Abstract:
A method and system for rotating a vector, including at least one lookup table (LUT) including data corresponding to the vector being rotated around a first angle and a second angle, processing circuitry configured for accessing the at least one LUT for incrementally rotating the vector around the first and second angles, where accessing includes identifying an LUT input entry and selecting a corresponding LUT output entry, the corresponding output entry including an incremental angular rotation (IAR) of the vector around the first angle or the second angle, and a comparator configured to generate a comparator signal based upon comparing a counter incremented by the IAR with the first angle or the second angle, the processing circuitry further configured to iteratively access the at least one LUT, based on the comparator signal, for completing the incremental rotation of the vector around the first angle and the second angle.
