Instruction Name Symbol Description Execution
Time (μSec)
Increment Whenever the input to this instruction is
ON, the data in the selected register is
incremented by 1. 1.6 μsec
Decrement Whenever the input to this instruction is
ON, the data in the selected register is
decremented by 1. 1.6 μsec
Log(10)
NA
Calculates Common Log (base 10) of
value in Operand A and puts result in
Operand C register. Ex. log
10
A=C
TBD
Log(e)
NA
Calculates the Natural Log value (base e)
in Operand A and puts the result in
Operand C register. Ex. log
e
A=C
TBD
Antilog(10)
NA
Calculates the common antilogarithm
(base 10) of value in Operand A and puts
the result in Operand C register.
Ex. if log
10
x=y, then antilog
10
y=x.
TBD
Antilog(e)
NA
Calculates the Natural antilogarithm
(base e) in Operand A and puts the result
in Operand C register.
Ex. if log
e
x=y, then antilog
e
y=x.
TBD
Compare Instructions
These are instructions which compare the values between two registers and, depending upon
the result (i.e. equal, greater than, less than, etc) turns ON the output.
Instruction Name Symbol Description Execution
Time (μSec)
Greater than If data in Operand A is greater than data
in Operand B, the output is turned ON. 2.2 μsec to 2.4
μsec
Greater than or equal If data in Operand A is greater than or
equal to the data in Operand B, the
output is turned ON. 2.2 μsec to 2.4
μsec
