数字I/O实验主要完成的功能： 在此实验中，SEED-DEC5416 首选进行初始化，包括对外设 UART、本身频率的设定及一些状态区的初始化。然后等待 SEED-MMI5402 发送命令；SEED－DEC5416 响应交通灯自动模式、交通灯手动手动模式、交通灯东西通、交通灯南北通、及交通灯的禁行与夜间模式的操作命令。同时还响应，对 SEED-DEC5416 的复位及两个单元之间的通讯故障。 -Digital I/O completion of the experiment the main features: In this experiment, SEED-DEC5416 preferred to initialize, including peripherals UART, their frequency settings and some of the initialization state of the district. SEED-MMI5402 and then wait to send commands SEED-DEC5416 automatic mode in response to traffic lights, traffic lights manual manual mode, the traffic light east-west pass, pass traffic lights north and south, and traffic lights at night and cut-line mode command. At the same time, also responded to the SEED-DEC5416 reset and communication between two modules fault.

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)
