RMModRM:reg (w)ModRM:r/m (r)N/AN/A Description¶ This instruction calculates the number of bits set to 1 in the second operand (source) and returns the count in the first operand (a destination register). Operation¶ Count = 0; For (i=0; i < OperandSize; i++) { IF (SRC...
Firstly, we create an arrayF[1<<21], F[i] : number 1 bits of i; // example:F[5] = 2 (5="101")F[7] = 3 (7="111") The main idea of this algorithm is separate that number into 3 blocks, each block have63/3 = 21bits; For example with a small number:X = "101101",...
Computes the bitwise population count (the number of bits set to 1) for each element of the input tensor, and writes the result into the output tensor. The bitwise operation is applied to tensor data in its native encoding. Therefore, the tensor data type is ignored except for de...
Iterate through each digit of the number. For each digit, create a bit representation. If the digit is d, then the bit representation is 1 << d. Use bitwise OR to updatemask. This marks the digit as seen. Count the number of bits set to 1 inmask. This count is the number of uni...
