Table 5-2. Summary of Supported Trailing Searches
MultiSearch operations use different CPR registers (different Mini-Key, Soft Priority, and width configuration values) for the two
searches. Depending on the location of the leading search in the data array (Array 0 or Array 1), the GMR/CPR selection will vary.
Leading search in Array 0: By indicating the GMR used for the leading search width in the MultiSearch, the corresponding CPR
is automatically selected (GMR0 selects CPR0). The trailing search (must be smaller or equal width) is automatically assigned
the configuration specified in the CPR immediately following the one specified for the leading search. Therefore, if the leading
search specifies CPR3, the trailing search will use CPR4. With respect to the GMR, the GMR registers specified for the leading
search will automatically select the subsequent GMR registers for the trailing search. This is best shown in Table 5-3.
Table 5-3. GMR and CPR Selection When Leading Search is in Array 0
Leading search is located in Array 1: The GMR/CPR selection process changes slightly. Specifically, the GMR usage specified
on the CMD bus at the time of the search is used for the trailing search, and not the leading search. Otherwise, the reverse of
Table 5-3 is true. The new GMR/CPR selection matrix is presented in Table 5-4.
