Masking is the act of applying a mask to a value. This is accomplished by doing: Below is an example of extracting a subset of the bits in the value: Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits.
WebDec 13, 2024 · 1) Set the mask as right shift of integer by 31 (assuming integers are stored using 32 bits). mask = n>>31. 2) For negative numbers, above step sets mask as 1 1 1 1 1 1 1 1 and 0 0 0 0 0 0 0 0 for positive numbers. Add the mask to the given number. mask + n. 3) XOR of mask +n and mask gives the absolute value. (mask + n)^mask. WebA number that is used with the logical operators AND, OR or XOR to identify, remove or set a single bit or group of bits in an address or register. LSL - n. Bits in ACC are shifted logically n places to the left. Zeros are introduced on the right-hand end. LSR - n. Bits in …
WebI think my point still stands regarding C#. I doubt there are many 'tricks' you can use at the bit-level to speed up your code, because your compiler already knows those tricks and will use them for you. At the programming level you should concentrate on writing clear, concise code, and let the compiler worry about optimisation.
