从PC机的超级终端接受两个数和一个运算符，通过串口传给嵌入式系统，按操作符计算完两数后，把结果发还给PC机的超级终端，调试该程序，直到运行结果正确为止。（实现多位数的加减乘除）-From the PC-HyperTerminal to accept two numbers and an operator, passed through the serial port embedded systems, according to the calculation operator finished

Tiny6410裸机CPU初始化，DDR初始化，Nand启动，按键中断，串口中断-This is a program about tiny6410 without operator system.It has pll init,ddr init,nand init,key interrupt,uart interrupt and so on

实现任意位数的数字相加运算，或者叫大数运算，是任意位数的数字相加-Any median figure sum operator.

本程序在原来数组程序的基础上添加了模板、重载+、- 、=、==和！=运算符等操作。实现了对两个数组的加、减、赋值、判断是否相等等功能。-This procedure in the original array of procedures based on the added template, overloading+,- ,=,== And! = Operator and other operations. Achieved on the two array add, subtract, as
