方法CountSetBits會傳回在指定位欄位中設定為 1 的位數。 語法 C++複製 DWORDCountSetBits(constDWORD Field ); 參數 欄位 將位欄位指定為DWORD值。 傳回值 傳回設定為 1 的位數。 規格需求 需求值 標頭 Winutil.h (包含 Streams.h) 程式庫
我很好奇,由BitTwiddling Hacks指出,与简单的Lookup Table方法相比,该算法的性能要好得多...现在,我想,也许我的一点研究对其他人也很有趣... PS:并行计数算法大约是35在我的计算机上平均比simpel LUT解决方案快%。 这也很好地显示了与人脑兼容的解决方案与二进制机器
Counts the number of set bits in _X inline unsigned int countbits( unsigned int _X ) restrict(amp); Parameters _X Unsigned integer value Return Value Returns the number of set bits in _X Requirements Header:amp.h Namespace:Concurrency::direct3d ...
The result of this operation will turn off all the bits and keep the last set bit on. After that, we delete that last set bit from and increase our answer by one.When the number becomes equal to zero, the answer will have the number of set bits in the given integer ....

If the decoder does not provide the error count automatically, then the destination receiver can always encode the information bits from a correctly decoded packet and compare them with the binary representations of the demodulator hard decisions for the packet, as illustrated in Figure 21.1. ...
