"UMI: Universal Memory Interface" - Andreas Olofsson (Latch_2024)

Andreas Olofsson https://fossi-foundation.org/latch-up/2024 Standardized bus architectures like Wishbone and AXI have helped designers construct complex systems from a basic set of interface compliant building blocks ("IPs"). The bus approach has worked well for decades, but requires a large number of wires to implement and does't scale particularly well. For PCB design and System-In-Package design, there are orders of magnitude less wires available and we need to take a fundamentally different approach to communication. The Universal Memory Interface (UMI) is a transaction based communication standard for accessing memory through request-response message exchange patterns, designd to work equally well for complex System-On-Chip designs and chiplet based System-In-Package design. UMI includes a complete open source reference implementation that has been used to design and manufacture four different chiplets in a 12nm CMOS process. The FOSSi Foundation is proud to announce Latch-Up, a conference dedicated to free and open source silicon. Latch-Up: a weekend of presentations and networking for the open source silicon community, much like its European sister conference ORConf.
