1394b OHCI Link Layer 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.
The 1394b OHCI core is targeted towards applications in aerospace and industrial vision, and has been used on a wide range of parts at varying operating rates. Additionally, the 1394b OHCI core meets AS5643 support protocol, and comes with test-benches and example code, making design integration a straightforward task.
Evaluation versions of the 1394b OHCI IP core, with AS5643 performance protocol are available. In addition, New Wave DV has a set of standard form-factor boards featuring FPGAs, 1394b connectors and transformers, and off-the-shelf reference designs for quick evaluation of the OHCI IP core.
