Hands-On RTOS with Microcontrollers

Introducing multi-core and multi-processor systems 

First, let's get our terminology straight. A multi-core design is a single chip with multiple CPUs inside it, with at least some memory shared between the cores:

Multi-core parts span a very broad range, from the larger, 64-bit parts that have multiple identical CPU cores to the ARM big.LITTLE architecture, which incorporates both high-bandwidth CPUs and power-conscious MCUs in the same package. Recently, multi-core MCUs have also become more commonly available. Graphics processing units (GPUs) can also be grouped into the multi-core category.

A multi-processor system is one where there are ...
