AXI Bus Extender IP Core

AMBA AXI from ARM Holdings is an high performance on-chip bus architecture. Wide datapath versions of of the AXI are not amenable to extensions beyond a single chip/FPGA. Flowgic's AXI Bus Extender(ABE) core makes it possible to extend AXI bus across two chips with very few package pins. ABE core is built using Flowgic's Interlaken Controller(IL) core, which is a flexible, high-bandwidth, packet transport mechanism for chip-to-chip communication

Key Features

  • Supports 64-bit and 128-bit AXIdata channels
  • Transparently bridges transactions, maintaining AXI ordering requirements
  • Makes use of Interlaken controller, a flexible and robust, chip-to-chip packet communication protocol controller
  • Maps AXI channels to independent Interlaken channels
  • Provides an additional high-priority external message channel to user logic for communicating control and status information
  • Dedicated high-priority internal message channel for Heartbeat and health status reporting
  • Built-in arbiter that accords highest priority to message channels and round-robin arbitration for AXI channels
  • Simple, synchronous interface to user logic
  • High-speed SERDES lanes or lower-speed LVDS lanes for chip-to-chip interface
  • Extensive error reporting and diagnostics
