B.1.57 [16x16] by [16x16] Matrix Multiplication (Modulo Aligned)
;This routine performs a [16x16] by [16x16] matrix multiplication
;for the 96000 floating-point DSP chip. Sample data is given
;for N=16. The data for all matrices is stored in row major
;format. For example, take the matrix A:
;
; A(1,1) ... A(1,N)
; . . .
; . . .
; A(N,1) ... A(N,N)
;
;Matrix A’s elements are stored as such:
;amatrix dc A(1,1),A(1,2),...,A(1,N),A(2,1),A(2,2),...,A(2,N), ...
;
;Matrix A is in X memory, while matrices B and C are in Y memory.
;Since modulo N**2 addressing is used for all matrices, the first
;k least significant bits of the address of the beginning of any
;matrix storage area must be equal to zero, where 2**k >= N**2.
