This paper describes Emu, a new standard library for an FPGA hardware compiler that enables developers to rapidly create and deploy network functionality. Emu allows for high-performance designs without being bound to particular packet processing paradigms. Furthermore, it supports running the same programs on CPUs, in Mininet, and on FPGAs, providing a better development environment that includes advanced debugging capabilities. We demonstrate that network functions implemented using Emu have only negligible resource and performance overheads compared with natively-written hardware versions.
This paper describes a C# library that can be used to build networked programs which can compile to several target hardware and software platforms. This greatly eases development and debugging. The system is tested using NetFPGA as a target and performs almost as well as hand tuned code.
