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.

FLOW_CONTRO

 

PE supports congestion flow control mechanism

 

L_SUPPORT

 

 

 

 

0b

PE does not support flow control

 

 

1b

PE supports flow control

6

RETRANSMIT_S

 

PE supports suppression of error recovery on packet CRC errors.

 

UPPRESS

 

 

 

 

0b

PE does not support suppression

 

 

1b

PE supports suppression

5

CRF_SUPPORT

 

This bit indicates PE support for the Critical Request Flow (CRF) Function.

 

 

0b

1b

PE supports CRF Function

4

LARGE_SUPPO

 

Support of common transport large systems.

 

RT

 

 

 

 

0b

PE does not support common transport large systems

 

 

1b

PE supports common transport large systems

3

EXTENDED_FEA

 

PE has extended features list; the extended features pointer is valid.

 

TURES

 

 

2-0

EXTENDED_ADD

 

Indicates the number address bits supported by the PE both as a source and target of an operation.

 

RESSING_SUPP

 

All PEs shall at minimum support 34 bit addresses. Encodings other than below are reserved.

 

ORT

 

 

 

 

111b

PE supports 66, 50 and 34 bit addresses

 

 

101b

PE supports 66 and 34 bit addresses

 

 

011b

PE supports 50 and 34 bit addresses

 

 

001b

PE supports 34 bit addresses
