One embodiment relates to a method for generating a periodic function in response to an argument in a digital signal processing system, where the periodic function can be represented as functions of two or more components of the argument. The method may include: obtaining a first operand from one of two or more lookup tables in response to a first component of the argument; obtaining a second operand from one of the lookup tables in response to a second component of the argument; conditionally mirroring the first and second operands in response to a quadrant of the argument; and calculating a value of the periodic function in response to the operands with a linear algebra unit without using conditional code execution.
