Assembly ID
Assembly ID
corresponds to the ASSY_ID field of the Assembly Identity register
(
), 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 (
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 (
) 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
—instead of the PROCESSOR bit.
Switch Support
The Switch Support options define switch support characteristics.
