BOR (Bitwise OR) is one of the opcodes in the DCPU-16 specification. It represents a bitwise OR operation.
Contents |
Usage
BOR arg1, arg2
BOR performs a bitwise OR on arg1 with arg2 and stores the result in arg1. That is, the bits equal to 1 in either arg1 or arg2 become 1 in the result; all other bits are set to 0.
| Input A | Input B | Output Y |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
Example
SET A, 5 ; 0b0101 BOR A, 3 ; 0b0011 ; A is now 0b0111
Signing dependence
BOR works correctly with both signed and unsigned numbers.
Processing
In binary machine code, this Basic opcode's five-bit representation is: 0b0 1011 (0x0b)
The instruction has a takes one cycle to execute, plus any additional cycles necessary to evaluate the arguments.
