3.3 Application Instruction
Description
[(s1)+1, (s1)] = [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Non-Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)] = [(s2)+1, (s2)]: Non-Conductive
[(s1)+1, (s1)] > [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Non-Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)] > [(s2)+1, (s2)]: Non-Conductive
[(s1)+1, (s1)] < [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Non-Conductive
[(s1)+1, (s1)]  [(s2)+1, (s2)]: Conductive
[(s1)+1, (s1)] < [(s2)+1, (s2)]: Non-Conductive
This instruction compares two data values (single-precision real numbers), and outputs the result
(larger, smaller or equal) to three bit devices.
This instruction compares two data values (single-precision real numbers), and outputs the result
(larger, smaller or data band) to three bit devices.
Description
• In case of 2 operands
[(d)+1, (d)] + [(s)+1, (s)]  [(d)+1, (d)]
• In case of 3 operands
[(s1)+1, (s1)] + [(s2)+1, (s2)]  [(d)+1, (d)]
• In case of 2 operands
[(d)+1, (d)] - [(s)+1, (s)]  [(d)+1, (d)]
• In case of 3 operands
[(s1)+1, (s1)] - [(s2)+1, (s2)]  [(d)+1, (d)]
Description
[(s1)+1, (s1)]  [(s2)+1, (s2)]  [(d)+1, (d)]
[(s1)+1, (s1)]  [(s2)+1, (s2)]  quotient [(d)+1, (d)]
Description
Converts the 16-bit signed binary data in the device specified by (s) to single-precision real
number, and stores the converted data in the device specified by (d).
Converts the 32-bit signed binary data in the device specified by (s) to single-precision real
number, and stores the converted data in the device specified by (d).
