[4x4] by [4x4] Matrix Multiplication (Modulo-Aligned)
;This routine performs a [4x4] by [4x4] matrix multiplication
;for the 96000 floating-point DSP chip.
;The data for all matrices is stored in row major
;format.
For example, take the matrix A:
;
;
;
;
;
;
;Matrix A's elements are stored as such:
B-128
; modulo N-squared addressing
