I want to check if any of the 1024 bits (128 bytes) are set. If all are clear, then I want to do something. Is it possible to do this quickly, i.e one instruction or do I have to loop through my bitma...

So currently (I don't know if the width is relevant) I have 2 128bit integers that I want to swap shift bits as shift is a part of a structure: unsigned char shift : 7; So I get the relevant bits lik...

I have a numpy array (dtype bool) representing an array of bits. For example, the array np.array([True, False, False], dtype=bool) represents the number 4 (indeed, bin(4) == 0b100). I would like to co...

I'm working on practicing my algorithms and getting into some bitwise stuff which I'm not too proficient with yet. So I have this function: def fn1(a): return (a >> 1) ^ a But I need to rev...
