AXI Crossbar Performance: SAMD, AXI4 Protocol - 2.1 English - PG059

AXI Interconnect LogiCORE IP Product Guide (PG059)

Document ID
PG059
Release Date
2025-12-19
Version
2.1 English

Common Configuration:

  • Connectivity Mode: Shared-Address/Multiple-Data (SAMD, as selected by Maximize Performance strategy)
  • Protocol: AXI4 or AXI3
  • Data Width: 64 or 512 (as noted)
  • Read/Write Connectivity: all MI fully connected for read and write
  • Thread ID Width: 0 (all SI)
  • Address Width: Global = 32; per MI = 16-bit address segment (1 address range)
  • Read/write Acceptance: 4
  • Read/write Issuing: 8
  • 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.
