Breaking the Data Movement Bottleneck Chiplets Summit Session

Kent Orthner, Principal Solutions Architect at Baya Systems, talks about multi-die coherent networks and how this software fabric approach works with chiplets (watch the video above). Essentially, chiplets require one or more network-on-chip (NoC) subsystems to tie together the functional blocks. These can be a mix of coherent and non-coherent NoCs. The Baya Systems design flow allows designers to design these systems (see figure).

Baya Systems’ tools address on-die as well as cross-die and cross-chip communication. This includes support for multi-chiplet coherency, global address maps, and deadlock avoidance across dies and chips. The tools can be used for traffic simulation.
