Tutor description

This is implemented for a range of input values < 0.75 since Xin should be less than 1 for the bit notation we used.Here we use the vectoring Mode of CORIC and its Hyperbolic subcase to calculate Xout=sqrt(xin2 -yin2 ) And yout= 0 Bit notation: [MSB(sign bit)] . [(bit 1 to 15 for +ve fraction)] If we use xin=M+ ¼ and yin=M -1/4 we can compute xout=sqrt(M)

[(bit 1 to 15 for +ve fraction)]If we use xin=M+ and yin=M -1/4 we can compute xout=sqrt(M). The other equations of the cordic remain the same ie, X(i+1)=x(i)+d(i)*y(i)*2-i Y(i+1)=y(i)+d(i)*x(i)*2-i Z(i+1)= z(i) - d(i)*a(i) where a(i)=tan-1 (2-i) In this case we use 16bit fixed point notation with one sign bit and 15 bits in Q15 notation.
