编写TMS320C54x汇编语言程序，计算矩阵乘法：
要求：① 两个矩阵的数据由DATA段输入(可放在源程序中，也可单独建立一个数据文件)；
② 两个矩阵的数据从0口以数据文件IN.DAT输入，计算结果从1口以数据文件OUT.DAT输出。
,TMS320C54x assembly language program to prepare the calculation of matrix multiplication: Request: ① two matrices of data input from DATA paragraph (available on the source program, but also the establishment of a separate data file)　② two matrices of data from 0 to data IN.DAT document input, calculation results from the data file to an output OUT.DAT.
