Processing details
• These instructions search for the maximum value in the (n) point(s) of single-precision real number block data in the device
starting from the one specified by (s), and store the maximum value in the device areas specified by (d). These instructions
also store the location of the first maximum value from (s) in the device specified by (d)+2 and the number of maximum
values in the device specified by (d)+3.
• The start of the block data in the device specified by (s) is counted as 1st point when the location is counted.
(s)+1, (s)
(s)+3, (s)+2
(s)+5, (s)+4
(s)+7, (s)+6
(s)+9, (s)+8
(d)+1, (d): Maximum value
(d)+2: Position
(d)+3: Number of data
• The following values are stored in (d).
(d)
(d)+1
(d)+2
(d)+3
• When (n) is 0, the processing is not performed.
