Raw Blame History

OpenPiton FPGA SoC Platform

OpenPiton is the world's first open source, general purpose, multithreaded manycore processor. It is a tiled manycore framework scalable from one to 1/2 billion cores. Currently, OpenPiton supports the 64bit Ariane RISC-V processor from ETH Zurich. To this end, Ariane has been equipped with a different L1 cache subsystem that follows a write-through protocol and that has support for cache invalidations and atomics.

To build platform specific library and firmwares, provide the PLATFORM=fpga/openpiton parameter to the top level make command.

Platform Options

The OpenPiton platform does not have any platform-specific options.
