Tools and Techniques Surmount the Multi-core Challenge
August 4, 2008 11:15 am | by Jon Titus, Senior Technical Editor | Articles | CommentsMulti-processor computers have existed for some time, but only within the last few years have engineers had the opportunity to buy off-the-shelf chips with more than one processor or "core." These devices come in two varieties; symmetrical and asymmetrical. The first group provides multiple "clones" of the same core CPU, thus the term symmetrical. The second group includes devices that put different types of CPUs, DSPs, and accelerators in a system on a chip. I'll concentrate on the former multi-core technologies.
