3. 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

12. 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.

13. 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.
