Math Instructions
These are instructions which can be used to initialize data or move data from one memory
location to another.
Instruction Name Symbol Description Execution
Time (μSec)
Addition Adds two signed registers and puts the
sum in a third register. 2.9 μsec to 3.2
μsec
Subtraction Subtracts the value in Operand B from
the value in Operand A and puts the
result in a third register, Operand C. 1.6 μsec to 3.5
μsec
Multiplication Multiplies the values in two registers and
puts the result in a third register. 2.0 μsec to 2.8
μsec
Division Word Divides the value in Operand A by the
value in Operand B and puts the result in
a third register, Operand C. Note: the
quotient is stored in C and the remainder
is stored in C+1. 8.8 μsec to 9.5
μsec
Division Unsigned
DWord/Word Divides the value in Operand A (32-bit
register) by the value in Operand B (16-
bit register) and puts the result in a 16-bit
register, Operand C. Note: the quotient is
stored in C and the remainder is stored in
C+1. 9.0 μsec
Addition with Carry Adds two registers, along with the carry
bit (S0) and puts the sum in a third
register. If the carry bit was set during
this operation, the carry flag is turned
ON. Use this instruction when adding
two unsigned numbers or 32-bit
registers. 3.5 μsec
Subtraction with
Carry Subtracts the value in Operand B, along
with the carry bit (S0) from the value in
Operand A and puts the result in
Operand C register. If the carry bit was
set during this operation, the carry flag is
turned ON. Use this instruction when
subtracting two unsigned numbers or 32-
bit registers. 3.5 μsec
