Assembly 通过重复加法优化此乘法代码,以使循环次数最少
这个程序使用一个循环,通过使用 重复添加。我需要帮助优化程序,使其尽可能少地循环。例如 程序只会循环3次来计算3*6。即6+6+6Assembly 通过重复加法优化此乘法代码,以使循环次数最少,assembly,optimization,multiplication,marie,Assembly,Optimization,Multiplication,Marie,这个程序使用一个循环,通过使用 重复添加。我需要帮助优化程序,使其尽可能少地循环。例如 程序只会循环3次来计算3*6。即6+6+6 ORG 100 Load Y /load second value to be used as counter Store Ctr /Store as a counter Loop, Load Sum /load to the sum Add X /Add X to sum Store Sum /Store result in Sum Load Ctr Subt O

给定3*6示例,此乘法将循环6次或3次,具体取决于参数的顺序。因此,如果确保以较小的参数作为循环计数器,以较大的参数作为加数进入循环,则循环次数将减少 例如,检查一个是否较大,如果需要,在循环之前交换
