The Open Domain-Specific Architecture is a sub project of the Server project established at the 2019 Global Summit. The ODSA aims to establish both an open ecosystem and an open marketplace of chiplets to support the design of domain-specific accelerators and other devices. In one year, the ODSA has grown to a project with seven active work streams and with active participation from more than 25 companies. To enable the ecosystem and marketplace, the ODSA aims to create an open inter-chiplet interface, provide proof-of-concept demonstration vehicles and establish workflows to use chiplets for product development. This talk will review the progress made by the ODSA, significant milestones, their impact on product development and how new participants can contribute.
