单片机开发过程中必须用到的算法，如八位无符号数乘法，返回仍然是八位数；16位无符号数乘法；无符号8位数指数滤波函数，可用于AD或其他数据的滤波；无符号8位数二维查表算法等。简单实用-Algorithm the MCU development process must be used, such as the eight non-signed multiplication, the return is still the number eight　16 unsigned multiplication　Unsigned 8-bit index filter function, can be used for AD or other data filtering　unsigned 8-bit two-dimensional look-up table algorithm. Simple and practical! !
