为了检查一个字节中的某些位，可以让这个字节和屏蔽字(bit mask)进行按位与操作(C的按位与运算符为＆)——屏蔽字中与要检查的位对应的位全部为1，而其余的位(被屏蔽的位)全部为0。例如，为了检查变量flags的最低位，你可以让flags和最低位的屏蔽字进行按位与操作：flags&1；为了置位所需的位，...

After the declaration of the global pandemic, many AI experts have been tried to find how can be used Artificial Intelligence (AI) as a powerful tool in the fight against the COVID-19 pandemic. AI Technology, which includes Machine Learning (ML), Natural Language Processing (NLP), and Compu...
So, when you try to operate on bits, it's up to you or the compiler (depending on what language you're writing in) to write out additional operations that perform bit masking and strip the structure of everything but the information you actually want to operate on. If there are no ben...
Note well the bit masking. There are other ways that could be approached for mapping a single key, but for the case of multiple keys stored in contiguous bits of the same integer, you need to be careful to avoid contaminating the computed mappings with data from different keys. ...

The bitwise AND serves to mask out other set bits. Though if you are bit shifting the leftmost slot to the right, then the “incoming bits” are all zeroed anyway. But it’s probably a smart idea to make this masking a habit.
A method comprising identifying a portion of data in a first memory component to be written to a managed unit of a second memory component and determining whether an additional portion of data in the first memory component associated with the managed unit is stored at the cache memory. The ...
