• Assigns tasks
• Manages I/O operations

Slave processors only execute assigned tasks.

2.7 Advantages of Multiprocessors
1. Higher Performance

Multiple processors can execute instructions simultaneously.

2. Parallel Processing

Tasks can be divided into smaller parts and executed at the same time.

3. Reliability

If one processor fails, the system may continue operating with others.

4. Scalability

Performance can increase by adding more processors.

2.8 Challenges in Multiprocessor Systems
1. Synchronization

Processors must coordinate access to shared data.

2. Cache Coherence Problem

If each processor has its own cache, data consistency must be maintained.

3. Resource Contention

Multiple processors may compete for the same memory or bus.

Applications of Multiprocessors Multiprocessor systems are widely used in:

• High-performance computing
• Scientific simulations
• Artificial intelligence
