Developing a proof-of-concept (PoC) for an emerging technology is important to learn what can and cannot be easily done, to reduce risk for future implementations, and lastly to convince skeptics that the technology is viable. This is true for the Open Domain-Specific Architecture (ODSA) effort where our PoC effort is trying to simultaneously address three dimensions of standardizing chiplet development. First, we need to address architectural issues like validating interface protocols, evaluating performance trade-offs, and developing software programming models. Second, we need to explore physical challenges like packaging issues, power distribution limitations, and high-speed I-O interfaces. Third, we need to expose the business issues that are unique to chiplets like how to share highly sensitive information on silicon design and business metrics that are exposed at the bare die-level. For the ODSA PoC workstream we have chosen to implement a module that can serve as a Smart Network Interface Card and also potentially as a Computation Storage Solution. This is an area where people are likely to create future domain-specific accelerators and represents a problem hard enough to expose real-world issues. It is also an area where members of the ODSA community have expertise and existing silicon components that can be leverage for creating a PoC. The physical implementation of the PoC involves a package design and a software development board created with discrete components. The PoC workstream focuses on a) architecture, b) physical implementation of package and board, c) bring up and testing. The board is architected in a modular manner such that the board design effort directly translates to the substrate design.
