摘　　要：在单片机应用中常碰到比较多字节数值、确定最小数值所在组的问题。利用最高位数值存储单元地址作为组别标志,提出了筛选多字节数值最小组别的汇编语言算法,计算结束后将最小组别标志存储于固定单元中。在该算法的基础上,通过设置后一级数值比较的起始地址及循环控制起始数值,可完成无限字节数值最小组别筛选,也可修改关键程序完成最大组别筛选。In the application of MCU, we often encounter the problem of comparing multibyte values and determining the group of the minimum value. By using the address of the highest bit value storage unit as the grouping symbol, an assembly language algorithm is proposed to filter the multibyte value and store the minimum grouping symbol in a fixed unit after the calculation. On the basis of this algorithm, by setting the starting address of the value comparison in the later level and circularly controlling the starting value, the minimum group filtering of infinite byte value can be completed, and the maximum group filtering can also be completed by modifying the key program.
