| Abstract: |
| This paper analyses the limitation of angle rotation range in CORDIC(Coordinate
Rotation Digital Computer) algorithm according to its principle, and proposes an
angle rotation structure covering 360 degree, and designs the pipeline circuit a
rchitecture of direction vector generator. The
mathematical deduction of CORDIC op
erator is given based on complementary form shifting and the circuit design of C
ORDIC iterat
ions. |
