Multiprocessing and Coprocessor

Study Notes

Multiprocessing and Parallel Computing

Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system to execute multiple instructions simultaneously.

Coprocessor

A coprocessor is a special-purpose processing unit that assists the central processing unit (CPU) in executing specific types of instructions.
The coprocessor offloads specific tasks from the CPU, freeing it to perform other processing activities.

Multicore Microprocessor

A multicore microprocessor is a single integrated circuit that contains two or more processing units (cores) that can execute instructions independently.

Coprocessor vs. Multicore Microprocessor

A coprocessor is a separate processing unit that assists the CPU, whereas a multicore microprocessor has multiple processing units within a single chip.
Coprocessors are specialized for specific tasks, whereas multicore microprocessors are general-purpose processing units.

Component Roles

Coprocessors are responsible for executing specific types of instructions while the CPU works on another processing activity.

Parallel Computing

Parallel computing is the simultaneous execution of multiple instructions or tasks across multiple processing units or nodes to speed up processing times.

Massively Parallel Processing Systems

Massively parallel processing systems use hundreds or thousands of processing units to execute tasks in parallel, achieving high processing speeds.

Grid Computing

Grid computing is a distributed computing system that coordinates and shares computing resources across a network to achieve a common goal.

Cloud Computing

Cloud computing is a model for delivering computing services over the internet, providing on-demand access to a shared pool of computing resources.

Storage

Secondary storage refers to non-volatile storage devices that hold data when the power is off, such as hard disk drives or solid-state drives.

Description

Learn about multiprocessing and coprocessors, which involve the simultaneous execution of multiple instructions and the part of the computer that speeds processing by executing specific types of instructions while the CPU works on another processing activity.
