Definition: A coprocessor is a specific hardware component in a microprocessor that processes data from other processors. These components are typically found in x86-based microprocessors, where they are used to perform tasks such as arithmetic and logical operations on multiple inputs simultaneously. In computer science, coprocessors play an important role in parallel processing, where multiple processors can work together without interfering with each other's execution. They are also often used in distributed computing systems to distribute workload across multiple machines or nodes. The
