AMP Full Form in Computer

What is AMP Full Form in Computer?

The AMP full form in the computer is Asymmetric Multiprocessing. Asymmetric Multiprocessing is a technique for distributing processing load on a multiprocessor computer in which each processor is allocated certain tasks to complete. Prior to the introduction of symmetric multiprocessing, asymmetric multiprocessing was the only way to handle several CPUs. It has also been utilized to provide less expensive options in systems when SMP was available.

Advantages of AMP:

In an AMP system, a process is always executed on the same CPU, even when other CPUs remain idle. As a result, one CPU may end up being under or over utilized. To address the issue, the system may enable apps to move dynamically from one CPU to another. However, doing so may require complex checkpointing of state information or a service disruption as the application is halted on one CPU and restarted on another. Furthermore, such a migration is difficult, if not impossible, if the CPUs run different operating systems.

Benefits of AMP:

With AMP, you may control how the shared hardware resources utilized by apps are distributed across the CPUs. Normally, this resource allocation is done statically during startup time and comprises physical memory allocation, peripheral usage, and interrupts handling. While the system could dynamically assign resources, this would require complicated cooperation between the CPUs.
