What is Parallel Arbitration Logic?

Parallel Arbitration Logic provides a mechanism through which the shared resources can be accessed by the processors in a multiprocessor system in a controlled and efficient way. Unlike the sequential arbitration logic, where the processors can access the resources one by one on a priority basis, In parallel arbitration logic these resources can be accessed by the processors simultaneously.

Parallel Arbitration Logic In Multiprocessors

In multiprocessor systems, the arbitration logic is used to make sure that at a single point in time, only one processor can access the system bus. In this article, we are going to see how the functioning of parallel arbitration logic in multiprocessors takes place.
