WebIn computer science, a maskor bitmaskis data that is used for bitwise operations, particularly in a bit field. Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation. WebTheoretically, if we never have more than 256 variants, our variants never have more than 3 Register values (or one Register and one LiteralInteger sized value), the compiler should be able to pack Opcode into 32 bits.

Web26 de jul. de 2016 · Each instruction has an opcode and an address part. All instructions are stored in memory. As there are 150 instructions. So there will be, 8 bits for representing one operation as, Thus, 8 bits are needed for opcode. An instruction is stored in a word with 24 bits. So, there will be (24-8) = 16 bits for an address part in an instruction. Web" Similarly, note that ORing a bit with 1 produces a 1 at the output while ORing a bit with 0 produces the original bit. " This can be used to force certain bits of a string to 1s. " For example, 0x 12345678 OR 0x0000FFF results in 0x1234FFFF (e.g. the high-order 16 bits are untouched, while the low-order 16 bits are forced to 1s). 26
