All processors usually share the same main memory and I/O devices, allowing them to cooperate on
tasks. The main goal of multiprocessor systems is to:

• Increase performance
• Support parallel processing
• Improve system reliability

2Basic Components of a Multiprocessor System 1. Multiple CPUs

Two or more processors execute instructions simultaneously. 2. Shared Memory

All processors access the same main memory to read and write data. 3. Interconnection Network

A communication path that connects processors to memory and I/O devices. Examples include:

• System Bus
• Crossbar switch
• Multistage networks

2.3 Operating System

The operating system manages the processors and distributes tasks among them.

Types of Multiprocessor Systems

Symmetric Multiprocessing (SMP)

In SMP systems, all processors are equal and share the same memory and operating system.
