Parallel Architecture
The typical expected performance for a parallel Viterbi IP core uses the Quartus II software with the Arria
V (5AGXFB3H4F40C4), Cyclone V (5CGXFC7D6F31C6), and Stratix V (5SGSMD4H2F35C2) devices.
The following parameters apply:
• v = 6 ×L
• N = 2
where:
• v is the traceback length
• L is the constraint length
• N is the number of coded bits
