dsp中的键盘控制程序的算法，基于TI公司的5509这款dsp芯片。

1、（1）32bit乘法的指令解释 （2）volume1的load.asm基础上实现一个 16bit数组的乘法累加的函数，并进行 -o2 / -o3 / 手工优化 2、c环境 C调用汇编函数，汇编函数调用c函数 addarr3(int * arr1, int * arr2, int * arr3, int * arr4, n) //汇编函数，3个数组的对应位置相加，结果放在arr4[n]中， 汇编函数调用C的子函数，它把arr1和arr2相加放到arr3[n]中； addarr2(int * arr1, int * arr2, int * arr3, n)-1, (1) 32bit multiplication instructions explained (2) the load.asm volume1 on the basis of a a 16bit multiplication cumulative array of functions, and-o2 /-o3/2 manual optimization, c environment compilation called C function, the compilation function call c function addarr3 (int* arr1. int* arr2, arr3 int*, int* arr4, n)// compilation function, 3 arrays corresponding location together, the results on arr4 [n], the compilation of the C function call function, arr1 put it together and put arr2 arr3 [n]; addarr2 (int* arr1, int* arr2, int* arr3, n)
