This mode is used with nonterminated frames or when must decode a portion of the frame. When the frame does not fit into the coprocessor traceback memory, then the frame is split into sliding windows. The state metrics are computed over F + C symbols, the traceback is initialized with the tails state and executed over F + C symbols. It should be noted that only F decisions are output in blocks of user-defined size (see Section Figure 32-7). The state metrics computation of sliding window i + 1 is done in parallel with the traceback computation of sliding window i.
Figure 32-9 shows the sliding windows diagram for Convergent Traceback Mode.
