2) Operation example
a) Example of search result table configuration and data
b) Search result table
2. 32-bit operation (DSER and DSERP)
In "n" data starting from [ +1, ], same data as [ +1, ] is searched, and the search result is
stored to [ +1, ] to [ +9, +8].
1) Contents of searched data and the search result
a) When same data was detected
Five 32-bit devices starting from [ +1, ] store the number of same data, first position, last position,
maximum value position and minimum value position.
b) When same data was not detected
Five 32-bit devices starting from [ +1, ] store the number of same data, first position, last position,
maximum value position and minimum value position.
In this case, however, "0" is stored in three devices starting from [ +1, ] (which store the number of
same data, first position and last position).
