Open Compute Project

Chiplet-based designs can potentially enable the cost-efficient development of domain-specific architectures. The interest in die-to-die (D2D) interconnect has grown with the increase in interest in chiplet-based design. Correspondingly, interest has grown in open technologies for die-to-die communication. The Open Domain-Specific Architecture is a new project from the Open Compute Project that aims to establish open physical and logical interfaces for chiplets. The interfaces aim to leverage existing protocols where possible. With these open interfaces, the ODSA aims to create a marketplace of interoperable chiplets from multiple vendors. Participants can either provide IP to this marketplace or sell IP as chiplets. This will allow product designers to integrate best in class chiplets from multiple vendors. This talk will review technical developments by the ODSA including open PHY technologies, the ODSA protocol stack and a proof-of-concept (PoC) prototyping activity that aims to integrate chips from multiple vendors into one package. We will also review software approaches to using accelerators in applications on the host. This discussion will review potential applications for the PoC, and by extension chiplets, for storage applications.
