Region based routing a mechanism to support ef cient routing algorithms in nocs

  • Perceived higher cost , higher power consumption, and lack of scalability when implementing the tables in SRAM memories.

  • As the system increases in size, the memory requirements for building such routing tables also increase

  • FSM-based switch (FSM)

    • implements the Dimension Order Routing (DOR) routing algorithm.

  • Table-based switch (TB)

    • A table of N * 2 * d bits for the table-based implementation.

  • Region-based switch (RB)

    • 16 regions were used for the region-based switch

      Mapped on a 90-nm technology library from TSMC.

  • In terms of area and power dissipation consumption, a region-based switch is less than 4% more expensive than an FSM-based switch and more than 55% cheaper than a table-based switch

  • In terms of power consumption, a region-based switch is less than 1% more expensive than an FSM-based switch and more than 45% cheaper than a table-based switch.
