CORDIC rotator and vectoring unit
Maturity fpga-routedTargets FPGA + ASICDifficulty MediumPriority 1
Iterative or pipelined CORDIC in rotation and vectoring modes (circular, linear, hyperbolic) for sin/cos, atan2, magnitude, phase and coordinate rotation.
FPGA-routed. The block meets timing on a routed FPGA netlist at a stated clock and its testbench passes on that netlist. It has not yet run on a board or in silicon.
