According to the statistical results, the threshold is set to 300. When a certain TAGE table is not used continuously for more than the threshold, the table will be closed. When a redirection occurs, the closed tables will be reopened.

6289933 
    Add a counter to each table to record the number of
    consecutive misses or hits that do not participate in prediction.
    When the counter value reaches the threshold,
    close the read request for the table.
    When a redirect is detected, reopen the closed table.
