Introduction

============

Corundum is an open-source, high-performance :term:`FPGA`-based :term:`NIC` and platform for in-network compute. Features include a high performance datapath, 10G/25G/100G Ethernet, PCI express gen 3, a custom, high performance, tightly-integrated :term:`PCIe` :term:`DMA` engine, many (1000+) transmit, receive, completion, and event queues, scatter/gather DMA, :term:`MSI`, multiple interfaces, multiple ports per interface, per-port transmit scheduling including high precision TDMA, flow hashing, :term:`RSS`, checksum offloading, and native IEEE 1588 :term:`PTP` timestamping. A Linux driver is included that integrates with the Linux networking stack. Development and debugging is facilitated by an extensive simulation framework that covers the entire system from a simulation model of the driver and PCI express interface on one side to the Ethernet interfaces on the other side.

|
Corundum has several unique architectural features. First, transmit, receive, completion, and event queue states are stored efficiently in block RAM or ultra RAM, enabling support for thousands of individually-controllable queues. These queues are associated with interfaces, and each interface can have multiple ports, each with its own independent scheduler. This enables extremely fine-grained control over packet transmission. Coupled with PTP time synchronization, this enables high precision TDMA.
|
|
|
|
Corundum also provides an application section for implementing custom logic. The application section has a dedicated PCIe BAR for control and a number of interfaces that provide access to the core datapath and DMA infrastructure.
