What is the difference between a multiprocessor and a multicore system

In a uni-processor system, only one process can be executed at a time and after its execution, the next process will be executed and so on. But in a multiprocessor system, the different process can be assigned to different processors and this, in turn, decreases the overall process execution time by the system. A dual-processor system can execute two processes at a time while a quad-processor can execute four processes at a time.

We have seen what a multicore system and a multiprocessor system is. These are two different things. The only common thing that they share is both want to increase the processing speed of the system by executing more than one processes at a time. Some of the differences between these two are:.

Most popular in Difference Between. Most visited in Operating Systems. Every CPU can operate on local data to perform computational tasks. Latest computers have multiple CPUs each with multiple cores to read and execute several instructions at a time. A multicore is a single CPU or processor with two or more independent processing units called cores that are capable of reading and executing program instructions.

Multiprocessor is a system with two or more CPUs that allows simultaneous processing of programs. Multicore executes a single program faster. On the other hand, multiprocessor executes multiple programs faster.

Multiprocessor systems are more reliable than multicore systems. A multiprocessor has more CPUs. Failure in one will not affect the other CPUs. It is more tolerant to faults. The multicore systems have less traffic compared to a multiprocessor because all the cores are integrated into a single chip.

The difference between multicore and multiprocessor is that multicore refers to a single CPU with multiple execution units while multiprocessor refers to a system that has two or more CPUs. Modern computers have multiple CPUs each with multiple cores. She is passionate about sharing her knowldge in the areas of programming, data science, and computer systems. Figure 1: Multicore.
