Data processing

Data processing instructions
■Adding 16-bit binary data
Instruction symbol Processing details
WSUM Adds the (n) points of 16-bit binary data in the device starting from the one specified by (s), and
stores the result in the device specified by (d).
WSUM_U
■Adding 32-bit binary data
Instruction symbol Processing details
DWSUM Adds the (n) points of 32-bit binary data in the device starting from the one specified by (s), and
stores the result in the device specified by (d).
DWSUM_U
■Calculating the mean value of 16-bit/32-bit binary data
Instruction symbol Processing details
MEAN Calculates the average value of the (n) points of 16-bit data in the device starting from the one
specified by (s), and stores the average value in the device specified by (d).
MEAN_U
DMEAN Calculates the average value of the (n) points of 32-bit data in the device starting from the one
specified by (s), and stores the average value in the device specified by (d).
DMEAN_U
■Calculating the square root of 32-bit binary data
Instruction symbol Processing details
DSQRT Performs a square root operation of the specified 32-bit binary data.
√(s)+1, (s)→(d)
*1 When calculating the square root except 32-bit binary data, use SQRT of standard functions.
