MultiprocessingMultiprocessing means having more than one processor operating on the same memory but executing processes simultaneously. In a multiprocessing system multiple processors are employed to executed more than one activity at time, whenever massive data processing is to be carried out at regular intervals. Multiprocessor. Because many of the major activities of the data processing are concurrently running by the different processors. However, it is essential to provide synchronization between the multiple processor they access common memory such that no part of the data processing work should be neglected by the individual processor with a presumption that the other processor will do it. A multiprocessing system with several working together at a time will provide a multiprogramming environment. Multiprogramming allows multiple programs to reside in separate areas of main memory at the same time. With this approach, it is possible to maintain two or more jobs simultaneously in execution or in states of execution. Multiprocessor computer systems are expensive and found their use only in complex data processing application and in high speed floating point numerical computation application in Industry and Research fields. |
