Processing details
■Operation processing
• Performs comparison operation between the values input to variables (s1) to (s28), and outputs the operation result from
(d) in bit type as that of variables (s1) to (s28).
GT_E
Performs comparison of [(s1)>(s2)]&[(s2)>(s3)]&  & [(s)
• Outputs TRUE if all of comparisons satisfy (s)
• Outputs FALSE if any of comparisons satisfies (s)
GE_E
Performs comparison of [(s1)  (s2)]&[(s2)  (s3)]&&[(s)
• Outputs TRUE if all of comparisons satisfy (s)
• Outputs FALSE if any of comparisons satisfies (s)
EQ_E
Performs comparison of [(s1) = (s2)]&[(s2) = (s3)]&&[(s)
• Outputs TRUE if all of comparisons satisfy (s)
• Outputs FALSE if any of comparisons satisfies (s)
LE_E
Performs comparison of [(s1)  (s2)]&[(s2)  (s3)]&&[(s)
• Outputs TRUE if all comparisons satisfy (s)
• Outputs FALSE if any of comparisons satisfies (s)
LT_E
Performs comparison of [(s1) < (s2)]&[(s2) < (s3)]&&[(s)
• Outputs TRUE if all comparisons satisfy (s)
• Outputs FALSE if any of comparisons satisfies (s)
NE_E
Performs comparison of [(s1)  (s2)].
• Outputs TRUE if (s1)  (s2).
• Outputs FALSE if (s1) = (s2).
