If the addition operation produces a result too large for the CPU to handle, an arithmetic overflow flag in a flags register may also be set.

If the compiled program can run on a computer whose CPU or operating system is different from the one on which the compiler runs, the compiler is known as a cross-compiler.

If the hardware provides multiple rings or CPU modes, the microkernel is the only software executing at the most privileged level ( generally referred to as supervisor or kernel mode ).

If there is sufficient commercial interest, a hardware implementation of the CPU specification may be built ( e. g., the Pascal MicroEngine or a version of the Java processor ).

If no other hardware responds, the CPU raises an exception, stating that the requested physical address is unrecognized by the whole computer system.

If the CPU guesses wrong, all of these instructions and their context need to be " flushed " and the correct ones loaded, which is time-consuming.

If, for instance, every instruction run in the CPU requires an access to memory, the computer gains nothing for increased CPU speed — a problem referred to as being " memory bound ".

If PC is a binary counter, it may increment when a pulse is applied to its COUNT UP input, or the CPU may compute some other value and load it into PC by a pulse to its LOAD input.

If the receiving process is waiting for the message, control of the CPU is transferred at the same time, without a pass through the CPU scheduler.

If the CPU does not service the UART quickly enough and the buffer becomes full, an Overrun Error will occur, and incoming characters will be lost.

If the CPU heatsink or fan is changed on such boards, other heatsinks may not be cooled sufficiently.

If this too fails, the CPU traps into the OS ( with MMU disabled ) so that the problem may be resolved.

If a CPU or controller or bus failed, the disk was still reachable through alternative CPU, controller, and / or bus.

If a process has recently run on one virtual hyper-threaded CPU in a given core, and that virtual CPU is currently busy but its partner is not, cache affinity would suggest that the process should be dispatched to the idle partner.

Example: If the time slot is 100 milliseconds, and job1 takes a total time of 250 ms to complete, the round-robin scheduler will suspend the job after 100 ms and give other jobs their time on the CPU.

If you had the FPP-8 option installed, the FORTRAN runtime code would detect it and use the FPP-8 to run the main program code, and the PDP-8 CPU would run as an I / O processor.

If you did not have the FPP-8, the runtime code would instead call an FPP-8 interpreter running on the PDP-8 CPU, so the program would still run, but at considerably reduced speed.

If Fred presses 1 to listen to his message, the CPU looks up the location of Fred's new message in his mailbox directory ( on the System Disk ), and directs the Disk Controller to play that message.

If released, the game would have been Atari's first 3D polygonal arcade game to use a Motorola 68000 as the CPU.

If one of the machines failed, the program could be re-started on the remaining CPU, running both sides of the I / O task with reduced throughput.

If he had married her, he'd have been asking for trouble.

If she, Pamela, were being held responsible for his crimes, then hers must be the final act of expiation.

I showed her the shower and tub, and she said, smiling, `` If you really don't mind, I think I'll get clean in the shower, then soak for a few minutes in your tub.

If it were not for an old professor who made me read the classics I would have been stymied on what to do, and now I understand why they are classics ; ;

If it were not that I knew who it was I could have mistaken it for my Aunt so well did her clothes fit him.

`` If Blue Throat has his way he'll keep us all cooped up in here for days '', he said.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If living Jews were unavailable for study, the Bible was at hand.

If he had been `` liquidated '' in some way, he would have become a martyr, a rallying point for people who shared his ideas.

If we examine the three types of change from the point of view of their internal structure we find an additional profound difference between the third and the first two, one that accounts for the notable difference between the responses they evoke.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If we grasp this opportunity to build an age of productive partnership between the less fortunate nations and those that have already achieved a high state of economic advancement, we will make brighter the outlook for a world order based upon security and freedom.

`` If you become a Baptist, I will not '', Ann informed her husband, but sweeping her threat aside Adoniram continued to search for an answer to the personal dilemma in which he found himself.

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

If his scholarship and formal musicianship were not all they might have been, Mercer demonstrated at an early age that he was gifted with a remarkable ear for rhythm and dialect.

If only for this modest masterpiece of military history, Blenheim is likely to be read and reread long after newer interpretations have perhaps altered our picture of the Marlborough wars.

If, as Reid says, `` nearly all his poetry was produced when he was not taking opium '', there may be some reason to doubt that he was under its influence in the period from 1896 to 1900 when he was writing the poems to Katie King and making plans for another book of verse.

If Robinson was a liar and a slanderer, he was also a very canny gentleman, for nothing that Pike could do would pry so much as a single word out of him.

If Gorton wanted peace and quiet for his complicated meditations this is where he should have had it.

If she wanted to borrow any sum of money in expecting the arrangements of Congress, it would not become a stranger, unknown to her, to offer himself for that purpose.

If the hardships of the winter at Valley Forge were trying for healthy men, they were, of course, much more so for those not in good health.

If his circumspection in regard to Philip's sensibilities went so far that he even refused to grant a dispensation for the marriage of Amadee's daughter, Agnes, to the son of the dauphin of Vienne -- a truly peacemaking move according to thirteenth-century ideas, for Savoy and Dauphine were as usual fighting on opposite sides -- for fear that he might seem to be favoring the anti-French coalition, he would certainly never take the far more drastic step of ordering the return of Gascony to Edward, even though, as he admitted to the English ambassadors, he had been advised that the original cession was invalid.
