Good question! CORDIC and HAKMEM Item 149 are both hardware-friendly, but have different trade-offs:

CORDIC: - Iterative algorithm (needs multiple clock cycles) - Accuracy improves with more iterations - Generates both magnitude and phase - Typical hardware implementation: 12-16 iterations for decent precision

HAKMEM (Item 149): - Single-cycle computation (just two adds per step) - Uses the recurrence: x' = x - εy, y' = y + εx - Accuracy depends on word width and epsilon choice - Numerically stable in exact arithmetic if ε² < 2
