The document discusses building a processor core using the open source POWER Instruction Set Architecture from the OpenPOWER Foundation. Specifically, it will summarize: 1) The OpenPOWER Foundation was created by IBM in 2013 to collaborate on Power ISA-based products which are open source, royalty free, and have no license fees unlike proprietary x86. 2) The project aims to build an FPGA-based processor core using the IBM A2I POWER processor design which was recently contributed to open source and can be used for AI/ML, HPC, and signal processing. 3) Successfully building this processor core could lead to developing a family of more powerful processors and even supercomputers using appropriate accelerators.

2. Why POWER ISA?
• The OpenPOWER Foundation is a collaboration around Power ISA-based products initiated by IBM and
announced as the "OpenPOWER Consortium" on August 6, 2013 [1].
• So Power ISA is Reduced Instruction Set Computer, Open source, royalty free, no license fee.
• If you have seen x86 is proprietary by Intel and due to this it is not freely available to student and
academicians to build processor core.
• For various embedded systems (chips), IBM came up with open sourcing this for everyone to develop their
own chips.

3. Abstract
• FPGA based Processor core using POWER Instruction Set Architecture (ISA) by OpenPOWER Foundation
by IBM.
• At The Linux Foundation Open Source Summit on 30th June 2020, the OpenPOWER Foundation announced a
major contribution to the open source ecosystem: the IBM A2I POWER processor core design and associated
FPGA environment.
• This processor core to be build can be targeted to work on AI/ML, HPC, Signal Processing.
• Looking at the power of the A2I processor core, we can go upto building supercomputers using appropriate
accelerators.

4. Future Development
• With success of this processor core we can support it with many open source cores and build our own
powerful chips.
• We can even have a family of processors with this basic processor core.
• This can lead to commercial production as well with appropriate necessary things.
