Three design models for multicore systems

What are multicore devices?
A microprocessor that combines two or more independent processors into a single package or IC. Multicore chips allow for greater increases in computing power as compared to a single CPU continually made to run faster. In general, multicore microprocessors allow a computing device to exhibit some form of thread-level parallelism (TLP) without including multiple microprocessors in separate physical packages. This form of TLP is often known as chip-level multiprocessing.

What is a processor?
Refers to a system that accepts a program as input, prepares it for execution and executes the process defined with data to produce results. Can be a short term for a microprocessor or central processing unit (CPU) in computer.

What is an embedded system?
An embedded system refers to any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Embedded systems generally use microprocessors, or sometimes custom-designed chips or both. It is used in various applications such as vehicles, machine tools and consumer electronics.
