6.1.8.2. Address Span Extender Parameters
Parameter | Description |
---|---|
Datapath Width |
Width of write data and read data signals. |
Expanded Master Byte Address Width |
Width of the host byte address port. That is, the address span size of all the downstream agents that attach to the address span extender. |
Slave Word Address Width |
Width of the agent word address port. That is, the address span size of the downstream agents that the upstream host accesses. |
Burstcount Width |
Burst count port width of the downstream agent and the upstream host that attach to the address span extender. |
Number of sub-windows |
The agent port can represent one or more windows in the host address span. You can subdivide the agent address span into N equal spans in N sub-windows. A remapping register in the CSR agent represents each sub-window, and configures the base address that each sub-window remaps to. The address span extender replaces the upper bits of the address with the stored index value in the remapping register before the host initiates a transaction. |
Enable Slave Control Port |
Dictates run-time control over the sub-window indexes. If you can define static re-mappings that do not need any change, you do not need to enable this CSR agent. |
Maximum Pending Reads |
Sets the bridge agent's maximumPendingReadTransactions property. In certain system configurations, you must increase this value to improve performance. This value usually aligns with the properties of the downstream agents that you attach to this bridge. |
