Modular CPU acceleration card solves problems in most advanced datalogging

Embedded electronics specialist Xylon is currently at the production stage with its new CPU acceleration module that solves different datalogging challenges in high-end ADAS and autonomous systems. Upcoming automotive systems use numerous smart sensors that produce different kinds of raw and preprocessed multichannel data, which makes precise and reliable datalogging extremely challenging.

Besides generating video, smart cameras also generate data on detected objects, projected trajectories, diagnostics and similar heterogeneous data that must be decoded in real time and displayed during test drives. This requires dedicated powerful processing resources. Xylon’s new module provides this with the integrated CPU with two FPGA companion chips. The FPGA chips significantly expand standard CPU capabilities.

The new card offers a rich choice of communication channels. 10Gb input and output, supported by implemented Data Distribution Service network middleware, enables direct datalogging from popular automotive AI platforms that multiplex all sensory data on a single Ethernet channel. Convenient auxiliary 2x USB 3.1 interfaces support new GPS modules, dash and reference H.264 cameras and the recorded data offload.

One of the most important new capabilities is full datalogging support for reference Ethernet surveillance cameras, such as the Real Time Streaming Protocol and GigE Vision cameras. Due to H.264 or H.265 video compression, video output from such cameras inherits the frame jitter that makes timestamping

imprecise. Xylon has solved this industry-wide problem by using custom HW accelerators implemented in FPGA companion chips.

The list of new features enabled by extended computing capabilities goes on. The new CPU module also enables the Universal Measurement and Calibration Protocol (XCP) master mode on CAN and Ethernet networks, as well as the AUTOSAR Scalable Service-Oriented MiddlewarE over IP (SOME/IP) Ethernet communication protocol. Based on future needs, Xylon will be expanding its software support.

The CPU card is modular and has three slots for additional Ethernet network modules of the customer’s choice that can be easily plugged into the box. Xylon offers the 100BASE-T1, 1,000BASE-T1 and 2.5GBASE-T automotive Ethernet modules, as well as the 1,000BASE-T Ethernet module. All modules support PTP/gPTP time synchronization and provide four channels that can be used either directly or in a two-channel network TAP configuration. According to Xylon, minimal possible latencies of the Ethernet TAPs make this hardware solution unique on the market.

The new CPU acceleration card will be integrated into the next iteration of the third-generation logiRECORDER Automotive HIL Video Logger. Full system availability is planned for Q4, 2022.
