1394 and AS5643 IP Core solutions - FireGate

FireGate IEEE-1394b
PHY layer Core

FireGate is a synthesizable IEEE-1394-2008 Beta PHY core and is architected to support data rates of S100 through S3200. It is fully IEEE-1394b compliant and supports all AS5643 requirements.

Design features and benefits

There are several advantages when using FPGAs to implement a complete 1394 I/O interface. Some of these are:

  • Standalone solution: The PHY IP can be combined with Link Layer IPs, creating smaller, compact solutions. Additional components can be added to create a System-On-Chip (SOC) solution.
  • Flexible number of ports: Commercially available PHY chips have a fixed number of ports which for small peripherals is often overkill. On the other hand, host adapters would likely benefit from 3 or more ports and a hub could even have more than that. For a PHY based on FPGA technology, the user can customize the number of ports as required.
  • Optional debug and test features: Optionally the user can include debug and test features like BERT (Bit Error Rate Test) Low level data monitoring and Recording
  • Field-upgradable: The used FPGAs are field upgradable thus allowing the addition new features or bug fixes, even if the device is already in the field.
  • Cost effective ASICS: Once a design is finalized an IP solution offers a very cost effective path to spinning a custom ASIC. 

Key features

  • Complete IP solution supporting IEEE-1394b-2008 and AS5643
  • Support for speeds from S100 to S3200 *
    • Single-Speed Support (S100, S200, S400, ...)
    • Multi-Speed Support (S100 - S400, S800 - S3200)

FireGate Details


FireGate presents a fully IEEE-1394b-2008 compliant PHY Layer implementation. The main PHY layer related functional blocks ensure functional standards compliance as well as interoperability with off-the-shelf physical layer devices. The PHY/Link layer interface has been optimized for performance and deviates from the standardized PHY/LLC interface. FireGate is optimized to work with FireLink which also supports these enhancements. FireGate was not designed to be paired with off-the-shelf Link layer devices; it is intended to be used with FireLink or a custom Link Layer implementation.

A key element of FireGate is its configurable PHY front end, i.e. the ability to customize several aspects of the PHY cable environment interface. During the configuration phase the total number of available PHY ports can be adjusted (max 16) and as well as the total number of PHY instances per FPGA device. Furthermore, the speeds supported by the PHY can be defined. The PHY speeds can be either predefined to support single network speeds (for example S100, S200, S400, ...). This reduces network speed negotiation times (only applicable if the entire network would use the same PHY). Alternatively, the PHY(s) can be configured to support speed ranges (e.g. S200 - S800) and limit the speed negotiation to those values).

Additionally, the PHY also contains patented improvements over standard 1394 implementations. DapTechnology has been one of the very first companies to actively advocate such functionalities within PHY devices.
