SocketXpress — Hardware-Accelerated TCP/IP for Linux Applications

Stop Letting Software Bottleneck Your Edge Applications

On platforms like the AMD Kria KR260, the Linux software TCP/IP stack typically caps at ~3 Gbps under load — well below 10GbE's physical limit — because every packet burns precious CPU cycles your AI or control workload needs. SocketXpress intercepts standard POSIX socket calls via LD_PRELOAD and redirects them to a dedicated FPGA TCP Offload Engine, unlocking up to 9.4 Gbps with zero code changes to your application.

SocketXpress — HARDWARE TCP/IP ACCELERATION FOR LINUX

Why SocketXpress

🔌

LD_PRELOAD Drop-In

Intercepts POSIX socket calls at runtime — no recompilation, no source changes, no new APIs.

⚡

Near Line-Rate 10G

Achieves 9.4 Gbps TCP on AMD Kria KR260 — 3.6× faster receive than Linux software.

🧠

Full CPU Freedom

Entire TCP/IP stack runs in FPGA logic, keeping CPU free for inference and control.

📦

Flash-and-Boot Simple

Pre-configured SD card image boots with FPGA bitstream loaded automatically.

✅

Broad App Compatibility

Validated with iperf, curl, wget, ssh, scp, ftp, git, mysql, lynx, telnet — unmodified.
