如何衡量LC3汇编程序的性能？

如何解决如何衡量LC3汇编程序的性能？

例如，有许多用于右移的 LC3 汇编程序，根据程序运行的速度来评估它们是否有意义？有没有办法在python等脚本语言中嵌入汇编程序来测量它的速度？

解决方法

It can be measured indirectly via running a script:
1: create a script for lc3sim denoted as: lc3_run.txt
    #cat lc3_run.txt
        file test.obj
        c
    #

2. create a shell script denoted as: perf_test.sh
    #cat perf_test.sh
        set -x
        n=0
        while [ $n -lt 1000 ]
        do
            lc3sim  -s lc3_run.txt
            ((n+=1))
            echo $n
        done
     #chmod +x perf_test.sh
     #time ./perf_test.sh
        real    0m14.512s
        user    0m3.552s
        sys 0m3.304s

    #3. compare the run time to evaluate which one is faster under 
        same conditions (HW/SW)
