Three design models for multi-core systems

Keywords:multi-core processors  planar pattern  grid pattern  SMP 

This article looks into three design models of multi-core processors: planar pattern, grid pattern, and SMP system. Use of low-cost and low power multi-core processors are now the trend in embedded design.

The planar pattern is an example of a broad and diverse category of multi-core designs, collectively called asymmetric multi-processing (AMP or ASMP). The grid-on chip or grid pattern covers any multi-processor system made up of a collection of fully independent, networked nodes. A symmetric multi-processing (SMP) system, meanwhile, has a single-image operating system that runs on two or more identical processing cores that share memory.
