This mode is used when the full frame does not fit into the coprocessor traceback memory and the frame is terminated. The frame is split into sliding windows. The state metrics are computed over F + K - 1 symbols, the traceback is initialized with the tails state and executed over F + K - 1 symbols. It should be noted that only F decisions are output in blocks of user-defined size (see Section Figure 30-7). The state metrics computation of sliding window i + 1 is done in parallel with the traceback computation of sliding window i. Tailed traceback type is used on the last sliding window.
Figure 30-8 shows the sliding windows diagram for Mixed Traceback Mode.
