Corundum is an open-source FPGA-based network interface card (NIC) and platform for in-network compute, written in Verilog/SystemVerilog. It provides a high-performance 10G/25G/100G Ethernet datapath with PCIe DMA, thousands of hardware queues, PTP timestamping, TDMA scheduling, a Linux kernel driver, and an extensive simulation framework.

Use cases

• build a custom FPGA-based network interface card
• implement in-network compute offload on an FPGA
• run high-precision TDMA packet scheduling with PTP timestamping
• develop and simulate a full PCIe-to-Ethernet NIC design
• experiment with programmable network hardware on supported FPGA boards
• write a custom Linux network driver for FPGA hardware

When to choose

• you need an open-source, high-performance FPGA NIC with a mature Linux driver and simulation framework
• you want fine-grained control over transmit scheduling, queues, and PTP-based timing
• you are doing research on in-network compute or programmable networking
• your hardware is one of the many supported Xilinx or Intel FPGA boards

When to avoid

• you need a simple software-only networking solution without FPGA hardware
• your FPGA board is not among the supported devices and porting effort is too high
• you need a turnkey commercial NIC with vendor support rather than an open research platform
• you are not comfortable working with RTL (Verilog/SystemVerilog) and FPGA toolchains
