UOE6 — UDP Offload Engine for IPv6

UOE6 implements full hardware offload for UDP over IPv6, handling packet formation, parsing, validation, and forwarding entirely in RTL.

This eliminates CPU bottlenecks and provides a deterministic datapath for latency-sensitive, high-bandwidth systems.

• Converts UDP/IPv6 datagrams ↔ Ethernet frames at line rate
• Implements IPv6 Layer-3 functions including Echo, Neighbor Discovery (NDP), and MLD
• Offloads checksum construction/verification, header assembly, and protocol validation
• Ensures RFC-compliant behavior (UDP RFC 768, IPv6 RFC 8200)
• Integrates cleanly into AXI-Stream-based FPGA pipelines
• Tested and supported on both AMD and Intel/Altera devices

If your application needs deterministic UDP/IPv6 transport at high data rates, UOE6 provides a drop-in hardware solution.

• • Full IPv6 support including Echo, NDP, MLD
  • Line-rate UDP/IPv6 transmit and receive
  • RFC 768 & RFC 8200 compliant
  • Packet parsing and header synthesis in hardware
  • Configurable AXI-Stream interfaces
  • Deterministic latency and behavior
  • Cross-vendor FPGA support (AMD + Intel/Altera)
  • Lightweight integration, minimal resource footprint

Systems are rapidly transitioning to IPv6—especially in defense, data-center, sensor-fusion, and high-throughput embedded environments.

Software-handled IPv6 traffic often becomes a bottleneck due to larger headers, additional fields, extended addressing, and more complex L3 behaviors.

UOE6 removes all of that overhead:

• No CPU interrupts
• No OS packet stack traversal
• No firmware bottlenecks
• Predictable, low-jitter packet timing
• Guaranteed line-rate throughput

Your FPGA becomes a first-class IPv6 endpoint capable of sustained, deterministic packet flow.

• Sensor-to-compute streaming under IPv6
• Radar / EW / RF systems migrating from IPv4
• Data-center or cluster-connected FPGA accelerators
• High-rate UDP telemetry systems
• Real-time distributed embedded systems
• Any design requiring hardware-enforced IPv6 behavior

If your system already uses UOE, UOE6 provides a natural upgrade path:

• Similar integration pattern
• Similar control and configuration model
• AXI-Stream-friendly datapath
• Same emphasis on deterministic performance

Just with full IPv6 support added.
