摘要
传感器作为物联网应用的前端感知环点,在实际应用中常涉及浮点形式的模拟-数字(AD)转换计算,在此提供了一种可在16位单片机实现的"快速AD转换算法",在保证运算精度的情况下,通过定点数运算取代浮点数运算,极大地提高了时间和空间效率.
As a front-end perceptual annular point in the applications of Internet of things, sensor often combines with analog-digital conversion calculation in float form. This paper proposed a high speed AD conversion algorithm which can be implemented in 16-bit microcomputer. By using fixed-point operation instead of floating-point operation, time efficiency and space efficiency can be greatly improved without the loss of precision.
