A multiprocessor is a computer system that has more than one central processing unit (CPU) working together to execute programs. This allows for increased processing power and improved performance, as multiple tasks can be executed simultaneously. Multiprocessor systems can be symmetric multiprocessing (SMP), where all CPUs are equal and share access to memory, or asymmetric multiprocessing (AMP), where one CPU is designated as the master and controls the other CPUs.

Multiprocessor
A multiprocessor is a computer system with multiple central processing units (CPUs) that share the same main memory and I/O devices. Each CPU can execute its own instructions independently, enabling the system to process multiple tasks simultaneously.
Key Features:
- Multiple CPUs: Contains two or more CPUs, each with its own local cache and registers.
- Shared Memory: All CPUs have direct access to the same physical memory.
- Centralized I/O: Input/output devices are connected to a central I/O module, accessible by all CPUs.
- Parallel Processing: Different CPUs can work on different tasks or portions of the same task concurrently, improving performance.
- Resource Sharing: CPUs share resources such as cache, main memory, and I/O devices.
Types of Multiprocessors:
- Symmetric Multiprocessing (SMP): All CPUs have equal access to shared resources and can run any task.
- Asymmetric Multiprocessing (AMP): Different CPUs have different roles and capabilities, such as one handling high-priority tasks and another handling low-priority tasks.
Benefits of Multiprocessors:
- Increased Performance: Multiple CPUs can work together to reduce processing time and improve overall system throughput.
- Scalability: New CPUs can be added to the system to increase capacity as needed.
- Reliability: If one CPU fails, the others can continue operating, maintaining system availability.
- Reduced Latency: Parallel processing allows for faster response times to user requests and inputs.
- Cost-Effectiveness: Multiple CPUs can share resources, reducing the overall cost of the system.
Applications:
Multiprocessors are used in various applications, including:
- High-performance computing
- Data centers
- Scientific research
- Cloud computing
- Enterprise servers
- Embedded systems
