E xample Code
T he following example is a code fragment that performs the
filter tap update for an adaptive (least-mean-squared algorithm)
filter. Notice that the computations in the instructions are
written like algebraic equations.
MF=MX 0*MY1 (RND), MX 0=DM (I2,M1);
MR=MX 0*MF (RND), AY0=PM (I6,MS);
DO adapt UNT IL CE;
AR=MR1 + AY0, MX 0=DM (I2,M1), AY0=PM (I6,M7);
adapt:
PM(I6,M6) =AR, MR=MX 0*MF (RND);
MODIFY (I2, M3);
MODIFY (I6, M7);
/* MF=error*beta */
/* Point to oldest data */
/* Point to start of data */
Interrupt E nable
T he ADSP-217x supports an interrupt enable instruction. Inter-
rupts are enabled by default at reset. T he instruction source
code is specified as follows:
Syntax:
ENA INT S;
Description:
Executing the ENA INT S instruction allows all
unmasked interrupts to be serviced again.
Interrupt Disable
T he ADSP-217x supports an interrupt disable instruction. T he
instruction source code is specified as follows:
Syntax:
DIS INT S;
Description:
Reset enables interrupt servicing. Executing the
DIS INT S instruction causes all interrupts to be
masked without changing the contents of the
IMASK register. Disabling interrupts does not
affect the autobuffer circuitry, which will operate
normally whether or not interrupts are enabled.
T he disable interrupt instruction masks all user
interrupts including the powerdown interrupt.
