Abstract
A communications reduced instruction processor forming a simple programmable digital signal processing architecture (10) for processing analog waveforms. The architecture (10) includes a main DSP core that includes a tightly coupled CORDIC co-processing element (26). The CORDIC co-processing element (26) performs trigonometric operations for converting polar coordinates to rectangular coordinates and rectangular coordinates to polar coordinates. These trigonometric functions include an angle accumulate operation for calculating the magnitude and angle of a vector given in X-Y cartesian coordinates, and a vector rotate operation for calculating a sine and a cosine of a given phase angle.
