Abstract
A method for approximating an upper bound limit for the absolute value of a complex number or the norm of a two-element vector is disclosed. An upper bound approximation algorithm is used to minimize software implementation efforts and make the hardware implementation less expensive. The hardware implementation of the upper bound approximation algorithm only requires a multiplier element and an adder element. Therefore, this algorithm can be implemented anywhere in a digital signal processing apparatus without increasing cost significantly. Moreover, the hardware employing the present invention can be implemented in a pipeline architecture configuration to achieve a real time function in digital audio or digital video applications.
