OpenPiton is the world's first open source, general-purpose, multithreaded, manycore processor and framework. It is based on the Princeton Piton processor which was designed and taped-out in March 2015 by the Princeton Parallel Group. OpenPiton is open source across the entire computing stack, from the hardware to the firmware and software. Researchers and industry experts from many fields can utilize OpenPiton to modify any part of the stack and evaluate their ideas at scale. The hardware can be easily synthesized to FPGA and run an OS and applications at reasonable speeds for realistic evaluations. OpenPiton is designed to be highly configurable, including core count, cache sizes, and NoC topology, enabling it to adapt to different use cases. OpenPiton has an active community of users and is supported by the Princeton Parallel Group.
