Version

2.1 English

Common Configuration:

Connectivity Mode: Shared-Address/Shared-Data (SASD, as selected by Minimize Area strategy)
Protocol: AXI4 or AXI3
Data Width: 64 or 512 (as noted)
Read/Write Connectivity: all SI and MI read/write
Thread ID Width: 0 (all SI)
Address Width: Global = 32; per MI = 16-bit address segment (1 address range)
Arbitration Priority: 0 (round-robin)
User Widths: 0

Note: The specifications in these tables are derived by implementing the configured IP in isolation, characterizing clock frequency based on static timing results, and then applying a 10% guardband below the highest constrained clock frequency that meets timing.
