We propose an algorithm based on Least Common Multiple (LCM) to minimize the number of PLLs required to generate the clocks for the IP cores in a SoC. This is done by finding an Optimum Operating Frequency (OOF) for each IP core within 10% below the maximum operating frequency of the ...

解题思路:求两个数的最小公倍数=两个数相乘,再处理最大公约数。最大公约数用辗转相除术。 最大公约数和最小公倍数说明见下面连接: https://jingyan.baidu.com/article/0964eca21e03ac8285f53602.html #include <iostream> #include <algorithm> ...

相除法, 又名欧几里德算法(Euclidean algorithm),是求最大公约数的一种方法。它的具体做法是:用较除较大数,再用出现的余数(第一余数)去除除数,再用出现的余数(第二余数)去除第一余数,如此反复,直到最后余数是0为止。如果是求两个数的最.. C语言 用更相减损术...
The bolded numbers are those that we changed from the previous step. Thus we find that LCM(2,3,5) = 30. The algorithm is guaranteed to converge to a solution, if there is one. As you can see, it can take quite a lot of steps even for small numbers like these making automation of...
