Abstract:
1. A system for accurately calculating a mathematical power function for performing one or more signal-processing tasks in an electronic device, comprising: an application program configured to calculate a direct estimate of power function value for said mathematical power function during a direct linear interpolation procedure, said application program also calculating an indirect estimate of power function value for a complement power function during an indirect linear interpolation procedure, said application program then performing a final function-estimate calculation procedure to produce a final estimated power function value from said direct estimate of power function value and said indirect estimate of power function value; and a processor device configured to control said application program for accurately calculating said mathematical power function, said mathematical power function being utilized to perform signal processing applications in at least one of an MPEG Advanced Audio Coding environment and an MPEG I/II, layer 3 environment.
