Description

This work proposes a synchronous version of Kyokko, a vendor-independent serial communication IP. Kyokko is our open-source implementation of Aurora 64B/66B and separates the device-independent protocol layer from the device-specific transceiver interface, enabling portability across multiple FPGA vendors. The original Kyokko design requires a 64:66 asynchronous gearbox on the FPGA's transceiver. However, as data rates increase, most recent FPGA transceivers omit asynchronous gearboxes, limiting the portability of the Kyokko. To address this, we redesign Kyokko for synchronous gearboxes that operate their PCS and PMA at the same clock frequency. The proposed architecture improves compatibility with recent transceivers from Altrera, AMD, Lattice, and other vendors. This work enables vendor-mixed FPGA-based instrumentation systems and computing environments.
