示例
#define BUFFER_SIZE_T 9
void AddExample(void)
{
uint32_t src1[BUFFER_SIZE_T] = {1598181665, 1446829146, 2752624014, 2171200733, 2676378769, 1078554841, 1318511000, 2592925506, 2518880388};
uint32_t src2[BUFFER_SIZE_T] = {422526272, 1563791282, 1664517688, 1278844750, 1984585164, 1554125489, 1115993496, 1182866132, 2965039412};
uint32_t dst[BUFFER_SIZE_T] = {0};
HmppResult result = HMPPS_Add_32u(src1, src2, dst, BUFFER_SIZE_T);
printf("result = %d\n", result);
if (result != HMPP_STS_NO_ERR) {

}
printf("\ndst = ");
for (int32_t i = 0; i < BUFFER_SIZE_T; i++) {

}
运行结果：
result = 0 dst = 2020707937 -1284346868 -1 -844921813 -1 -1662286966 -1860462800 -519175658 -1
