IP Module - 1394b OHCI Link Layer IP Core

The New Wave Design and Verification (New Wave DV) 1394b OHCI core provides a complete IP solution for the OHCI layer of the 1394b AS5643 support protocol.

The 1394b OHCI core includes all functionality needed to meet AS5643 performance specifications, including: Asynchronous Transmit, Isochronous Receive, STOF handling, STOF regulated transmit functions, Self ID, and CRC generation/checking.

At the PHY-Link interface, the 1394b OHCI core is built for connecting to any PHY that implements the defined standard PHY-Link interface. This interface is compatible with the New Wave DV PHY IP 1394b OHCI core as well as discrete PHY Layer integrated circuits.

1394b OHCI core meets AS5643 support protocol, and comes with test-benches and example code, making design integration a straightforward task

Key Features:

• AS5643 compliant interface with hardware based STOF offload
• Supports S100/S200/S400/S800/S1600/S3200 data rates
• Configurable number of OHCI nodes in a single FPGA
• AXI-based host interface for embedded or PCIe based processors
• Standard PHY-Link interface

Supported Devices:

• SmartFusion2
• IGLOO2
