adaptive.asm

在TI的CCS环境下用C语言编写的lms算法,已经通过测试

;
;   adaptive.asm - Adaptive filter for system identification 
;                                  
;   Prototype: unsigned int adaptive(int *in, int *d, int *x, int *w,
;		   unsigned int Ns, unsigned int N, unsigned int index)
;
;   Entry: in[] - input signals
;          d[] - reference signal
;          x[] - adaptive filter delay-line buffer
;          w[] - adaptive filter coefficient array
;          Ns  - number of samples per block
;          N   - order of the adaptive filter
;          index - index to x[]
;
;   Return: T0 = Adaptive filter delay-line buffer index
