DapTechnology's AS5643 interface card "FireTrac4x24bT" adopted in the F-35 project.

ナセル

There is a growing demand for more streamlined hardware systems for processing AS5643 data streams used for defense purposes. In particular, advanced error insertion capabilities are required for simulation purposes that cannot be achieved with commercial link layer implementations. FireTrac is designed to natively support AS5643 (not just as an add-on protocol). In addition to standard IEEE1394 functionality, FireTrac is designed to provide hardware-level support for SAE AS5643, particularly alleviating the burden on the host processor for tasks such as packet encapsulation, data extraction, and receive/transmit STOF offsets. Importantly, FireTrac is highly accurate as it handles AS5643 transmission timing entirely in hardware. Support for this protocol is built into the hardware and is not just a software layer, as is commonly provided by other solutions that rely on COTS OHCI chipsets.
