a two
port switch, not a three port switch, regardless of the internal architecture.
