OpenPiton is the worlds first open source, general-purpose, multithreaded, manycore processor and framework. It is based on the Princeton Piton processor which was designed from December 2013 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. Some of the features of OpenPiton include:
You can download RTL resources and corresponding infrastructure for free. Your download also includes OpenPiton documentation.
You can also clone OpenPiton on GitHub
You can discuss your possible issues in this discussion group. Our team members keep an eye out for helping you.
Princeton Parallel Group mainly focuses on the design of future computing architectures and software systems for data centers and cloud computers. The group also investigates the broad area of green computing including how to minimize the impact of computing systems on the environment and how to design computer systems to be serviced and ultimately decommissioned in a sustainable manner.
