THE SOLUTIONSOLUTION

Arilou CANpress extends the viability of current controller area networks (CAN). This software-only solution is designed to reduce network bandwidth utilization – extending the lifespan of current network architectures, preventing the need for, and expense of, migration to other technologies.

  • Compression

    Network capacity and performance improved by over 30%
  • High Performance

    Average message data reduction of 50%

Technologytechnology

Modern in-vehicle networks are becoming increasingly complex. Growing numbers of electronic control units are generating an unprecedented amount of network traffic. This is slowing performance, requiring frequent deployment of additional physical CAN-buses to support the extra traffic.

In addition, data heavy applications are demanding ever greater bandwidth, and cyber-security concerns are adding their own overhead.

CANpress is a solution designed to mitigate these challenges – extending the viability of modern and legacy CAN networks. To do this CANpress generates a stateless, lossless, and deterministic compressed CAN message frame, reducing network load.

Key featuresfeatures

  • Backward Compatibility

    No need to change gateways or non-participating ECUs as frame format remains unchanged
  • canpression

    Lossless

    No data is lost during the compression and decompression process
  • Low Latency

    Real-time processing means no significant latency added due to compression and decompression
  • Network Longevity

    Improved network efficiency extends CAN operative lifetime
  • Software Based

    No heavy resources required, allowing for the use of legacy and modern CAN architectures, reducing cost
  • Stateless

    Messages can be compressed and decompressed independently
