We propose high-radix CORDIC algorithm that calculate arc-sine and arc-cosine. CORDIC is used to calculating triangular function and so on, and can be implemented by simple hardware. Existing CORDIC algo- rithms for calculation arc-sine and arc-cosine is radix-2, so p times iterations is needed for p-bit accuracy. Proposed algorithm obtains same accuracy by fewer iteration because of high-radix. We assume input and output is double precision floating number and radix is 2^8, arc-sine can be calculated by 10 iterations. |
