ULL TCP/IP, UDP/IP Offload Engine

Overview

High-performance TCP and UDP IP offload engine cores offer a reliable, ultra-low-latency solution for financial and network applications. They address the data center industry’s growing need for throughput and hardware acceleration and provide network protocol offload for applications such as financial data processing, reprogrammable Smart NICs, and high-performance computing.

Three FPGA IP core versions are available through standard licensing options, including TCP/IP Offload Engine (ToE), UDP/IP Offload Engine, and a version supporting both TCP/IP and UDP/IP protocols offload.

Easily integrated with innovative technologies such as our ultra-low-latency Ethernet MAC PCS and PCIe DMA controllers, these cores radically change the way we think about speed and efficiency.

Key Features

Layer 2 through Layer 4 solution comprises:
- ARP, IPv4, and ICMP (ping)
- TCP and UDP

- Configurable number of connections, up to 64 per endpoint
- Server-side or client-side support, per connection
- TCP congestion control via fast retransmit/recovery
- TCP support for MSS, timestamps
- TCP Retransmission buffer
- Delayed Acknowledge
- RTO computation RFC-6298
- Checksum verification and calculation
Store/Forward, Cut-Through Mode
32b AXI-4 @ 322MHz (MAC side)
On-Chip application Interface :
