摘要： The present disclosure provides a method for instruction processing. The method may include adding a first operand from a first register, a second operand from a second register and a carry input bit to generate a sum and a carry out bit. The method may further include loading the sum into a third register and loading the carry out bit into a most significant bit position of the third register to generate a third operand. The method may also include performing a single bit shift on the third operand via a shifter unit to produce a shifted operand and loading the shifted operand into the fourth register. The method may further include loading a least significant bit from the sum into the most significant bit position of the fourth register to generate a fourth operand. The method may additionally include generating a greatest common divisor (GCD) of the first and second operands via the fourth operand and generating a public key based on, at least in part, the GCD. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
