Assembly ID

Assembly ID

corresponds to the ASSY_ID field of the Assembly Identity register

(

Table 6–14

), which uniquely identifies the type of assembly. This field is assigned and

managed by the vendor specified in the ASSY_VENDOR_ID field of the Assembly
Identity

register.

Assembly Vendor ID

Assembly vendor ID

uniquely identifies the vendor who manufactured the assembly.

This value corresponds to the ASSY_VENDOR_ID field of the Assembly Identity register.

Assembly Revision ID

Assembly revision ID

indicates the revision level of the assembly and sets the

ASSY_REV

field of the Assembly Information CAR (

Table 6–15

).

Extended Features Pointer

Extended features pointer

points to the first entry in the extended feature list and

corresponds to the EXT_FEATURE_PTR in the Assembly Information CAR.

Processing Element Features

The Processing Element Features CAR (

Table 6–16 on page 6–12

) identifies the major

features of the processing element.

Bridge Support

Bridge support

, when turned on, sets the BRIDGE bit in the Processing Element

Features

CAR and indicates that this processing element can bridge to another

interface such as PCI Express, a proprietary processor bus such as Avalon-MM,
DRAM, or other interface.

Memory Access

Memory access

, when turned on, sets the MEMORY bit in the Processing Element

Features

CAR and indicates that the processing element has physically addressable

local address space that can be accessed as an endpoint through non-maintenance
operations. This local address space may be limited to local configuration registers, or
can be on-chip SRAM, or another memory device.

Processor Present

Processor present

, when turned on, sets the PROCESSOR bit in the Processing Element

Features

CAR and indicates that the processing element physically contains a local

processor such as the Nios

®

II embedded processor or similar device that executes

code. A device that bridges to an interface that connects to a processor should set the
BRIDGE

bit—as described in

“Bridge Support”

instead of the PROCESSOR bit.

Switch Support

The Switch Support options define switch support characteristics.
