overflow flag造句

例句与造句

1. The flags such as carry flag, overflow flag and zero flag.
2. For example, jz uses the zero flag, jc uses the carry flag and jo uses the overflow flag.
3. This is in contrast to the overflow flag which provides a mechanism for comparing the values as signed integer values.
4. The overflow flag would then be set so the program can be aware of the problem and mitigate this or signal an error.
5. The overflow flag is typically changed by all arithmetic operations, including compare instructions ( equivalent to a subtract instruction without storing the result ).
6. It's difficult to find overflow flag in a sentence. 用overflow flag造句挺难的
7. For both instructions, the Parity / Overflow flag ( bit 2 ) is set according to the current state of the IFF2 flip-flop.
8. The SO pin, on 6500 family CPUs that have it, sets the Overflow flag in the P register, which can be tested using BVC / BVS instructions.
9. Internally, the overflow flag is usually generated by an exclusive or of the internal carry " into " and " out of " the sign bit.
10. Along with a carry flag, a sign flag and an overflow flag, the zero flag is used to check the result of an arithmetic operation, including bitwise logical instructions.
11. Some processors support a hardware overflow flag that can generate an exception on the occurrence of an overflow, but it is usually too late to salvage the proper result at this point.
12. Therefore, it is useful to check the overflow flag after adding or subtracting numbers that are represented in two's complement form ( i . e . they are considered signed numbers ).
13. The overflow flag is thus set when the most significant bit ( here considered the sign bit ) is changed by adding two numbers with the same sign ( or subtracting two numbers with opposite signs ).
14. In many processor architectures, the overflow flag is cleared by bitwise operations ( and, or, xor, not ), possibly including shifts and rotates, but it may also be left undefined by these.
15. As the sign bit is the same as the most significant bit of a number " considered " unsigned, the overflow flag is " meaningless " and normally ignored when unsigned numbers are added or subtracted.
16. When the clock pulse occurs, the sum will be transferred to storage and, if the resulting sum is too large ( i . e ., it is larger than the ALU's output word size ), an arithmetic overflow flag will be set.
