  2. 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

  3. 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.

  4. 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.
