Design of Smart Power-Saving Architecture for Network on Chip

Algorithm 3

Switch arbitration algorithm.

Switch arbitration

Input: body and tail flits

/*Control signal enable*/

(1)   while (body or tail flits) do

(2)   use channel sign up register to select local and global highest priority flits

(3)  if (local)

(4)   = local input virtual channel address}

(5)  if (global)

(6)   = global input virtual channel address}

(7)   end while

/*Channel switch*/

(8)   Case

(9)    = local packet of

(10) end case

(11)  Case

(12) = global packet of

(13)  end case
