The Draco Network Interface Chip

The Draco Network Interface Chip is a fifth-generation intelligent NIC processor. Featuring native PCIe interface and hardware-accelerated RDMA engines, it achieves end-to-end data transmission in 1μs latency while providing zero-overhead network stacks. Its innovative NoC interconnect architecture and onboard smart SoC management system improve network function offloading efficiency while reducing host CPU utilization to 1/5 of traditional solutions.
