Then use this table to find the number of ones in each byte of the integer and sum them to get total number of set bits in an integer. Here, we take the size of integer by sizeof operator and iterates the loop maximum for sizeof(int) times. While counting the set bits we iterate...
Count bits set in parallel(查找32位整形数中置1的个数) 如果要计算一个整形中的位数有多少位被置位,我们的第一想法就是循环查找。现在我们可以参考:http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel unsignedintbits_counter_v4(unsignedintx) {//count bits of each 2-bit chunkx...

Set Tick interval of the X-axis and Unit of the Y-axis on the IO Graph page. For a GE port, set Tick interval of the X-axis to 0.001 sec (millisecond) and Unit of the Y-axis to Bits/Tick. Then the calculated packet rate will be expressed in kbit/s. Figure 9...
