Thanks for the answers. You can give an answer. What accuracy can cordic provide if, for example, we have a 16-bit sine output, and 16 iterations? In theory, when arctangent coefficients are given, 16 arctanges (the last one) is arctg( 2^(-15) )= 0.001°. Does this mean we will have the maximum error of the 16-bit output sin(0.001°)*2^16?
