The S4NoC Network-on-Chip

  • Message passing
  • All-to-all communication
  • TDM scheduling - no handshaking
    • Time-predictable
    • When receiver cannot catch up, messages are dropped
  • Simple memory mapped interface
    • status register (TX empty, RX full)
    • data register (TX data, RX data)
    • destination/source register (TX destination, RX source)
  • See README of example for an example

Description


The S4NoC is a message passing network-on-chip (NoC) with an all-to-all
communication pattern. S4NoC uses TDM scheduling to be time-predictable.


The network interface and the S4NOC are written in Chisel and the
source can be found in s4noc


The tests can run from the current folder with a plain


sbt test
