Assembly Code E xample
T he following example is a code fragment that performs the filter tap update for an adaptive filter based on a least-mean-squared
algorithm. Notice that the computations in the instructions are written like algebraic equations.
MF=MX0*MY1(RND), MX0=DM(I2,M1);
MR=MX0*MF(RND), AY0=PM(I6,M5);
DO adapt UNTIL CE;
AR=MR1+AY0, MX0=DM(I2,M1), AY0=PM(I6,M7);
PM(I6,M6)=AR, MR=MX0*MF(RND);
{MF=error*b eta}
adapt:
MODIFY(I2,M3);
MODIFY(I6,M7);
{Point to oldest data}
{Point to start of data}
