Contact Provider Request Datasheet

Overview

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

A comparison of Network-on-Chip and Busses

This whitepaper summarizes the limitations of traditional bus-based approaches, introduces the advantages of the generic concept of NoC, and provides specific data about Arteris’ NoC, the first commercial implementation of such architectures

IP Core for an H.264 Decoder SoC

This paper presents the development of an IP core for an H.264 decoder. This state-of-the-art video compression standard contributes to reduce the huge demand for bandwidth and storage of multimedia applications. The IP is CoreConnect compliant and implements the modules with high performance constraints.
