Processor vs. Coprocessor: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 8, 2023
A processor is the central unit that performs core computing tasks, while a coprocessor is a secondary processor designed to support the main processor by handling specific functions.
Key Differences
The processor, often referred to as the central processing unit (CPU), is the primary component of a computer that executes instructions. In contrast, a coprocessor works alongside the processor, handling specialized tasks to enhance overall performance.
Processors are designed for general-purpose computing, performing a wide range of tasks. Coprocessors, on the other hand, are tailored for specific operations like graphics processing or mathematical calculations.
Every computer requires a processor to function, as it's the core of computational operations. A coprocessor is an optional addition that can improve efficiency in certain tasks, but isn't essential for basic computer operation.
The speed and efficiency of a processor are crucial for the overall performance of a computer. Coprocessors, while enhancing performance in specific areas, depend on the main processor to coordinate overall computing tasks.
Processors are versatile and handle a variety of tasks, from running applications to managing system operations. Coprocessors, in contrast, are often dedicated to tasks like floating-point calculations, thereby easing the load on the main processor.
