adsp2116x的矩阵乘运算

/**************************************************************

File Name:		matrix_test.asm

Date Modified:  2/22/00	GGL		
				6/6/00	GGL	modified so that SIMD is enabled in
							matrixbymatrix.asm instead of here
				6/7/00	GGL verified on 0.1 Si; doesn't work in 0.0

Description:	Program to call matrixbymatrix.asm
