计算一个整数的二进制表示中1的个数,该算法循环的次数只与整数的二进制表示中1的个数有关。相比与循环遍历所有位的方法，该算法在一般情况下能够大幅减少循环的次数，提升效率。 比如我们可以用一个整数做标识位，64位整数最多可以对应64个状态，可以用这个函数获取当前有效状态的个数-Calculate an integer number of the binary representation of the number of 1' s, this algorithm the numbe

AD after eight bits data were treated with fpga, and get the measuring frequency and amplitude of the analog signal information, and put this information in the digital tube display.

HPL is a software package that solves a (random) dense linear system in double precision (64 bits) arithmetic on distributed-memory computers. It can thus be regarded as a portable as well as freely available implementation of the High Performance Co
